Patients with acute myocardial infarction and non-obstructive coronary arteries: safety and prognostic relevance of invasive coronary provocative tests

Key Result

A positive provocative test for spasm in patients with MINOCA is safe and identifies a high-risk subset of patients.

Structured PICO

Does a positive invasive coronary provocative test for spasm safely identify a high-risk subset in patients presenting with MINOCA and suspected coronary vasomotor abnormalities?

Population

Patients presenting with MINOCA (myocardial infarction with non-obstructive coronary arteries) and suspected coronary vasomotor abnormalities

Intervention

Invasive coronary provocative tests for spasm

Outcome

Safety and prognostic relevance (identification of a high-risk subset)

Invasive coronary provocative testing is safe and provides important prognostic value by identifying high-risk patients among those presenting with MINOCA.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

We demonstrate that in patients presenting with MINOCA and suspected coronary vasomotor abnormalities, a positive provocative test for spasm is safe and identifies a high-risk subset of patients.
