Significant Characteristics of Variant Angina Patients with Associated Syncope.

Abstract

To determine whether syncope predisposes to sudden cardiac death, variant angina patients with syncope during cardiac attacks were compared with those without syncope. There were 240 consecutive patients (193 males and 47 females) diagnosed with variant angina pectoris. Thirty patients had a history of syncope during cardiac attacks while the remaining 210 had none. The incidence of cardiac events in the former group was 10.0% (3 of 30) and 10.5% in the latter. There were 3 cases of sudden cardiac death, all in the latter group. Significant clinical variables in the syncope patients included inferior ST-segment elevation and serious arrhythmias. We conclude that there is no relationship between syncope during variant angina and sudden cardiac death.

ST Elevations and Ventricular Tachycardia Secondary to Coronary Vasospasm upon Extubation

“…Although the most common cause of ST elevations (STE) in the perioperative setting is acute coronary syndrome (ACS), alternative diagnoses should be considered to ensure the patient does not undergo unnecessary and invasive investigations [4]. ST-changes in coronary vasospasm usually last less than 15 minutes, with the electrocardiogram (ECG) spontaneously returning to baseline [5].…”

Prinzmetal angina: An unrecognized cause of recurrent ST elevation myocardial infarction

“…Patients with VA show ST segment elevation and reciprocal depression on ECG during attacks of chest pain. Ambulatory ECG monitoring in patients with VA showed circadian variation with most of the ischemic episodes occurring between midnight to early morning hours with peak frequency around 05.00 h [6]. Another important feature of VA is the frequency of asymptomatic ischemic episodes being much higher than symptomatic episodes.…”

“…Another important feature of VA is the frequency of asymptomatic ischemic episodes being much higher than symptomatic episodes. One study revealed that 82% (872 out of 1062) of episodes were asymptomatic [6]. Severe arrhythmias, including ventricular tachycardia, highdegree atrioventricular block, and bradyarrythmias resulting in syncopal episodes may be occasionally seen during an attack of VA.…”

“…These syncopes have been associated with severe cardiac arrhythmias such as ventricular tachycardia or fibrillation, bradyarrhythmias, as well as atrioventricular block [17].…”
