Conflicting Effects of Coffee Consumption on Cardiovascular Diseases: Does Coffee Consumption Aggravate Pre-existing Risk Factors? Although smokers metabolize caffeine more rapidly than nonsmokers due to the well-known CYP1A2-inducing effect of smoking,32 the extent of CYP1A2 induction among smokers is lower for carriers of the *1F allele.25,26 Thus, smokers with the slow metabolizer genotype may still have an increased risk of MI with increasing coffee consumption.

During the follow-up period, 309 participants died. 1994; 72: 269–275. Similar results were observed when men and women were examined separately. 2006;295(10):1135-1141 (doi:10.1001/jama.295.10.1135). Marilyn C. Cornelis; Ahmed El-Sohemy; Edmond K. Kabagambe; et al. Coffee intake from 1 to 4 cups per day was not associated with any increase in coronary heart disease occurrence compared with 1 cup or less per day (odds ratio, 1.01; confidence interval [0.93, 1.11]). In summary, consistent with most case-control studies, we found that increased coffee intake is associated with an increased risk of nonfatal MI. 1 Coffee intake and risk of MI by CYP1A2 genotype among subjects less than 50 years of age. Rasmussen BB, Brix TH, Kyvik KO, Brosen K. The interindividual differences in the 3-demethylation of caffeine alias CYP1A2 is determined by both genetic and environmental factors. Eligible controls were identified within 1 week of the case selection. Subclinical CHD or other somatic causes are unlikely to account for our findings, which also appear not to be explained by established risk factors for AMI. The last 15 years has brought to light a significant amount of medical research correlating coffee consumption to an increased risk for non-fatal myocardial infarction (MI) or heart attack. Physical features of subjects including genetic variations and body mass index (BMI) make it difficult to determine moderate intake of coffee for individuals in terms of caffeine metabolism. The studies exhibited heterogeneity of results. Synergism of these drugs can be attributed to their actions at ryanodine receptors. interviewed to inquire about their tobacco, caffeine, alcohol, and illegal drugs consumption, and on their practice of physical exercise. CYP1A2 1A allele are ‘rapid’ caffeine metabolizers [11,12]. To assess the fruit and vegetable intake a Food Frequency Questionnaire was administered. In all, 4923 patients (2790 men, 2133 women) with type 2 diabetes (mean age, 66 years) were followed prospectively (median, 5.3 years; follow-up rate, 99.5%). with hypertension and myocardial infarction (MI) are different between slow and rapid metabolizers as defined by CYP1A2 genotype with adjustment for confounding factors. These findings and other recent studies suggest that heavy coffee consumption increases the risk of myocardial infarction. 7. Dantrolene mitigated adverse responses in HET. Gu L, Gonzalez FJ, Kalow W, Tang BK. After adjustment for matching criteria and socioeconomic status, the OR for AMI was 2.9 (1.8-4.9) for ever hospitalized for depression. (2005) Caffeine Intake, CYP1A2 Polymorphism and the Risk of Recurrent Pregnancy Loss. In terms of cardiovascular disease (CVD), although randomized controlled trials demonstrate that intake of caffeine, the most prominent bioactive compound of coffee, leads to acute i… Subclinical CHD or other somatic causes of depressive symptoms might account for the association, however. Coffee is a major source of caffeine, which is metabolized by the polymorphic cytochrome P450 1A2 (CYP1A2) enzyme. HET receiving dietary CAF (median plasma CAF 893 ng/ml) have an exaggerated EEGTP increase compared to WT, negating genotype differences without altering blood chemistry. Ryanodine receptor (RYR1) mutations confer stress-triggered malignant hyperthermia susceptibility (MHS). HAL anesthesia produces shorter delays to isoelectric EEGTP, ECG and respiratory arrest in the HET+CAF group, whereas these measures are unaffected in WT regardless of CAF. Approximately 90% of coffee consumed in Costa Rica is filtered. Relative risks (as estimated by odds ratios) and their 95% confidence intervals were computed from multiple logistic regression analyses that controlled for smoking and other risk factors. Coffee, CYP1A2 genotype and risk of myocardial infarction. We hypothesize that dietary CAF achieving blood levels measured in human plasma exacerbates the penetrance of RYR1 MHS mutations triggered by gaseous anesthetic, affecting both central and peripheral adverse responses. Coffee consumption was associated with a lower risk of CHD. Entering the HMO arena: options for hospitals. Individuals who are homozygous for the CYP1A2*1A allele are “rapid” caffeine metabolizers, whereas carriers of the variant CYP1A2*1F are “slow” caffeine metabolizers. Customize your JAMA Network experience by selecting one or more topics from the list below. Coffee is a major source of caffeine, which has multiple physiological effects that could increase the risk of MI.17 Numerous studies have examined the association between coffee consumption and risk of MI, but the findings have been inconclusive.1-14 Caffeine is detoxified primarily through an initial N3-demethylation that is catalyzed by CYP1A2, an enzyme that displays wide interindividual variability in activity.21-23 We investigated whether a common genetic polymorphism (CYP1A2*1F) that results in a “slow” metabolizer phenotype modifies the association between intake of caffeinated coffee and risk of nonfatal MI. 1 For [population], is caffeine intake above [exposure dose], compared to intakes [exposure dose] or less, associated with adverse effects on cardiovascular outcomes? The effect of caffeine was greater for CYP1A2 ‘fast’ vs. ‘slow’ metabolisers for reaction time during exercise (− 18 ± 9 vs. − 1.0 ± 11 ms); fastest 10% reaction time at rest (− 18 ± 11 vs. − 3 ± 15 ms) and lapses at rest (− 3.8 ± 2.7 vs. + 0.4 ± 0.9) (P < 0.05). Articles published between 1966 and August 1991 examining a possible link between coffee and coronary heart disease were identified by a computer-aided literature search (Medline) and by standard bibliographic searches. The health benefits and risks of coffee have long been debated, with various outcomes reported (3). Intakes of nutrients were calculated using the US Department of Agriculture food composition data file. Compared with less than 1 cup/d, the ORs (95% CIs) of MI for 4 cups/d or more among individuals with the *1A/*1A genotype were 0.86 (0.53-1.36) for men and 1.43 (0.54-3.72) for women. Categorical and continuous nondietary and energy-adjusted dietary variables were assessed for potential confounding by measuring their effect on the model parameter estimates using the likelihood ratio test. http://jama.ama-assn.org/cgi/content/full/295/10/1135. The positive association with heavy coffee drinking was present among nonsmokers as well as smokers. In comparison with non-dependent smoking, nicotine dependence was associated with current use of psychotropic medication, psychiatric morbidity, previous suicide attempt, and earlier AODS. Shyrock JC, Belardinelli L. Adenosine and adenosine receptors in the cardiovascular system: biochemistry, physiology, and pharmacology. For individuals younger than the median age of 59 years, the ORs (95% CIs) associated with consuming less than 1, 1, 2 to 3, or 4 or more cups of coffee per day were 1.00, 1.24 (0.71-2.18), 1.67 (1.08-2.60), and 2.33 (1.39-3.89), respectively, among carriers of the *1F allele. Conclusions Greenland S. A meta-analysis of coffee, myocardial infarction, and coronary death. et al. All prospective cohort studies providing data on daily coffee consumption and coronary events (acute myocardial infarction and/or coronary death) were included. Some individuals have a mutation in this locus and thus have the AC genotype. NCT04330209, Registered 01/04/2020, retrospectively registered. HET mice have 2.4-fold lower baseline cortical EEG total power (EEGTP) compared to wildtype mice (WT) in the absence CAF. However, in a study of coffee intake, CYP1A2 genotype and risk of myocardial infarction coffee was associated with an increased risk of nonfatal myocardial infarction only in participants regarded as slow metabolizers of caffeine . Hammar N, Anderson T, Alfredsson L. Confounders included in the final models were smoking (never, past, 1-19 cigarettes/d, and ≥20 cigarettes/d); alcohol consumption (never, past, and tertiles of intake among current drinkers); history of diabetes (yes/no), history of hypertension (yes/no); quintiles of the continuous variables waist-hip ratio, physical activity, and income; and energy-adjusted intakes of sucrose, saturated fat, polyunsaturated fat, and trans fat. Conclusions: Measurement of coffee and caffeine intake: implications for epidemiological research. CYP1A2 genotype modifies the association between caffeine intake and risk of myocardial infarction CAF-triggered Ca2+ release and influences on skeletal muscle contractility are widely used as experimental tools to study RYR1 function/dysfunction. The present study replicated that study for 1994-1998 and found a similar preventive impact, although weak, of suicide prevention centers on the provincial suicide rates. Obesity and its related metabolic disturbances represent a huge health burden on society. measured by the rate of caffeine 3-demethylation in Japanese smokers (p<0.05). Methods: Table 2 shows the risk of MI associated with coffee intake for all participants and by CYP1A2 genotype. The metabolic profile of caffeine biotransformation by CYP1A2 averaged 81.5% for paraxanthine, 10.8% for theobromine and 5.4% for theophylline formation. The standard portion size for coffee in the FFQ was fixed as 1 cup equivalent to 250 mL, based on the habitual portion size for coffee-drinking habits established in this population during methods development.29 Participants were asked to specify 1 of 9 categories of coffee intake: none or less than 1 cup/mo, 1 to 3 cups/mo, 1 cup/wk, 2 to 4 cups/wk, 5 to 6 cups/wk, 1 cup/d, 2 to 3 cups/d, 4 to 5 cups/d, or 6 cups/d or more. Analysis and interpretation of data: Cornelis, El-Sohemy, Kabagambe, Campos. CYP1A2 genotype modifies the association between coffee intake and the risk of hypertension. Because of the comprehensive social services provided in Costa Rica, all persons living in the catchment areas had access to medical care without regard to income. Schreiber GB, Maffeo CE, Robins M, Masters MN, Bond AP. It has been suggested that the positive associations reported in case-control studies may have resulted from recall bias or confounding by factors such as smoking.19,34 However, because we observed an association between coffee and risk of MI among carriers of the *1F allele, and not among those homozygous for the *1A allele, the associations between coffee and MI are unlikely due to recall bias or residual confounding. Introduction Further epidemiological studies with consideration about characteristics of the study population are needed to determine the exact effect of coffee consumption on CVD. J-shaped or U-shaped dose-response graphs of coffee consumption and CVD parameters partially explain the inconsistency of conclusions between coffee studies on CVD, highlighting a moderate intake of coffee. Woodward M, Tunstall-Pedoe H. Coffee and tea consumption in the Scottish Heart Health Study follow up: conflicting relations with coronary risk factors, coronary disease, and all cause mortality. Eleven prospective studies were included. Coffee is a major source of caffeine, which is metabolized by the polymorphic cytochrome P450 1A2 (CYP1A2) enzyme. Controls were ineligible if they were physically or mentally unable to answer the questionnaires or if they had had a previous hospital admission related to MI or other cardiovascular disease. Relative risks (as estimated by odds ratios) and their 95% confidence intervals were computed from multiple logistic regression analyses that controlled for smoking and other risk factors.

Conclusion Intake of coffee was associated with an increased risk of nonfatal MI only among individuals with slow caffeine metabolism, suggesting that caffeine plays a role in this association. Fifty-five percent of cases (n = 1114) and 54% of controls (n = 1082) were carriers of the slow *1F allele. Ms Cornelis is a recipient of a Natural Sciences and Engineering Research Council of Canada postgraduate scholarship. Contact me when new articles are published in these topic areas. Among younger individuals who were rapid caffeine metabolizers, coffee intakes of either 1 cup/d or 2 to 3 cups/d were associated with a lower risk of MI compared with intakes of less than 1 cup/d. Corresponding ORs (95% CIs) for individuals with the rapid *1A/*1A genotype were 1.00, 0.75 (0.51-1.12), 0.78 (0.56-1.09), and 0.99 (0.66-1.48) (P = .04 for gene × coffee interaction). Relative risk of nonfatal MI associated with coffee intake, calculated using unconditional logistic regression. The increased risk associated with coffee intake was only observed … Data from each published article were extracted. However, ischemia/reperfusion-induced coronary hyperemia is believed to be mostly attributed to released adenosine, and it has been proven that adenosine attenuates the severity of ischemia due to its coronary vasodilatory action. Whether coffee consumption increases the risk of coronary heart disease has not yet been established. We evaluated the amount of green tea and coffee consumed using self-administered questionnaires. Therefore, control participants came from the source population that gave rise to the cases and are not likely to have had cardiovascular disease that was not diagnosed because of poor access to medical care. JAMA. Intake of coffee was associated with an increased risk of nonfatal MI only among individuals with slow caffeine metabolism, suggesting that caffeine plays a role in this association. To determine whether CYP1A2 genotype modifies the association between coffee consumption and risk of acute nonfatal MI. There was an interaction between TRIB1 rs17321515 and coffee consumption on CHD risk (p for interaction = 0.0330). Trial registration: Conclusions: Heavy coffee consumption was associated with a modest increase in CVD risk, but this association was unaffected by … The typical odds ratios and 95% confidence intervals across studies were estimated by logistic regression analysis.

On average, it took 27 days to complete data collection for cases and 31 days for controls. Association of boiled and filtered coffee with incidence of first nonfatal myocardial infarction: the SHEEP and the VHEEP study. It remained quite uniform when caffeine concentrations were varied. 17, 2nd ed. Because P-450IA2 is a monooxygenase that may be confined to the liver, caffeine reveals directly the Ah-receptor-dependent enzyme induction only in the liver, but it may also be a signal of induction elsewhere.

Associations between coffee drinking and increased risk of myocardial infarction(15), hypertension(16,17) and IFG(18) have been observed in individuals who are carriers of the ‘slow’ C allele but not in those with the ‘fast’ AA genotype. It has been realized recently that the primary metabolism of caffeine in humans is catalyzed by P-450IA2 and that the rate of caffeine metabolism can be estimated from a metabolic ratio in a single urine sample.

For carriers of the slow variant, the risk of incident hypertension was linearly elevated with coffee consump-tion.5 On the other hand, among rapid metabolizers, there However, it is not easy to suggest a moderate amount for the entire population concerning individual characteristics. Thus, administration of adenosine or potentiators of adenosine production in the ischemic myocardium may be beneficial for the attenuation of ischemic and reperfusion injuries, although further clinical investigations are necessary. A1 adenosine receptors, located in atrial and ventricular myocardium and sinoatrial/atrioventricular nodes, are responsible for inhibition of adenylyl cyclase activity. The answers were transformed into daily intake and compared with the recommendations of the World Health Organization (five or more servings per day). Results Fifty-five percent of cases (n = 1114) and 54% of controls (n = 1082) were carriers of the slow *1F allele.

Data on CHD were obtained from the National Health Insurance Research Database (NHIRD) while genotype data were collected from the Taiwan Biobank (TWB) Database. From the linked electronic health record data, 1116 individuals were identified with CHD while 7853 were control individuals. Genetic variation, especially CYP1A2 allele, To estimate the socioeconomic and sociodemographic factors associated with the daily intake of five servings of fruit and vegetables by elderly individuals living in low income areas, identifying the main fruits and vegetables which compose the diet of this population. Epidemiologic studies examining the association between coffee consumption and risk of myocardial infarction (MI) have been inconclusive.1-14 Coffee is a major source of caffeine (1,3,7-trimethylxanthine), which is the most widely consumed stimulant in the world and has been implicated in the development of cardiovascular diseases such as acute MI.15-17 However, coffee contains a number of other chemicals that have variable effects on the cardiovascular system.18 Because of the strong collinearity between caffeine intake and coffee consumption in many populations, it is not clear whether caffeine alone affects the risk of MI or whether other chemicals found in coffee may be responsible.
