title: Clinical profile of acute myocardial infarction in elderly (prospective study).
abstract: BACKGROUND
  Heart disease is the leading cause of hospitalization and death in elderly patients. The role of conventional cardiovascular risk factors in older persons is incompletely understood because only fragmentary and inadequate data are available in most instances and the manifestations of acute myocardial infarction are generally believed to be atypical in the elderly.
  
  
  OBJECTIVE
  The purpose of this study is to describe the risk factors, clinical features, outcomes in AMI in Elderly (>60 years) and to compare the same with the young subjects (<60 years) and to study the various complications in 30 days follow up.
  
  
  METHODS
  Prospective observational cross- sectional analytical study.
  
  
  METHODS
  ICCU Department of Medicine, Indira Gandhi Government Medical College, Nagpur.
  
  
  METHODS
  120 cases of AMI were categorized in two groups:--(a) Group I--age < 60 years, (b) Group II--age >60 years. Subjects were analyzed for baseline clinical history, complications, and risk factors of AMI. A detailed clinical examination and relevant investigations were done. The various complications at the time of admission were recorded. 07 days in hospital follow up and 30 days follow up after discharge from hospital was done for various complications.
  
  
  RESULTS
  The male and female ratio was 3:1 in group I and 1.37:1 in-group II Atypical chest pain, sweating, dyspnoea and giddiness were observed predominantly in the elderly group with AMI than younger group, and less no. Of elderly subjects arrived at hospital within 6 hours of chest pain as compared to young subjects. (30/64 i.e. 46.8% vs. 40/56 i.e. 71.4%, p = < 0.05). Thrombolytic therapy and beta-blockers were under used in elderly (group II) (35.8% & 7.8% cases) as compared to( 60.8% and 60.8% cases) in(group I) respectively. Poor LVEF <55% (31 i.e. 63.2% cases) and presence of ventricular aneurysm in 2 cases were observed in-group II (>60 years). The incidence of major complications like congestive cardiac failure, arrhythmias, AV block were significantly higher in the elderly group (70.2%, 57.8%, 28.6%) as compared to (46.5%, 37.5%, 7.1%) respectively in younger group. Mortality, CCF, post AMI angina were the common complications observed in group (II), during one month follow up after AMI, whereas interventions like CABG/ PTCA were commonly performed in group I (<60 y). Mortality was significantly high in elderly group (II) than young (gr I) with AMI, 25 (39%) vs. 7 (12.5%) (p = 0.019).
  
  
  CONCLUSIONS
  We conclude that the manifestations of AMI are more subtle in the elderly, with different risk factors. The elderly subjects are under thrombolysed and have higher complication and mortality rate.
