Core Tip

Core Tip: The spasm provocation test (SPT) is a well-established tool for diagnosing coronary spasms. However, it is associated with several complications that can make the test a stressful experience. We investigated whether coronary spasms detected in the SPT can be estimated using intracoronary artery pressure measured with a pressure wire. We found that coronary spasms induced by low acetylcholine doses were associated with decreased intracoronary pressure at baseline. Coronary spasms induced by moderate-to-high acetylcholine doses showed decreased intracoronary pressure from baseline to low acetylcholine doses. These indices of intracoronary pressure may be used to predict coronary spasms.
