  1. *represents fever and diarrhea
  2. SBP systolic blood pressure, DBP diastolic blood pressure, Cholesterol > 5.2 mmol/l was raised, triglyceride > 1.69 mmol/l raised, hdl < 1.04 mmol/l low, ldl 3.4 mmol//l raised were identified as dyslipidemia. Reduced ejection fraction was defined as EF < 50%, normal ≥50%, LVH on echocardiography was seen if IVSD was ≥12 mm, dilated left atrial diameter > 40 mm
