Cannabis Users Face Substantially Higher Risk of Heart Attack (2025)
16 days ago
- Cannabis users under 50 face over sixfold increased heart attack risk vs. non-users
- Meta-analysis shows 50% higher heart attack risk for cannabis users
- Studies also link cannabis use to increased stroke, heart failure, and cardiovascular death
- Researchers urge clinicians to screen for cannabis use in cardiovascular risk assessment
- Potential mechanisms include heart rhythm disruption and endothelial dysfunction
- Retrospective study and meta-analysis limitations call for prospective research
- Risk peaks about one hour after cannabis consumption
- Daily marijuana use previously linked to higher coronary artery disease risk
Graham's death from aortic dissection raises questions about prevention
5 days ago
- Sen. Lindsey Graham's death from aortic dissection at 71 highlights the condition's severity and sudden onset.
- Experts question if prior imaging might have detected aortic dilation, emphasizing that dissection often has a long prelude.
- Aortic dissection is more common in men aged 50s-60s, with risk factors like high blood pressure and atherosclerosis.
- Current risk prediction relies heavily on aortic diameter, but many dissections occur below surgical thresholds.
- AI and advanced imaging may improve risk prediction by analyzing aortic shape, wall characteristics, and biomechanics.
- Family history is a crucial risk factor, with about 20% of patients having a first-degree relative with similar disease.
- Genetic syndromes like Marfan syndrome increase vulnerability, though they are rarer.
- Aortic dissections cause 3.5 per 100,000 deaths globally, with smoking, hypertension, and high BMI as top risks.
- Once an aortic dissection occurs, it is a surgical emergency requiring immediate intervention.
- Public awareness is key: treat symptoms as a medical emergency by calling 911 for early diagnosis and improved survival.
5 Cups of coffee per day (up to 400 mg of caffeine/day) is safe for most adults
19 hours ago
- Consuming up to 400 mg of caffeine per day (about 5 cups of coffee) is generally safe for most adults and may lower risks of heart disease, stroke, and heart failure.
- High caffeine doses from energy drinks (shots) can increase risks of high blood pressure and irregular heart rhythms.
- Coffee's health benefits may come from bioactive compounds, but adding sugar, milk, or cream can reduce these benefits.
- Caffeine effects vary by individual due to genetics, metabolism, age, and tolerance, so personalized intake is recommended.
- More research is needed on different caffeine sources and their specific impacts on cardiovascular health.
