Key result

Intracoronary administration of ergonovine provoked coronary vasospasms in 29.0% of Japanese patients undergoing coronary angiography, with higher rates in those with ischemic heart disease.

Population

596 consecutive Japanese patients undergoing coronary angiography (mean age 64.2 +/- 10.3 years, 369 men).

Design

Cohort

Authors

Discussion

Overview

Incidence of intracoronary ER spasms higher than prior IV reports; leaves open optimal protocol and applicability outside Japanese cohorts.

Study Design

Type

Observational (n=596)

Structured PICO

Population

596 Japanese patients (mean age 64.2 years, 38.1% female) undergoing coronary angiography who were evaluated with a selective intracoronary ergonovine provocation test.

Exposure

Intracoronary administration of ergonovine (40 microg into the right coronary artery and 64 microg into the left coronary artery).

Outcome

Incidence of provoked coronary spasms (defined as a total or subtotal occlusion).surrogate

Intracoronary ergonovine provocation is a safe test that reveals a high incidence of coronary vasospasm in Japanese patients, particularly those with rest angina or significant atherosclerotic lesions.

Sueda et al. (2004) conducted an observational in Patients undergoing coronary angiography (n=596). Intracoronary administration of ergonovine was evaluated on Incidence of provoked coronary arterial spasms (defined as total or subtotal occlusion). Intracoronary administration of ergonovine provoked coronary vasospasms in 29.0% of Japanese patients undergoing coronary angiography, with higher rates in those with ischemic heart disease.
