Caffeine and Cardiovascular Disease: A Scientific Statement From the American Heart Association | Circulation

Caffeine is one of the most commonly consumed drugs in the world. It is found in various naturally occurring substances and can be ingested in a synthetically derived pure form. The majority of human subject–based research is observational and has focused on beverages and foods that contain caffeine. The relationships between caffeine and cardiovascular risk factors and diseases are complex, exhibiting heterogeneity depending on the nature of the caffeine consumed and individual-level propensities. Acute versus chronic caffeine-associated cardiovascular effects are often different. Most studies suggest an inverse J-shaped relationship between consumption of naturally occurring caffeinated products and blood pressure. Data on relationships between caffeine and diabetes are not consistent, but habitual coffee consumption has been associated with a lower risk of incident type 2 diabetes. Whereas no clear relationship between caffeine and blood lipids is evident, unfiltered coffee raises low-density lipoprotein cholesterol. Caffeine, studied primarily in the context of coffee, has been shown either to have no relationship or to be associated with a lower risk of coronary artery disease and heart failure. Randomized controlled trial data among regular caffeinated coffee drinkers showed that caffeinated coffee decreases the risk of atrial fibrillation occurrence but increases the frequency of premature ventricular contractions. Data are fairly consistent that moderate caffeine consumption, again studied primarily in the setting of coffee consumption, was associated with a lower risk of stroke. Data on high doses of caffeine such as that found in energy drinks are limited and generally suggest cardiovascular harm.

Catheter-directed thrombolysis led to a lower risk of death, recurrent pulmonary embolism, or cardiorespiratory decompensation or collapse at 7 days than anticoagulation alone in intermediate-high–risk acute pulmonary embolism. Full PRAGUE-26 trial results: https://nej.md/4wyGCwb #ESCCongress

A table comparing primary outcomes of thrombolysis and standard care (death from any cause, recurrence of pulmonary embolism, or cardiorespiratory decompensation or collapse). A primary-outcome event occurred in 2
patients (0.7%) in the thrombolysis group and in 19 patients (6.8%) in the standard-care group. The relative risk was 0.10 (95% CI: 0.02–0.44).

In older adults without cardiovascular disease, treatment with atorvastatin led to a lower risk of major cardiovascular events than placebo at a median of 5.9 years but did not result in longer disability-free survival. Full STAREE trial results: https://nej.md/4ghHPSC

Graphs from the Original Article "Atorvastatin, Cardiovascular Events, and Disability-free Survival in Older Adults." The trial name, STAREE, is in parentheses after the title. The graphs show the cumulative incidence of primary end-point events (death from cardiovascular causes, nonfatal myocardial infarction or stroke, or coronary revascularization, whichever occurred first). The trial results are being presented at the European Society of Cardiology Congress 2026. The logo of the New England Journal of Medicine is at the bottom.

"Alcohol Intake and Health Study: No Protective Effect at Low Levels, With Mortality Increasing to 1 in 25 at 14 Drinks Per Week." Publié en juillet dans Journal of Studies on Alcohol and Drugs. #MedSky www.jsad.com/doi/10.15288...

Alcohol Intake and Health Study: No Protective Effect at Low Levels, With Mortality Increasing to 1 in 25 at 14 Drinks Per Week: Journal of Studies on Alcohol and Drugs: Vol 87, No 4

Objective: The purpose of this study was to estimate the lifetime risk of alcohol-attributable mortality and morbidity in the United States based on a person’s average lifetime weekly alcohol consumption to assess the impact of per-occasion alcohol consumption on health. Method: Lifetime risks were estimated using a cause-specific modeling approach that combined exposure data from national health surveys, relative risks, population data from the U.S. Census Bureau, mortality data from the Centers for Disease Control and Prevention, and morbidity data from the Institute for Health Metrics and Evaluation. A narrative review assessed the health impact of per-occasion alcohol consumption on health. Results: At low levels of consumption, no protective net effect of alcohol consumption on health was observed. Elevated mortality and morbidity risks were associated with alcohol consumption starting at relatively low levels. Males consuming >6.5 (95% CI [<1, 13.5]) and females consuming >7.0 (95% CI [<1, 11.5]) drinks per week had life-time alcohol-attributable mortality risks >1:1,000. At >8.5 (95% CI [2.5, 13]) drinks per week for both males and females, these risks increased to >1:100. At 14 drinks per week for males (the upper limit of the former Dietary Guidelines for males), the risk of an alcohol-caused death was 1:25 (4%). Drinking patterns also impacted risk. Above 1 drink per occasion, higher consumption was associated with progressively increased risks of breast cancer, cardiovascular disease, and injury. Conclusions: Alcohol consumption, including at what may be perceived as “moderate” levels, is associated with increased mortality and morbidity risks. These results support tightening alcohol use guidance in the United States, for both males and females, to no more than 1 drink per day. Public health significance statement: The Alcohol Intake and Health Study shows that for Americans, even what is socially considered “moderate drinking” increases the risk of dying or developing health problems, helping people better understand the net health impact of alcohol. Furthermore, by identifying the levels of alcohol use that raise the risk of cancer, cardiovascular disease, and injury, these findings can guide individuals, families, and communities in making safer choices about drinking patterns. The results also support changing the U.S. Dietary Guidelines on alcohol to recommend that current adult drinkers consume 1 drink or less in a day.
