The single most important step is to get the patient to stop smoking cigarettes. Cigarette smoking can wipe out all of the gains you receive from using statins such as rosuvastatin and/or the PCSK-9 inhibitors. The trick is to get to the LDL-c goal that will stabilize/regress and subclinical (or, heaven forbid), clinical atherothrombotic plaque. Treating hypertension is a must, as is treating diabetes--but the real bang for the buck lies with cigarettes and lipids.
Most effective measure to prevent Ischaemic heart disease is Life style modification , regular interval lipid profile test, regular exercise , good control of BP and Blood sugar
Dr Bharti, I must disagree most strongly with you--unless you mean in low risk groups only. That would NOT include cigarette smokers. The single most important therapeutic measure for the prevention of atherothrombotic disease (ATD) is the cessation of cigarette smoking, which of course would be a lifestyle change. What is necessary for primary prevention of ATD is the optimization of lipids and blood pressure, and it is hard to do that with simple life style changes. Statins are almost always required to achieve lipid goals and anti-hypertensive agents for hypertension. Most younger ATD patients do not have diabetes and those that do almost always have lipid and/or blood pressure abnormalities.
