A study found that heart attack patients treated by less experienced physicians had lower use of evidence-based drug therapies compared to those treated by more experienced cardiologists. The researchers recommend developing new methods to standardize prescribing practices, particularly for long-practicing physicians.
Patients who received beta-blockers before and during non-cardiac surgery had higher rates of heart attack (2.94%) and death (2.52%) within 30 days compared to those who did not receive them. The study suggests that a low target preoperative heart rate is essential for the protective effect of beta-blockers.

Men who never smoke live longer and have better quality of life than heavy smokers, with an average of 10 years longer lifespan. Physical health deteriorates as the number of cigarettes smoked per day increases.
A hospital-based case-control study found that pneumococcal vaccination was associated with a 50% lower risk of heart attacks two years after vaccination. The study suggested that the pneumonia vaccine may protect against heart attacks by preventing pneumonia, which has been linked to triggering heart attacks.
A large Danish observational study found that women taking hormone replacement therapy (HRT) who used it on a cyclical basis, through skin or vaginal application, had a reduced risk of heart attacks. This contradicts previous research and suggests that certain HRT regimens may be safer than others.
