[Retrospective evaluation of angina pectoris in patients with primary and recurrent myocardial infarct]
Insights
Angina pectoris and a preinfarction state are common in first-time and recurrent myocardial infarction (MI) patients. Medical advice was sought more often during angina exacerbation in those with prior MI history.
Area of Science:
- Cardiology
- Clinical Medicine
Context:
- Retrospective analysis of 283 myocardial infarction (MI) patients.
- Investigated the prevalence of anginose pain, angina pectoris exacerbation, and preinfarction states in relation to MI history.
Purpose:
- To analyze the clinical characteristics and preceding symptoms of myocardial infarction.
- To understand the patterns of anginose pain and medical consultation in patients with primary and recurrent MI.
Summary:
- A significant majority of MI patients, both first-time (64.7%) and recurrent (88.6%), reported a history of anginose pain.
- Angina pectoris exacerbation was noted in 56.0% of new MI cases and 71.4% of recurrent MI cases.
- A preinfarction state was observed with similar frequency in primary (73.0%) and recurrent (74.7%) MI.
- Nitroglycerin efficacy decreased in the month before MI.
- Patients with prior MI history were more likely to seek medical advice during angina exacerbation (73.8%) compared to first-time MI patients (39.8%).
Impact:
- Highlights the importance of recognizing anginose pain and preinfarction states as critical indicators for myocardial infarction.
- Suggests a need for heightened vigilance and timely intervention in patients experiencing angina, particularly those with a history of cardiovascular disease.
- Informs clinical practice regarding patient monitoring and management strategies for individuals at risk of or experiencing myocardial infarction.
Abstract:
Retrospective analysis of information on 283 patients with myocardial infarction (186 males and 97 females) showed that 64.7% of persons who had suffered from the disease for the first time and 88.6% of those with recurrent myocardial infarction had a history of anginose pain. Exacerbation of angina pectoris had occurred in 56.0% of patients with no previous myocardial infarction and in 71,4% of those with recurrent infarction. A preinfarction state was encountered in primary and recurrent myocardial infarction with equal frequency (in 73.0 and 74.7% of cases, respectively). Nitroglycerin efficacy diminishes in the month preceding myocardial infarction. During exacerbation of angina pectoris, 39.8% of patients who had no previous myocardial infarction and 73.8% of those with a history of the disease applied for medical advice.
