INTRODUCTION: Hypertensive emergency is defined as severe hypertension more than 220/140mm hg with end organ damage. A number of cardiovascular, pulmonary and neurological symptoms are found to be associated with patients in hypertensive emergency with target organ involvement. Focal neurological deficit, intracranial bleed, non–haemorrhagic infarct, acute myocardial infarct, progressive renal failure, headache being commonest symptoms. The goal of treatment is to reduce BP<25% in 2–6 hrs stabilised to 160/100 mm hg then 25% with in 48hrs. DURATION OF STUDY: September 2018 – December 2019 SAMPLE SIZE :125 cases of hypertensive emergencies during entire duration of study. AIMS AND OBJECTIVES: To study the complications of hypertensive emergencies related to cardiovascular, renovascular and neurological system. METHODOLOGY: Prospective observational descriptive study. DISCUSSION: Research intended for clinical study of complications of hypertensive emergencies. Most common presentation include stroke (intracranial bleed or non–haemorrhagic infarct), hypertensive heart failure, acute myocardial infarction, progressive renal insufficiency, left ventricular failure. RESULTS: Study is conducted on 125 patients. Most common complication of hypertensive emergencies is intracranial bleed (32%) followed by non–haemorrhagic infarct (20.8%). Hypertensive heart failure accounts for 12%, progressive renal failure accounts for 13.6%, acute myocardial infarction accounts for 1.6%. CONCLUSION: Study concluded that non–haemorrhagic infarct is the most common complication of hypertensive emergencies followed by intracranial bleed, TIA.
