Acute Myocardial Infarction in Rats
Published on: February 16, 2011
[Heart rupture in myocardial infarction]
Insights
Ischaemic heart disease (IHD) and acute myocardial infarction (AMI) were more common in adults over 60, with women affected later than men. Mortality from IHD and AMI declined, while heart rupture mortality remained stable.
Area of Science:
- Cardiology
- Pathology
- Public Health
Context:
- Analysis of mortality data from Dr. Josip Kajfes General Hospital in Zagreb spanning 1972-1986.
- Inclusion of 4,459 post-mortem examinations from 8,589 deceased adult patients.
- Focus on cases consistent with ischaemic heart disease (IHD).
Purpose:
- To investigate the incidence and characteristics of ischaemic heart disease (IHD), including acute myocardial infarction (AMI) and heart rupture (HR).
- To analyze demographic differences, particularly age and sex, in IHD, AMI, and HR occurrences.
- To assess trends in mortality rates for IHD, AMI, and HR over a 15-year period.
Summary:
- A total of 496 IHD cases were identified, with 322 diagnosed as AMI and 64 as heart rupture (HR).
- IHD and AMI were more prevalent in individuals over 60, with women experiencing these conditions approximately six years later than men.
- The anterior wall of the left ventricle was the most frequent site for both AMI and HR. Heart rupture typically occurred around 3.46 days post-AMI, with a delay in women.
- Mortality rates for IHD and AMI showed a decline over the study period, whereas HR mortality remained relatively constant.
Impact:
- Provides insights into the epidemiological patterns of IHD, AMI, and HR in a specific population.
- Highlights age and sex disparities in the manifestation and timing of these cardiac events.
- Demonstrates changing mortality trends for different manifestations of ischaemic heart disease over a significant period.
Abstract:
During the period 1972-1986. 8.589 adult patients died at the Dr. Josip Kajfes General Hospital in Zagreb. Post mortem examinations were performed in 4.459 patients and 496 cases discovered, which were in keeping with so-called ischaemic heart disease (IHD). Acute myocardial infarction (AMI) was found in 322 patients and rupture of the heart (HR) in 64 patients. According to our results IHD and AMI occurred more frequently in persons over 60 years of age, but women were affected on the average some 6 years later than men in all three groups of test subjects. The anterior wall of the left ventricle was the most common site of both AMI and HR. Heart rupture occurred on the average some 3 days after an attack of AMI (average 3.46 days) but this was seen in women a whole day later than in men. The results obtained showed moreover that the mortality rate in patients who died from IHD and AMI over the analysed 15-year period registered a decline, while the mortality rate of patients who died of HR in the same period remained more or less unchanged.
