[Lipid lowering treatment in secondary prevention following myocardial infarct]
Insights
This study on myocardial infarction patients found high lipid levels, especially LDL-C, in those with early onset. It highlights the need for aggressive lipid-lowering treatment and secondary prevention strategies post-myocardial infarction.
Area of Science:
- Cardiology
- Lipid Metabolism
- Public Health
Context:
- Retrospective analysis of 1081 myocardial infarction patients (1990-1995).
- Investigated early vs. late myocardial infarction demographics and risk factors.
- Focused on lipid profiles due to high prevalence of hyperlipoproteinemia (83.3%).
Purpose:
- To analyze lipid parameters in patients with early myocardial infarction.
- To compare patient lipid levels against secondary prevention targets.
- To emphasize the importance of secondary prevention and lipid-lowering therapies.
Summary:
- Early myocardial infarction patients exhibited high cholesterol (mean 6.91 mmol/l) and LDL-C (mean 4.71 mmol/l).
- Few male patients met cholesterol or LDL-C targets; female patients had higher LDL-C than recommended.
- A significant percentage of male patients had optimal HDL-C (>1.1 mmol/l), but triglyceride levels varied.
Impact:
- Underscores the critical need for enhanced secondary prevention strategies in post-myocardial infarction patients.
- Advocates for broader implementation of lipid-lowering treatments to improve outcomes.
- Suggests a potential gap in current lipid management protocols for myocardial infarction survivors.
Abstract:
1081 patients treated with myocardial infarction between 1990-1995 were investigated retrospectively, 652 (60.3%) of the patients were male and 429 (39.7%) were female. 154 (14.2%) patients had an early, while 927 (85.5%) patients had late myocardial infarction. Of the patients with early myocardial infarction 52.3% were smokers, 45.2% had positive family history for ischaemic heart disease or acute myocardial infarction. The lipid parameters were analysed in detail, because 83.3% of the patients were hyperlipoproteinaemic. The mean cholesterol level was 6.91 +/- 1.2 mmol/l, the HDL-C level was 1.19 +/- 0.38 mmol/l, the triglyceride level was 2.66 +/- 1.8 mmol/l, the LDL-C level was 4.71 +/- 1.2 mmol/l. The serum LDL-C and the HDL-C levels of the patients with early myocardial infarction were compared to the desirable levels suggested for secondary prevention. Only 7.2% of the male patients had a cholesterol level below 5.2 mmol/l, while all female patients cholesterol levels were above 5.2 mmol/l. Of the male patients 53.6%, while 78.6% of females had lower triglyceride levels than 2.3 mmol/l 78,6% of the male patients had higher protective HDL-C level in the optimal range (> 1.1 mmol/l). 12.5 percent of the male patients had an LDL-C level lower than the value targeted by secondary prevention (3.0 mmol/l), while all of the female patients LDL-C levels were higher. The authors emphasize the importance of secondary prevention and a more widespread use of lipid lowering treatment for patients after acute myocardial infarction.
