Tendência temporal de letalidade hospitalar por infarto agudo do miocárdio: 1994-2003

Abstract

There was a decrease in lethality and the change of behavior in the treatment of AMI along the years was responsible for the reduction of lethality in that temporal series.

Maior letalidade e morbidade por infarto agudo do miocárdio em hospital público, em Feira de Santana - Bahia

“…The mortality and morbidity from AMI depends on factors related to the severity of the disease and the speed and quality of hospital care. If the patient receives appropriate hospital care within few hours after onset of the symptoms, the mortality worldwide is around 10% 2, similar to that observed in the hospitals of the cities of Rio de Janeiro (10.8%) and Niterói (12.3%) 3,4 . However, this percentage may not reflect the reality when there are factors such as delay between the onset of pain and arrival at the hospital, delay in the start of in-hospital treatment, restrictions on the use of myocardial protection measures, such as primary angioplasty and thrombolytics, and on access to intensive care unit 2,5 .…”

Escore TIMI no infarto agudo do miocárdio conforme níveis de estratificação de prognóstico

“…The in-hospital mortality rate among unselected patients with AMI ranged from 10 to 20% 18 . The mortality rate of 17.5% found in this sample was similar to that found in other Brazilian [4][5][6]19 and international studies (12.6%) 10 . These values are quite different from the value of 6.1% found in randomized clinical trials, such as the TIMI study 9 .…”

“…The prevalence of elevated blood pressure (61.2%) was similar to that found in Brazilian studies [4][5][6]15 and higher than that found in international studies (21.6% 9 and 54% 10 ).…”

“…In recent decades, the establishment of coronary units, the widespread use of fibrinolytic, beta blockers, aspirin and the development of transluminal coronary angioplasty contributed to reduce the rate of hospital mortality after AMI, from 30% in the 50's to the current 6 to 10% [3][4][5] . However, the variability in mortality is considerable and it is related to differences in the seriousness of the conditions and the quality of medical care [3][4][5][6] .…”
