Look for other components of metabolic syndrome and complications of both diabetes and hypertension. If this fails to control the blood pressure, monotherapy should be commenced and if unsuccessful, combination therapy will be required to achieve the target blood pressure level. Two major processes lead to cardiovascular disease: atherosclerosis and hypertension. The clinical spectrum of cardiovascular disease is: a) Coronary heart disease: Angina (which may be silent). However, contraindications may prevent its use, especially the presence or history of peptic ulcers, dyspepsia, heartburn or bleeding and asthma. Aspirin should not be used in uncontrolled and malignant hypertension of more than 160/100 mmHg.
