Efficacy of high dose Allopurinol in reducing left ventricular mass in patients with left ventricular hypertrophy by comparing its efficacy with Febuxostat - a randomized controlled trial.

: To determine the efficacy of high-dose allopurinol in reducing left ventricular mass in patients with left ventricular hypertrophy by comparing its efficacy with febuxostat..The randomised controlled interventional study was conducted at Mayo Hospital, Lahore, Pakistan, from April to December 2015, comprising patients with left ventricular hypertrophy on echocardiography. They were randomly divided into two equal groups, with Group A receiving allopurinol and Group B receiving febuxostat. Primary endpoint was reduction in left ventricular mass and left ventricular mass index as calculated by echocardiography. Patients were followed at third and sixth month of enrolment to detect regression. Patients were investigated for eosinophil's count, urine for micro albuminuria and renal function tests to monitor side effects of allopurinol. SPSS 20 was used for data analysis.There were 76 patients divided into two groups of 38(50%) each. Mean reduction in left ventricular mass between baseline and at six months in Group A and Group B was 35.474±13.54 and 21.921±3.33 respectively (p=0.0001) while mean reduction in left ventricular mass index between baseline and at six months was 17.26±4.36 and 17.63±21.07 respectively (p=0.0001). Greater improvement was observed in Group A..Allopurinol was found to be more effective than febuxostatin reducing the left ventricular mass and left ventricular hypertrophy independent of blood pressure.
