MICROALBUMINURIA IN NEWLY DIAGNOSED HYPERTENSIVE PATIENTS AND ITS CORRELATION WITH LEFT VENTRICULAR HYPERTROPHY”

Abstract

Background: One of the most important factors in the development of cardiovascular diseases worldwide is Hypertension. A reliable indicator and a diagnostic modality in early stage of renal diseases and predictor of atrial hypertension (AH) progression is microalbminurea (MAU) which is also an independent risk factor of cardiovascular mortality and death. Objective: To determine the prevalence of microalbuminuria and left vertricular hypertrophy and assess correlation between micro albuminuria and LVH among newly diagnosed hypertensive patients. Methods: A cross sectional study conducted in Medical Unit IV, Jinnah Hospial Lahore from January to June, 2022. About 146 adults newly diagnosed hypertensive patients were included for study. Blood pressure was measured using sphygmomanometer with standard cuff in sitting position, with two measurements were made at least 5 min apart. Microalbuminuria was defined as albumin excretion 30 to 300 mg/dl in a spot urine sample report. Left ventricular hypertrophy (LVH) is defined as presence of concentric hypertrophy or diastolic dysfunction determined on Trans Thoracic ECHO by a cardiologist. Data was entered in SPSS Ver: 25.0 for data analysis and graphical presentation. For quantitative variables like age, ACR; mean and standard deviation was calculated. Prevalence and correlation of MAU and LVH in newly diagnosed hypertensive patients was using Spearmen’s Rank Correlation Analysis. Chi-square test was performed to compare MAU and LVH. P-value of < 0.05 was considered statistically significant. Results: 146 subjects those fulfilling the inclusion criteria were admitted. Mean age was 48.281 + 24.865. 72.6% were male in our study. 30.8% of patients had LVH and microbuminurea was present in 47.5% of subject. About 28.6% of patient with LVH had MAU. (p=.030). There was a positive correlation between LVH and MAU. (r=0.135, P =.002). Conclusions: Our study concludes a high prevalence of micro albuminuria and LVH in newly diagnosed hypertensive. There is positive correlation between micro albuminuria and LVH and can be predictor of cardiovascular morbidity and mortality.
