Why the study?
Do clinical features and outcomes of coronary artery spasm differ in patients with versus without thyrotoxicosis?
Do clinical features and outcomes of coronary artery spasm differ in patients with versus without thyrotoxicosis?
Patients with coronary artery spasm and thyrotoxicosis have more severe clinical and angiographic presentations but similar clinical outcomes compared to those without thyrotoxicosis.
Answers are grounded in this paper and cite their sources.
Similar outcomes despite severe CAS presentations with thyrotoxicosis; hypothesis-generating for thyrotoxicosis effects but should not change practice.
Clinical and angiographic presentations of CAS with thyrotoxicosis were more severe than CAS without thyrotoxicosis, but clinical outcomes were similar in both groups. Optimal vasodilator therapy is essential for the management of CAS with thyrotoxicosis. Thyroid function test should be mandatory for all patients with CAS.
