Your symptoms are suggestive of heart failure secondary to ischemic changes in the heart. I advise you to get an ECG,2 D Echo, lipid profile, hsCRP immediately to confirm the diagnosis. Monitor your blood pressure regularly. Take fluids 3-4 liters per day. If blood pressure is less than 8060 mm Hg you may need intravenous fluids. Chat Doctor. Coronary angiogram with or without stenting will be the procedure of choice. Consult your cardiologist for expert management.
