Triglycerid level as a potential marker of residual cardiovascular risk and its relation to HeartScore.
BACKGROUND Atherosclerotic cardiovascular diseases (ASCVD) are still the leading cause of morbidity and mortality in Bosnia and Herzegovina. Elevated LDL-cholesterol is established as a strong marker of cardiovascular risk. Some researchers believe that measuring triglyceride levels gives a good assessment of the residual risk for ASCVD besides the measurement of LDL-cholesterol. OBJECTIVE The aim of this study was to evaluate the overall prevalence of major risk factors for ASCVD, lipid profile and 10-year fatal cardiovascular risk using the HeartSCORE scoring system. Further we want to evaluate the prevalence and relationship between elevated triglyceride levels and high 10-year fatal cardiovascular risk calculated as a HeartSCORE. METHODS This is a cross-sectional study conducted on 832 volunteers aged between 40 and 65 years without a diagnosis of diabetes and without known preexisting cardiovascular disease, as a part of the preventive program conducted at the Familly Medicine office. Data were collected for ASCVD risk factors and lipid panel (total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides). 10-year fatal cardiovascular risk was calculated using the HeartSCORE scoring system for countries with high CV risk. RESULTS Among 832 participants included, 565 (67.9%) were female, and 267 (32.1%) were male. We found high prevalence of hypertension (27.7%), obesity (32.2%), and smoking (36.2%). All lipid parameters, except HDL-C, were not optimal. Only 17.4% of participants had normal estimated HeartSCORE risk, while more than one-third (33.9%) had high or very high estimated HeartSCORE risk. Although we found a higher percentage of participants with elevated triglycerides in groups with higher HeartScore, there was a very weak positive correlation between values of triglycerides and the 10-year risk of a fatal cardiovascular event (r= 0.249, p= 0.000). CONCLUSION High prevalence of major known risk factors and high estimated HeartSCORE risk indicate a high overall risk for ASCVD in the sample. The proportion of participants with elevated triglycerides was increased in patients with high HeartSCORE risk what implicates importance of trygliceride measurement.
