P6004Safety assessment and results of coronary spasm provocation testing in patients with MINOCA compared to patients with stable angina and unobstructed coronary arteries

Abstract: Background Approximately 10% of patients with acute myocardial infarction do not have a culprit lesion. Such patients have been labelled as MINOCA (myocardial infarction with non-obstructive coronary arteries) and several pathophysiological etiologies have been described as potential explanations. This includes spontaneous coronary dissection, tako-tsubo-syndrome and coronary spasm. The latter can be diagnosed during invasive provocative testing. The aim of this study was to assess the freque… Show more

“…67,68 Small studies demonstrate that during the acute phase there are no irreversible complications; bradyarrhythmias occur in 5-16% of cases, which is comparable to that seen in stable patients with non-obstructive coronary arteries (15%),and ventricular tachyarrhythmias are rare (<0.5%), but this is clearly not in the setting of STEMI. 48,69 There are important prognostic benefits to reaching a correct diagnosis and accurately identifying and treating patients with coronary vasospasm, therefore routine vasospasm provocation testing is strongly encouraged in patients with MINOCA. 48,70 Follow-up Investigations (Figure 4).…”
