New Delhi, Nov 14 (ANI): Have you had a heart attack or a stroke recently? Monitor your cholesterol regularly. A recent study has suggested, patients who don't follow up by getting a cholesterol test following a heart attack or a stroke are significantly more likely to have another serious cardiovascular episode. Doctors have suggested that if you have a heart attack or stroke, it's important to get your low-density lipoprotein (LDL) cholesterol popularly known as "bad" cholesterol measured by an expert on a follow up visit as it is the main source of clogging arteries, thus making heart attacks and strokes more likely. The study was conducted on more than 60,000 patients with average age of 66 years old suffering from known heart disease, cerebrovascular disease or peripheral artery disease, and results showed the major adverse clinical event rate was lower in both patients who took cholesterol-lowering drugs and those who didn't if their LDL was measured. Researchers found the risk of a patient having a secondary event or dying decreased in those who had a follow-up LDL test before a subsequent adverse outcome or before the end of their follow-up.
