Blood pressure of 120/110 can be diagnosed as hypertension. Your blood pressure is high, especially diastolic pressure. Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease (CAD), stroke, peripheral artery disease and chronic renal failure. You can improve your lifestyle by eating a low-salt diet, stopping smoking and restricting alcohol, and losing weight, and exercising moderately. In the meantime, you should use some antihypertensive drugs which should be administered under the direction of a cardiologist, such as Angiotensin-converting enzyme inhibitor, Angiotensin receptor blocker, β-Blocker, Dihydropyridine calcium channel blocker, Thiazide diuretic.
