[Prinzmetal angina: clinical aspects and coronarographic findings]
Insights
Prinzmetal
Area of Science:
- Cardiology
- Vascular Medicine
Context:
- Prinzmetal's variant angina pectoris is a clinical syndrome characterized by chest pain due to transient coronary artery spasm.
- Understanding the coronary arteriographic findings and clinical course is crucial for effective management.
Purpose:
- To review the clinical course and coronary arteriographic findings in patients with Prinzmetal's variant angina pectoris.
- To evaluate the treatment outcomes and prognosis in this patient cohort.
Summary:
- Five patients with Prinzmetal's variant angina pectoris presented with diverse coronary arteriographic findings, including coronary artery disease and spasm.
- Both medical management and surgical revascularization led to significant symptomatic improvement, with one patient experiencing spontaneous angina resolution.
- Normal left ventriculograms and varied left end-diastolic pressures were observed across the patient group.
Impact:
- This study suggests that Prinzmetal's variant angina pectoris can present with varied arteriographic findings.
- The prognosis for Prinzmetal's variant angina pectoris may be more favorable than previously thought.
- Findings support individualized treatment approaches based on coronary anatomy and patient presentation.
Abstract:
The clinical course and coronary arteriographic findings in 5 patients with Prinzmetal's variant angina pectoris are reviewed. In 4 patients who had ST-elevations inferiorly, 1 had minimal, 1 only slight, and 1 medium coronary artery disease; 1 had coronary spasm. 1 patient with ST-elevation anteriorly had severe stenosis of the anterior descending coronary artery. All 5 patients had normal left ventriculograms, 3 also had normal left enddiastolic pressure, and 2 slight elevation. Medical treatment was carried out in 2 patients and surgical revascularization in 2. Both treatments were accompanied by marked symptomatic improvement. Spontaneous loss of angina occurred in 1 patient. Prinzmetal's variant angina pectoris may be accompanied by a variety of coronary arteriographic findings and the prognosis appears to be more favorable than previously reported.
