Comparison of cardiovascular disease patterns in two data sets of patients admitted at a tertiary care public hospital in karachi five years apart

ABSTRACT

To compare the disease patterns in two data sets of patients, five years apart, at the National Institute of Cardiovascular Diseases [NICVD], a tertiary care cardiac hospital in Karachi. The underlying objective was to determine any changes in cardiovascular disease patterns at an acute cardiac unit over a period of five years. A retrospective descriptive study was conducted on patients admitted in West Ward, National Institute of Cardiovascular Diseases [NICVD], Karachi in September, 2000 and September, 2005. Patient's record files were reviewed and the relevant information was recorded on a pro forma designed for the purpose. In September, 2000, a total of 414 patients were admitted. Of these 71.25% were males. Majority of patients [72.92%] were in the fifth decade of life or beyond. Acute coronary syndrome [ACS] was the commonest presentation, present in 39.8% of the patients. 27.3% had myocardial infarction [MI] while 10.34% were diagnosed with heart muscle diseases. The overall mortality was 3.4%. In September, 2005, a total of 446 patients were admitted. Of these, 63% were males. 71 .29% were in the fifth, sixth, and seventh decades of Life. 43.04% patients were admitted with acute coronary syndromes [ACS], 26% with myocardial infarction [MI] and 13.45% with heart muscle diseases. The overall mortality was 1.34%.The almost similar results in two. data sets of patients five years apart suggests that the cardiovascular disease burden and pattern has not changed significantly at this center. There is a preponderance of cardiovascular illnesses in males and older age groups. ACS and MI account for majority of admissions
