Coronary embolism in valvular heart disease
The Quarterly Journal of Medicine
|January 1, 1982
Summary
Coronary embolism, often overlooked, is a significant cause of acute myocardial infarction, particularly in patients with normal coronary arteries. This condition can lead to severe cardiac complications and death.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Coronary embolism is increasingly recognized as an underdiagnosed cause of acute myocardial infarction (AMI).
- Evidence suggests a potential link between coronary embolism and AMI in patients with angiographically normal coronary arteries.
Observation:
- A study of 26 patients revealed coronary embolism as the primary cause of death in 6 (23%) and diagnosed clinically in 20 (77%).
- Left coronary system occlusion occurred in 65% of cases, with 30% experiencing transient electrocardiographic changes.
- Atypical or absent history of AMI was noted in 29% of patients, and 25% had other systemic emboli.
Findings:
- Aortic valve lesions were present in 70% of patients, and combined mitral and aortic valve disease in 55%.
- Traditional coronary risk factors were infrequently observed.
- Sequelae included dyspnea (35%), ventricular aneurysm (25%), and cardiac failure (12%).
Implications:
- Coronary embolism should be considered in the differential diagnosis of AMI, especially with normal coronary arteries.
- Identifying aortic valve disease is crucial as it is a common predisposing factor.
- Further research is needed to improve diagnostic strategies and patient outcomes for coronary embolism.

01:26Coronary Artery Disease II: Pathophysiology
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
01:30Coronary Artery Disease III: Clinical Manifestations
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
01:27Pulmonary Embolism III: Nursing Management
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
