Angina Severity and Symptom Improvement Are Associated With Diagnostic Acetylcholine Provocation Dose in Vasospastic Angina.

Background: A coronary function test (CFT) is the recommended diagnostic test to identify coronary vasomotor dysfunction as a cause of symptoms in patients with angina and nonobstructive coronary arteries (ANOCA). Acetylcholine is the commonly used pharmacological agent for spasm provocation. We aimed to investigate an association between severity of symptoms and provocative acetylcholine dose.

Myocardial infarction care in low and high socioeconomic environments: claims data analysis.

Background: To date, claims data have not been used to study outcome differences between low and high socioeconomic status (SES) patients surviving ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) in the Netherlands.

Aim: To evaluate STEMI and NSTEMI care among patients with low and high SES in the referral area of three Dutch percutaneous coronary intervention (PCI) centres, using claims data as a source.

Methods: STEMI and NSTEMI patients treated in 2015-2017 were included.
