Usefulness of implantable cardioverter-defibrillators in refractory variant angina pectoris complicated by ventricular fibrillation in patients with angiographically normal coronary arteries

Increase in Internal Defibrillation Threshold During Acute Myocardial Infarction

“…In contrast to the several reports of successful ICD treatment of VF complicating acute ischemia (5,6), the present case suggests that, while a first ICD shock delivered for VF at an energy 10 J below maximum may be successful under stable testing conditions, it may not be strong enough during acute ischemia. It further suggests that, in ICD recipients suffering from coronary artery disease, special measures may be needed, such as the implant of a high energy device, the insertion of an additional lead, or special programmable functions for high DFT.…”

Cardiac arrest related to coronary spasm in patients with variant angina: a three‐case study

“…In our opinion, it is necessary in patients with variant angina after cardiac arrest who remain symptomatic, despite the treatment with maximally tolerated doses of calcium antagonists. It is in agreement with the opinion of Meisel et al [24].…”

Comparable Prognostic Value of Vasodilator Response to Acetylcholine in Brachial and Coronary Arteries for Predicting Long-Term Cardiovascular Events in Suspected Coronary Artery Disease

“…Even if the reported prognosis of vasospastic angina pectoris is plausible, sudden cardiac death can occur in patients with very active vasospasm. 24,25 In this respect, newly developed active vasospastic angina can be considered a CE classified as UA.…”
