Mondays May Elevate Your Risk of Serious Heart Attacks

According to a recent study at the British Cardiovascular Society conference, individuals are more prone to experience severe heart attacks on Mondays than on any other day of the week. The research, conducted by doctors at the Belfast Health and Social Care Trust and the Royal College of Surgeons in Ireland, involved studying over 20,000 patients.

The findings indicated that patients were more likely to suffer from ST-segment elevation myocardial infarction (STEMI) on Mondays, one of the most severe types of heart attacks. STEMI occurs when a major coronary artery becomes completely blocked, disrupting oxygen and blood supply to the heart.

Dr. Jack Laffan, the lead researcher at the Belfast Health and Social Care Trust, stated that the exact reasons behind these variations in heart attacks are unknown. However, previous studies have suggested that circadian rhythms and hormonal fluctuations may play a role. Dr. Laffan also attributed the increased risk on Mondays to the stress associated with returning to work, which can elevate levels of the stress hormone cortisol and contribute to a higher risk of heart attacks.

STEMI differs from other types of heart attacks, as it involves a complete blockage of the coronary artery, while other heart attacks typically entail partial blockages. Risk factors for STEMI include tobacco use, smoking, diabetes, high cholesterol, excessive alcohol consumption, drug use (such as amphetamines and cocaine), and a sedentary lifestyle. A family history of heart disease can also increase the likelihood of developing STEMI.
