Evidence from Flavonlids suggests hewrt flavonoid-rich Flavonoide can reduce blood pressure, Flavonodis endothelial function, heatr dyslipidaemia, lower arterial stiffness, and lessen inflammation [ Cognitive function improvement strategiesbealthheaft ].
Previous cohort studies have examined the association of flavonoid intake with IHD, and recent meta-analyses of these Flavonoide indicate that higher intakes of the flavonol, anthocyanin and flavanol flavonoid subclasses hewrt associated with hhealth significantly heartt risk of IHD [ 111213 ].

Thus, we hypothesize, that higher habitual dietary flavonoid consumption helth also be associated with a lower risk of IHD, the primary contributor to CVD events.

The primary outcome was defined as all first-time IHD events IHD-coded hospitalizations and deaths using ICD codes I20—I25 and ICD-8 codes Unknown deaths which may or may not be IHD-related-related were not considered in the primary outcome.
Hospitalizations for IHD were extracted from The Danish National Patient Register, a national collection of hospital discharge information, and death data was obtained from The Danish Register of Causes of Death. To verify the registry-based outcomes, we re-examined associations only using cases that have been previously medically reviewed and validated for first-time acute myocardial infarction ICD I21with a follow-up time frame of 19 years between February and April [ 24 ].
Information on lifestyle factors and medical history including sex, age, anthropometry, physical activity, education, smoking habits, alcohol consumption, medication use and diet were obtained from the baseline assessment.
For hypertension and diabetes mellitus, self-reported data were used due to the underreporting of these diagnosis in the Danish National Patient Register DNPR [ 23 ].
Comorbidities of peripheral artery disease, ischemic stroke, chronic kidney disease, chronic obstructive pulmonary disease, and atrial fibrillation were identified by ICD codes dated prior to enrollment Supplementary Table 1.
The association between flavonoid intake exposures and IHD risk was modeled using restricted cubic splines within Cox proportional hazards models. Time-to-event was calculated for each participant from enrollment until the end of follow-up August,an IHD event, death, or emigration loss to follow-up [0.
Given the etiological focus, all deaths were censored rather than treated as a competing risk [ 25 ]. Proportional hazards assumptions were tested by visually inspecting log-log plots of the survival function versus time, with no violation found.
Analyses stratified by smoking status were additionally adjusted for pack-years of smoking duration in the relevant sub-group.
During a median [IQR] of A total of 11, participants died from causes other than IHD and without a prior diagnosis of IHD. The median age at baseline was 56 years, females constituted Participants with higher flavonoid intakes tended to smoke less, exercise more, maintain a lower BMI, and have a higher education and income.
Those consuming more flavonoids also tended to eat more fish, fiber, whole-grain products, fruits, and vegetables, and eat less red and processed meat Table 1. For intakes of total flavonoids beyond quintile 1, we observed a trend towards a lower risk of IHD, however this was not significant in models adjusted for demographics and lifestyle characteristics Model 2; Table 2 ; Fig.
Hazard ratios are based on Cox proportional hazards models adjusted for age, sex, BMI, smoking status, physical activity, alcohol intake, education, socioeconomic status incomeaspirin use, antihypertensive medication use and statin use and are comparing the specific level of flavonoid intake horizontal axis to the median intake for participants in the lowest intake quintile.
Using only validated first-time cases, participants were hospitalized or died from acute myocardial infarction. Although a lower risk of IHD was seen for higher intakes of total flavonoids, the association was not significant Model 2; Supplementary Fig.
Stratified by sex, and after adjustment for demographic and lifestyle factors, higher total flavonoid intake was significantly associated with lower IHD risk in males but not females Model 2; Supplementary Table 2. However, with additional adjustment for dietary confounders, no significant association was present in either sex Model 3; Supplementary Table 2.
When models were further adjusted for dietary covariates there was no compelling evidence of a lower IHD risk in either sex, with higher intakes, of any subclass Model 3; Supplementary Table 2. Stratified by smoking status, and after adjustment for demographic and lifestyle factors, higher total flavonoid intakes were significantly associated with lower IHD risk in ever-smokers but not never-smokers Model 2; Supplementary Table 3.
However, following additional adjustment for dietary confounders, a significant lower risk of IHD was not seen in ever-smokers nor never-smokers Model 3; Supplementary Table 3.
Of the individual flavonoid subclasses, among those who had never smoked, no significant inverse associations were seen Model 2; Model 3; Supplementary Table 3.
In this prospective cohort study, of 54, Danish adults, aged 50—64 years, who were followed for up to 23 years, we did not observe clear associations between intakes of total flavonoids or flavonoid subclasses with IHD risk. Nor did we observe compelling evidence of effect modification by sex, such that higher flavonoid intakes associated with lower IHD risk in one sex, but not the other.
Thus, while the findings do not support a strong benefit of flavonoid intake on IHD risk, they also do not exclude the possibility that flavonoids may have a modest protective role in IHD, particularly for current or former smokers.
It is of particular relevance that we have observed in our previous investigations of the relationship between flavonoid intake and CVD in the Danish, Diet, Cancer and Health Study, that higher intakes of flavonoids was clearly associated with a lower risk of total atherosclerotic CVD and, more specifically, peripheral artery disease and ischemic stroke in the total population [ 141516 ].
This suggests that the observed associations between flavonoid intake and IHD risk may be a consequence of differing underlying dietary patterns. Given our promising prior results, and the common etiology of atherosclerosis in CVD, it is thus surprising that the present analysis did not find clear evidence of associations between flavonoids and IHD.
Similar seemingly disparate findings have previously been observed. For example, in the Health Professionals Follow-Up study, higher flavanone consumption strongly associated with a lower risk of stroke but not myocardial infarction, and in the NutriNet-Santé Cohort, higher intakes of flavonols and catechins were associated with a lower risk of stroke but not coronary heart disease [ 2728 ].
The reasons for the differing results between CVD types are less certain, yet may allude to differences in the underlying pathology and the relative contributions of flavonoids on these pathologies. Ischemic stroke, PAD and IHD are often discussed as diseases of the same entity: atherosclerotic arterial disease.
The pathophysiology of these diseases involve many common risk pathways, but it is possible that inflammation, hyperlipidaemia and hypertension, along with other risk factors, contribute differentially to atherosclerosis of the cerebral, coronary and peripheral vascular beds.
In fact, growing evidence does suggest a heterogeneous impact of atherosclerotic risk factors on different vascular regions. Several cohort studies have reported higher blood pressure is a stronger predictor of ischemic stroke than IHD and that elevated blood lipids appear to play a more important role in the development of IHD than ischemic stroke [ 293031 ].
Consequently, the effect of reducing blood pressure or blood lipids may be more pronounced on the CVD type with which the risk factor is more strongly associated [ 32 ]. For flavonoids, the evidence to date appears to indicate a stronger anti-hypertensive action, than hypo-lipidemic action [ 813 ].
As a result, the habitual intake of flavonoids may more strongly associate with ischemic stroke than IHD, which could explain our limited findings. A growing body of data also reports hypercoagulability is a stronger risk factor for ischemic stroke than for myocardial infarction [ 33 ].
Flavonoids appear to modulate key events in the pathogenesis of thrombosis via multiple mechanisms, such as reducing platelet activation, enhancing NO production and blocking TxA 2 receptors [ 34 ].
As such, the anti-thrombotic activities of flavonoids may be further contributing to divergent associations among CVD types. It is also known, that even though IHD, cerebrovascular disease, and PAD all share atherogenic pathophysiology, the mechanisms underlying the occurrence of acute events largely differ.
Indeed, while progressive stenosis of carotid and of peripheral arteries primarily account for non-cardio-embolic ischemic strokes and for symptomatic PAD, most acute coronary syndromes are caused by atherosclerotic plaque ruptures at sites with only mild arterial narrowing [ 35 ].
It has been shown that coronary atherosclerotic plaque morphology is a more important prognostic factor for acute cardiac events than the degree of stenosis, with most events occurring in plaques with a phenotype characterized by a thin-cap fibroatheroma and a large plaque burden [ 36 ].
Therefore, the impact of flavonoids may address diseases in which the degree of arterial stenosis represents a stronger pathophysiological component. In contrast to the results of our study, among previous cohort investigations of flavonoids, their subclasses and IHD, significant inverse associations have been observed [ 7 ].
Indeed, other cohort studies have observed evidence for a benefit of intake of certain subclasses on IHD risk, but not for cerebrovascular disease [ 3738 ]. These findings are difficult to reconcile, yet may be due to one or more underlying, unidentified, clinical e.
Indeed, we saw significant beneficial associations for all subclasses and total flavonoid intake in models adjusted for age and sex, but when socio-demographic data was added, nearly all these associations became statistically non-significant. It may therefore be, that the present study may not have failed to reproduce previously identified associations, instead the previous studies may have failed to identify all relevant confounders as well as the current investigation.
Indeed, we found evidence of effect modification by smoking status, which is likely of consequence when examining results of different cohort studies.
In the present study, we observed effect modification by smoking status. The association between flavonoid intake and IHD was present in ever-smokers but not never-smokers. This is of note as in our previous studies of flavonoid intake and disease risk in the Danish Diet Cancer and Health cohort, those diseases for which smoking is a more influential risk factor, have all been more strongly associated with flavonoid intake.
This extends to peripheral artery disease [ 15 ], abdominal aortic aneurysm [ 15 ], and chronic obstructive pulmonary disease [ 39 ]. There are several intriguing explanations for these observations.
With regards to IHD specifically, cigarette smoking increases the risk at least partly through increasing systemic thrombotic propensity, oxidative stress and inflammation—mechanisms which appear attenuated via flavonoid intake [ 344041 ]. Despite this, we have previously shown that smokers consuming high flavonoids still have a much higher risk of CVD than non-smokers consuming low flavonoids [ 14 ].
As such, public health campaigns for the primary prevention of IHD should prioritize smoking cessation. This study has several limitations.
: Flavonoids and heart health| Related Articles | The risk factors are configurable; however, to date, the prevention or control measures, especially in developing countries, have been lacking. In the coming years, a population policy paired with a high-risk CVD prevention strategy could significantly alleviate the burden of disease 5 , 6. Physical activity protects against a variety of chronic conditions at any age. Tobacco and smoking are other modifiable factors associated with the progression of cardiovascular disorders. Tobacco smoke affects the endothelium, stimulates arterial fat deposits, enhances clotting, tends to increase LDL cholesterol and decrease high-density lipoprotein HDL cholesterol, and promotes coronary artery spasticity 8. There is a clear association between abnormal blood lipid concentrations and the likelihood of coronary artery disease, cardiac arrest, and cardiovascular failure. Abnormal blood lipids are also linked to dietary habits. A diet rich in saturated fats and trans fats contributes to high cholesterol levels 9 , Alcohol use has been observed to affect the cardiac muscle and raise the risk of stroke and cardiac arrhythmia. Other complications associated with drinking too much alcohol include high blood pressure, acute myocardial infarction, cardiomyopathy, liver cirrhosis, aggression, and suicide 11 , Obesity is one of several significant risk factors for CVD as well as other hormonal disorders, such as diabetes. As shown by the rising rate of obesity, the general human population is becoming overweight. There are approximately million adults globally who are obese and 1 billion who are overweight and suffer from the risk of CVDs Reactive oxygen species are reactive molecules that are continuously formed in organisms by enzymatic reactions However, many proven health issues related to heart disease are being attributed to an increase in reactive oxygen species production, a condition called oxidative stress Numerous epidemiological trials have found that daily flavonoid consumption is linked to a lower risk of heart disease Flavonoids area type of natural product with a polyphenolic structure and basic components that consist of 3 heterocyclic rings 2 phenyl rings and a heterocyclic ring. These 3 elements combine to form the flava kernel, which is the central component of flavonoids Flavonoids have been the subject of significant interest by experts in recent times due to the wide spectrum of possible benefits they provide. Owing to the variability of the molecular structures, complicated long-term research, and several reports have indicated that polyphenolic compounds can be useful as an adjunctive therapy for the management and cure of inflammatory diseases Flavonoids, a class of natural products with complex phenolic structures, are present in berries, herbs, nuts, wood, roots, branches, bulbs, coffee, and tea. The beneficial health effects of these natural substances are well recognized. Flavonoids are also known to be an essential ingredient in a multitude of pharmaceutical, nutraceutical, medical, and cosmetic products. This is due to their anti-oxidant, anti-inflammatory, anti-mutagenic, and anti-carcinogenic effects, and their ability to modulate crucial cellular enzyme activity Rutin and quercetin are reported to regulate and restore elevated blood pressure and promote the anti-oxidant defense system. Lipid peroxidation was increased and the anti-oxidant enzymes were down regulated. Treatment with rutin and quercetin for nearly 2 weeks resulted in notable reversals of these indices compared to the animals fed only the high-salt diet the without treatment group. The high-salt diet also resulted in noteworthy increments in the serum urea, creatinine, glucose, triglycerides, low-density-lipoprotein, and total cholesterol levels. The administration of rutin and quercetin retarded the effects of the high-salt diet for these biochemical indices. The reference drug, nifedipine, was found to be less effective than rutin and quercetin. The outcomes of the study indicate the roles of rutin and quercetin as anti-hypertensive agents and anti-oxidants The administration of rutin resulted in the restoration of baroreflex sensitivity in 2-kidneyclip rats. The cardiac contractility was also decreased, and vasorelaxation tended to be restored. The rutin treatment also resulted in a decrement in lipid peroxidation In another independent study that used the 2-kidneyclip model, the administration of rutin restored systolic and diastolic blood pressure. The restoration of glutathione and plasma renin was observed to be dose dependent In a clinical study, the administration of quercetin was found to result in a decrement in hypertension in stage 1 hypertensive patients, including reductions in systolic, diastolic, and mean arterial pressures The anti-hypertensive effects of catechin and its derivatives are widely acknowledged. Tea, specifically green tea, is an important source of catechin. Tea is widely consumed worldwide 25 , and contains anti-oxidants that have been proven to be beneficial to health. Numerous studies have reported that the consumption of green tea has beneficial effects on hypertension. Indeed, the administration of catechin-rich green tea has been shown to result in a decrement in systolic and diastolic blood pressure. The lipid profile was restored to normal levels. The decrement in LDL cholesterol is prominent. Alterations in blood glucose levels due to normotension appear to be significant Catechin-rich oil has been reported to have an anti-hypertensive effect, as it upregulates nitric oxide NO levels. Research has shown a notable decrease in the wall-to-lumen ratio to near normal values under NO deficiency Benifuuki tea is a popular green tea consumed in Japan. It is a rich source of - -epigallocatechinO- 3-O-methyl gallate. This polyphenol has a significant effect on the inhibition of the angiotensin I-converting enzyme. Benifuuki tea has also been shown to have an anti-hypertensive effect, especially on systolic pressure Oranges are one of the richest sources of hesperidin. Hesperidin is one of the major anti-oxidant flavonoids In a preclinical study, the anti-hypertensive effects of glucosyl hesperidin and hesperetin were evaluated in animal models spontaneously hypertensive rats and normotensive Wistar-Kyoto rats. Similarly, the intraperitoneal administration of hesperitin to spontaneous hypertensive rats resulted in a notable decrement in systolic blood pressure. Such a response was associated with the inhibition of NO synthase. The effect was observed due to NO-mediated vasodilation The possible anti-hypertensive effects of hesperidin have been studied in type-2 diabetes patients. In a clinical study, patients were administered a mg hesperidin capsule every day for 6 days. The placebo group received a starch filler capsule. Systolic and diastolic blood pressure were taken into consideration when determining the blood pressure of the patients. The levels of tumor necrosis factor- TNF -α and interleukin IL -6 were notably decreased in the hesperidin treated group. An increase in total anti-oxidant capacity was also observed. This effect may be due to one of the metabolites of hesperidin; that is, hesperetin-O-glucuronide. The metabolite is associated with endothelium-dependent vasodilation and the suppression of inflammation of endothelial cells The pharmacological effects of the administration of hesperidin and glucosyl hesperidin along with naringin were evaluated in stroke-prone spontaneously hypertensive rats. The study showed that the administration of these flavonoids resulted in the restoration of blood pressure and a decrement in thrombolytic tendency. The biosynthesis of NO was also increased. Further, the endothelial function was restored due to the administration of these natural flavonoids Genistein is another documented isoflavone present in various soybeans and soy products. Genistein has been the subject of considerable interest by the biomedical community due to its apparent positive effects on major human illnesses, such as cancer. Mechanistically, genistein has a propensity for apoptotic activation, arresting the cell cycle, and also has anti-angiogenic, anti-cancer, and anti-apoptotic effects. Genistein has a tendency to regulate NO biosynthesis. Specifically, it increases the expression of NO. It also increases aortic wall thickness and decreases hypertension In high-sodium chloride NaCl diet-fed rats, the administration of genistein blunted hypertension. Studies also suggest that it has anti-hypertensive effects associated with the autonomic nervous system. The key mechanism by which genistein mediates cardiovascular function is via its association with estrogen receptors. Genistein is capable of binding to the estrogen-receptor beta Erβ and activating ER-dependent gene transcription. Genistein also greatly affects the protein expression implicated in vascular tone control; that is, the atrial natriuretic peptide receptor, endothelin converting enzyme 1, angiotensin converting enzyme, atrial natriuretic peptide receptor, and endothelial NO synthase 34 , Erythropoietin and its receptor play a defensive role in the prevention of pulmonary hypertension. In one study, the administration of genistein in hypobaric conditions prevented vascular remodeling and pulmonary hemodynamics. Vasodilation associated with phosphatidylinositol 3-kinase and NO was also observed Due to the rise in hypoxia-inducible factor HIF -1α, hypertension-induced myocardial injury is often followed by impaired myocardial glucolipid metabolism. The potential benefits of apigenin for hypertension have been studied. Research has shown that the administration of apigenin resulted in a decrement in blood pressure and restored heart weight and serum angiotensin II. Additionally, apigenin administration resulted in a decrement in the expression of carnitine palmitoyltransferase-1, peroxisome proliferator-activated receptor-α, glycerolphosphate acyltransferase genes, and glucose transporter-4 proteins. It has been suggested that apigenin may have beneficial effects in hypertensive cardiac hypertrophy Table 1 details the effects of other flavonoids on hypertension.

Arrhythmia refers to a diverse variety of disorders associated with abnormalities in heart rate and rhythm. Based on heart rate, arrhythmias are classified as bradyarrhythmias or tachyarrhythmias. They are also classified based on their origin, mode of propagation, and the syndromes with which they are associated. Patients with arrhythmias can present with a wide range of clinical symptoms, ranging from being completely asymptomatic to sudden cardiac arrest. As arrhythmias can be paroxysmal, assessing their exact prevalence is challenging. The event of cardiac arrhythmia addresses the diagnosis and management of multiple arrhythmias, and also the involvement of multidisciplinary teams in the care of such cases. Quercetin has been observed to have anti-ischemic and anti-arrhythmic effects, and has a beneficial role in the homeostasis of patients with ischemic heart disease A total decrement in the depression of ST segment depression was also observed due to quercetin administration The Ganshanbian herb is used in the treatment of cardiac arrhythmias. In one study, the flavonoid-rich fraction of Ganshanbian was isolated and evaluated to examine its anti-arrhythmic effects in an animal model. The administration of the flavonoid-rich fraction to the animals resulted in an increase in the appearance time and a decrease in the duration of ischemia and heartbeat. There was an increase in the expression of cell membrane associated messenger ribonucleic acid mRNA of L-calcium channels α type Ca L-α1C. The potential anti-arrhythmic effects of flavonoids from the Chinese medicine Viscum coloratum have also been evaluated. The administration of 0. In another study, the administration of the flavonoid-rich fraction of Viscum coloratum shortened the action potential and led to a decrement in the arrhythmia index. Eur Respir J.

Subjects Coronary artery disease and stable angina Epidemiology Risk factors. Results During follow-up, IHD events were recorded. Conclusions While we did not find clear evidence that higher habitual dietary flavonoid intake was associated with lower IHD risk, these results do not exclude the possibility that certain subclasses may have a protective role in prevention of IHD among population sub-groups; this was evident among smokers, who are at a higher risk of atherosclerosis. Methods Study design and population The details of the Danish Diet, Cancer, and Health study, its procedures and population characteristics, have been reported elsewhere [ 17 ]. Assessment of diet and flavonoid intake Habitual dietary intake was estimated using a item food frequency questionnaire FFQ which was specifically designed and validated to assess food consumption in Denmark [ 18 , 19 ]. Outcomes ascertainment Danish nationwide registries were used to identity and record cases of IHD, classified until according to the International Classification of Diseases ICD 8 th revision ICD-8 and thereafter, according to the 10th revision ICD [ 22 ]. Validated case analysis To verify the registry-based outcomes, we re-examined associations only using cases that have been previously medically reviewed and validated for first-time acute myocardial infarction ICD I21 , with a follow-up time frame of 19 years between February and April [ 24 ]. Covariates Information on lifestyle factors and medical history including sex, age, anthropometry, physical activity, education, smoking habits, alcohol consumption, medication use and diet were obtained from the baseline assessment. Statistical analysis The association between flavonoid intake exposures and IHD risk was modeled using restricted cubic splines within Cox proportional hazards models.

Discussion In this prospective cohort study, of 54, Danish adults, aged 50—64 years, who were followed for up to 23 years, we did not observe clear associations between intakes of total flavonoids or flavonoid subclasses with IHD risk. Data availability The data that support the findings of this study are available from Diet, Cancer and Health Steering Committee at the Danish Cancer Society but restrictions apply to the availability of these data, which were used under license for the current study, and so are not publicly available.

For one, including foods with flavonoids in your diet may be an effective way to help manage high blood pressure. At least five subtypes of flavonoids have a demonstrable effect on lowering high blood pressure, according to a review published in Also, the flavonoids found in tea, coffee, and soy may help lower your risk of having a heart attack or stroke. One study published in the Journal of Translational Medicine found that people who consumed higher levels of flavonoids as part of their diet had a lower risk of experiencing a cardiovascular event. However, more research is needed to prove the cardiovascular benefits of flavonoids. A diet high in flavonoids may also decrease your risk of type 2 diabetes. Results of a meta-analysis done in suggest that a high intake of dietary flavonoids correlates with a lower risk of type 2 diabetes. However, more research is needed to prove the efficacy of flavonoids as blood sugar regulators. The anti-inflammatory and antioxidant effects of flavonoids have also encouraged researches to study their potential as anticancer drugs. Research has shown that certain flavonoids may help stop cancer cells from multiplying. Including foods with flavonoids and keeping a healthy diet may decrease your risk of getting certain cancers. Still, more studies are needed to confirm whether flavonoids can be used as an effective cancer therapy. Flavonoids have many health benefits and are easy to include in your diet. They have powerful antioxidant properties and can help manage symptoms of inflammation. Researchers are only starting to learn the potential of flavonoids as medicine, but it seems promising.

| Contact Us | They're all rich in flavonoids, the chemical compounds found in plants that give them color — and medicinal powers. Research shows flavonoids provide a wide range of health benefits , from fighting cancer and lowering the risk for heart disease to preserving brain function. They've even been used to fight wrinkles. Antioxidants help fight inflammation and aging. Flavonoids also have properties that could help prevent blood clots. And a study published last year in the American Heart Association journal Hypertension suggests flavonoids in foods such as berries, red wine, apples and pears may influence gut bacteria in a way that lowers blood pressure. Because of this, flavonoids play a central role in the Mediterranean, DASH and MIND diets, the eating patterns most recommended by heart and brain health experts. While there are some differences, all three place a heavy focus on flavonoid-rich fruits, vegetables, nuts and beans. But most people in the U. aren't getting enough flavonoids, largely because they don't eat the recommended daily allowance of fruits and vegetables. Federal dietary guidelines recommend adults eat 1. But only 1 in 10 U. adults eat that many vegetables and only 1 in 8 eat a sufficient amount of fruit, according to data from the Centers for Disease Control and Prevention. The good news is, flavonoids are found in such a wide range of fruits, vegetables and other foods that it shouldn't be hard to fit them into your diet, Petersen said. They're found in berries of all kinds, cherries, apples, grapes, leeks and leafy green vegetables such as spinach, romaine lettuce and kale.
