How many doses of alcohol can prevent cardiovascular disease?

Recently, the study[1] entitled “Association between clinically recorded alcohol consumption and initial presentation of 12 cardiovascular diseases: population based cohort study using linked health records” showed that non-drinking has an increased risk of unstable angina, myocardial infarction, unheralded coronary death, heart failure , ischemic stroke, peripheral arterial disease and abdominal aortic aneurysm compared with moderate drinking. In addition, this study indicated that heavy drinking (exceeding guidelines) is associated with an increased risk of unheralded coronary death, heart failure, cardiac arrest, transient ischemic attack, ischemic stroke, intracerebral haemorrhage, and peripheral arterial disease while lowers the risk of myocardial infarction or stable angina. According to this study, alcohol in moderation can prevent cardiovascular disease, which has positive effects on the health of people. Indeed, this study has important clinical and public health implications. However, this study excluded the following patients: missing sex, age <30, <1 year follow-up before study entry, history of cardiovascular disease before entry date, pregnant within 6 months of eligibility date, so the risk of cardiovascular disease estimated in the real-world may be higher or lower. Furthermore, the specific dose of alcohol that can lower the risk of cardiovascular disease is still unclear. Thus, the specific dose of alcohol is required to need more investigations to explore.
