Vasospastic angina, also known as Prinzmetal's angina, is thought to occur due to vascular hyper-reactivity to various stimuli. Response to medical therapy is usually good; however, 1 out of 5 patients has resistant symptoms. Rarely, potentially lethal arrhythmias can occur due to vasospasm, and those patients are reported to have a poorer prognosis. Presently described is a case of resistant vasospastic angina with persistent symptoms under calcium channel blocker and nitrate treatment. The patient presented with hemodynamically unstable rapid-rate ventricular tachycardia, which was quite resistant to recurrent cardioversion. She was treated with stent implantation for definite vasospastic segments of the coronaries, in combination with medical therapy. An implantable cardioverter defibrillator was also implanted for secondary prevention of ventricular arrhythmia, as vasospasm was considered to be a diffuse disease without a certain definitive treatment.

Angina pectoris (AP), a clinical syndrome characterized by paroxysmal chest pain, is caused by insufficient blood supply to the coronary arteries and sudden temporary myocardial ischemia and hypoxia. Long-term AP typically induces other cardiovascular events, including myocardial infarction and heart failure, posing a serious threat to patient safety. However, AP's complex pathological mechanisms and developmental processes introduce significant challenges in the rapid diagnosis and accurate treatment of its different subtypes, including stable angina pectoris (SAP), unstable angina pectoris (UAP), and variant angina pectoris (VAP).

This case report describes a 15-year-old boy who presented with vasospastic angina (VSA). His symptoms included chest and back pain, nausea, and respiratory distress. After undergoing diagnostic tests, including coronary angiography and an acetylcholine provocation test, the patient was diagnosed with VSA.

Background: A considerable number of symptomatic patients leave the cardiac catheterization lab without a definitive diagnosis for their symptoms because no epicardial stenoses are found. The significance of disorders of coronary microvasculature and vasomotion as the cause of symptoms and signs of ischemia has only recently been appreciated. Today we have a wide spectrum of invasive coronary physiology tools but little is known about when and how these tools are used in clinical practice.
