In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without these genetic associations. Differences in blood LDL cholesterol and systolic blood pressure (the highest level that blood pressure reaches when the heart contracts), along with the number of cardiovascular events was compared between groups. A long-term reduction of 1 mmol/L low-density lipoprotein (LDL), or 'bad' cholesterol, in the blood with a 10 mmHg reduction in blood pressure led to an 80 percent lower lifetime risk of developing heart and circulatory disease. This combination also reduced the risk of death from these conditions by 67 percent. The team found that even small reductions can provide health benefits. A decrease of 0.3 mmol/L LDL cholesterol in the blood and 3 mmHg lower blood pressure was associated with a 50 percent lower lifetime risk of heart and circulatory disease. Association of Genetic Variants Related to Combined Expos...
