Refractory vasospasm with a malignant course

Area of Science:

• Cardiology
• Vascular Medicine
• Transplant Surgery

Background:

• Recurrent vasospastic angina can lead to severe cardiac events, including myocardial infarction and sudden cardiac death, often refractory to standard medical therapy.
• Acute aortic occlusion is a critical vascular emergency, and its association with vasospasm is uncommon.
• Cardiac transplantation is a life-saving option for end-stage heart failure due to conditions like severe coronary vasospasm.

Observation:

• A patient experienced recurrent episodes of coronary vasospasm, manifesting as unstable angina and myocardial infarction, despite treatment with nitrates and calcium-channel blockers.
• The patient subsequently underwent a cardiac transplant due to the severity of his coronary vasospastic disease.
• Post-transplant, the patient developed acute aortic occlusion, accompanied by renal and mesenteric artery spasm.

Findings:

• The co-occurrence of severe coronary vasospasm requiring cardiac transplant and acute aortic occlusion with visceral artery spasm suggests a possible underlying generalized vasospastic diathesis.
• Smoking was identified as a significant risk factor, temporally associated with both the vasospastic angina and the acute aortic occlusion events.

Implications:

• This case underscores the importance of considering a systemic vasospastic predisposition in patients presenting with seemingly unrelated, severe vascular events.
• Identifying and managing risk factors like smoking may be crucial in preventing catastrophic outcomes in individuals with vasospastic disorders.
• Further research into the mechanisms of generalized vasospasm could lead to novel therapeutic strategies for these rare conditions.
