smoking,lousy diet i.e too much saturated fat,drinking to excess,lack of exercise,familial link,bad genes. signs of CHD are obesity,high blood pressure,,breathlessness on slight exertion,poor stress tolerance results(treadmill ),changes on ECG,raised cholesterol levels.CHD is one of the biggest killers in the western world after lung cancers and respiratory illnesses and despite it being relatively easily resolved with dietary alteration and moderate exercise 3 times a week,the western world with its love of fast/processed foods still refuses to amend the lifestyle and drop the risk!!!treatments include referral to dieticians ,uptake of exercise,smoking cessation groups,use of statins daily to reduce cholesterol levels,reduction of dietary salt and a more drastic approach is to insert balloon stents into the coronary arteries to maintain blood flow to the heart.artherosclerosis is the furring up of the artery walls with plaque like deposits of fat,reducing the blood flow to the heart muscle,in turn causing fibrillation of the chamber/s and subsequent death of the heart muscle=myocardial infarction(heart attack) or cardiac arrest= heart stopping.
