Abstract

Abstract: Background and Aims: Hypertension is the leading entity of non communicable diseases (NCD). Some 15-30% adult population is identified suffering from hypertension at any given time worldwide. Complications of hypertension cause severe functional deficit and a major decline in quality of life for the patient and family. This study was carried out to identify the presence and pattern of cardiac and renal risk factors influencing major morbidity and mortality in hypertensive subject by performing relevant clinical and laboratory evaluations. Method: In this survey adult subjects were selected randomly from a defined rural area. Their demographic, anthropometric and clinical information was recorded by WHO STEP wise approach surveillance-Instrument v.3.1. Information on prevailing NCDs and related risk factor were collected on a short questionnaire by face-to-face interview. Blood Pressure (BP) was measured by digital blood pressure monitor (Omron) with standard sized cuff after 10-15 minutes of rest in sitting posture by taking mean of two readings. Systolic BP ≥140 and/or diastolic BP ≥90mmHg or subjects taking antihypertensive medications were considered for hypertension. Early morning urine and fasting blood sample was collected for glycemic profile, lipid profile, serum creatinine, eGFR (MDRD equation) and urine ACR estimations for identifying diabetes, dyslipidemia and nephropathy. Results from an early group are presented here. Results: From surveyed population consequative 300 hypertensive subjects with 100 normotensive subjects were analyzed. Male/female distribution was 66% and 34%. Age in 75% was between 25-55 years and BMI overweight to obese in 45%. Etiology wise in 81% it was essential hypertension followed by diabetes 18% and nephropathies in rest. Mean systolic BP was 147±16 and diastolic BP 71±9 mmHg. Comparison of hypertensive vs. normotensives showed FBS 6.7±3 vs. 5.8±1.0 mmol/l, (p<0.001). Lipids as cardiac markers were TG 170±107 vs. 130±76 g/dl, (p<0.001); Cholesterol 195±50 vs. 180±49 g/dl, (p<0.001); LDL 170±107 vs. 130±76 g/dl, (p<0.04); and HDL 42±7 vs. 46±8 g/dl, (p<0.001). Renal parameters like eGFR was 88±22 vs. 98±26 ml/min, (p<0.001); and ACR 99±556 vs. 30±87 mg/g, (p<0.04). These comparisons showed fasting hyperglycemia with most of the lipids higher and HDL lower in hypertensives. Renal parameters like eGFR was lower and albuminuria was significantly higher with similar urinary Na and K excretion in hypertensives. Other cardio renal markers like Uric Acid and hCRP was similar in both groups. Pearson's correlations showed a positive correlation of systolic and diastolic BP with major components of cardiac, renal and metabolic risk factors. Conclusion: It is found that hypertension is essential in nature among 81% of rural subjects. Nearly half of the study subjects are overweight. Dyslipidemia, albuminuria and low GFR is more pronounced in hypertensives in comparison to the normotensive counterparts. So, hypertension is mostly associated with adverse cardio-renal risk markers.
