RT Journal Article SR Electronic T1 Management of vasospastic angina JF Heart JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 70 OP 77 DO 10.1136/heartjnl-2022-321268 VO 109 IS 1 A1 Beltrame, John F YR 2023 UL http://heart.bmj.com/content/109/1/70.abstract AB Vasospastic angina is a well-established cause of chest pain that is caused by coronary artery spasm. It can be clinically diagnosed during a spontaneous episode by documenting nitrate-responsive rest angina with associated transient ischaemic ECG changes but more often requires provocative coronary spasm testing with acetylcholine during coronary angiography. Vasospastic angina may result in recurrent episodes of angina (including nocturnal angina), which can progress on to major adverse cardiac events. Calcium channel blockers are first-line therapy for this condition, given their anti-anginal and cardioprotective benefits. Despite an established diagnostic and therapeutic management pathway for vasospastic angina, this diagnosis is often overlooked in patients presenting with chest pain. Thus, there is need for increased clinical awareness of vasospastic angina to improve outcomes in affected patients.
