The most important risk factors for myocardial infarction include among other things, cholesterol (including LDL and HDL) and neutral fats - triglycerides. The aim of the research was the analysis of the levels of biochemical parameters in patients after myocardial infarction and without it on the risk of myocardial infarction. The study was conducted among patients suffering from ischemic heart disease, treated in five randomly selected primary healthcare facilities in Lublin. The study revealed that among patients with high levels of lipids (total cholesterol, LDL cholesterol, and triglycerides) the myocardial infarction is significantly more often observed, although there is a weak but statistically significant correlation between the level of triglycerides and HDL cholesterol concentration. Higher levels of triglycerides are accompanied by lower levels of HDL cholesterol. The variables having a statistically significant impact on the risk of heart attack are elevated levels of total cholesterol and low HDL cholesterol levels. High total cholesterol on average increases the risk of heart attack 3-fold compared to patients whose cholesterol level is normal. Patients with low levels of HDL cholesterol on average have a 2-fold higher risk of myocardial infarction as compared to patients whose concentration is higher than 35 mg%.
