[A year follow-up of 328 patients with myocardial infarction]
Insights
This study followed 328 acute myocardial infarction patients for one year, finding an 81.4% survival rate and reduced mortality. Many patients experienced complications, but a significant portion returned to professional activity.
Area of Science:
- Cardiology
- Clinical Medicine
- Public Health
Context:
- Acute myocardial infarction (AMI) remains a leading cause of mortality and morbidity worldwide.
- Understanding patient outcomes and treatment effectiveness is crucial for improving cardiac care.
- This study examines a cohort of AMI patients admitted over a two-year period.
Purpose:
- To evaluate the one-year outcomes, including survival rates, complications, and functional status, of patients admitted for acute myocardial infarction.
- To assess the impact of early interventions such as thrombolysis and angioplasty on patient recovery.
- To analyze the long-term effects of AMI on patients' quality of life and return to professional activity.
Summary:
- A cohort of 328 acute myocardial infarction patients (average age 63.5 years) were followed for one year.
- Hospital mortality was 10.4%, with 48% experiencing complications. Interventions included primary thrombolysis (38%), primary angioplasty (9%), and coronary angiography (74%).
- One-year survival was 81.4%, with 52.6% asymptomatic, 31% showing cardiac failure, and 18% with residual angina. 61.4% of active subjects returned to full-time work.
Impact:
- The findings highlight the significant morbidity and mortality associated with acute myocardial infarction, despite advancements in treatment.
- The study suggests a continuous reduction in infarct-related mortality and morbidity by 1992, indicating the effectiveness of evolving medical strategies.
- Improved patient outcomes and functional recovery are achievable, with a substantial proportion of patients returning to their professional activities.
Abstract:
Three hundred and twenty eight patients (238 men, 90 women) with an average age of 63.5 +/- 18 years admitted consecutively for acute myocardial infarction over a 24 month period (March 1989-March 1991) were followed up at one year by out-patient appointment, questionnaire or telephonic enquiry. The average delay before hospital admission was 6.7 +/- 44 hours (1 h-48 h). The infarct was transmural in 82% of cases, anterior in 45.3%, inferior in 46.3% and lateral in 8.4% of cases. Forty eight per cent had one or several complications during the hospital period with a 10.4% hospital mortality rate. Thirty eight per cent of patients underwent primary thrombolysis and 9% had primary angioplasty. Seventy four per cent of patients had coronary angiography; 41% underwent deferred angioplasty and 6% surgical revascularisation. The global 1 year survival rate was 81.4%. At follow-up, 52.6% of patients were asymptomatic, 31% had signs of cardiac failure and 18% had residual angina. Sixty five per cent were treated with 2 or 3 drugs; 6% underwent secondary angioplasty and 2.8% secondary coronary bypass surgery. Of the 34% of active subjects, 61.4% declared having returned to full-time professional activity. Therefore, in 1992, a continuous reduction of infarct-related mortality and morbidity was observed.
