Summary
A patient experienced chest pain due to coronary vasospasm despite a stented left anterior descending artery. In-stent restenosis developed 6 months after left internal mammary artery implantation, indicating ongoing challenges with vasospastic angina management.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Coronary vasospasm can lead to severe cardiac events like myocardial infarction and ventricular fibrillation.
- Medical management of coronary vasospasm is often challenging, necessitating interventional approaches.
- Left internal mammary artery (LIMA) grafts are used in coronary artery bypass grafting.
Observation:
- A 55-year-old male presented with chest pain 6 months post-LIMA implantation.
- The patient had a history of medically uncontrolled coronary vasospasm.
- A stent was previously placed in the proximal left anterior descending (LAD) artery due to ergonovine-proven spasm.
Findings:
- The patient developed in-stent restenosis in the LAD artery stent.
- Recurrent vasospastic angina episodes persisted despite prior interventions.
- Complications included ventricular fibrillation and myocardial infarction attributed to coronary spasm.
Implications:
- In-stent restenosis is a significant complication following stenting for coronary vasospasm.
- Management strategies for coronary vasospasm require careful consideration of restenosis risk.
- Further investigation into optimal treatment pathways for refractory coronary vasospasm is warranted.

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...
01:26Angina IV: Management
IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...
01:27Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
01:26Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
