Abstract:
Objective To summarize the clinical features,treatment and follow-up of patients with severe coronary artery spasm.Methods Twenty-one patients with confirmed coronary artery spasm were selected.The study reviewed the patients' general conditions including age,gender,complication,smoking and drug situations.The clinical features,electrocardiogram and coronary angiography data were analyzed.Their diagnosis,treatment and prognosis were evaluated.Results Male (86％,18/21) had higher incidence in severe coronary artery spasm.Smoking (62％,13/21) was a major risk factor.Coronary artery spasm often happened on the base of a fixed narrow (57％,12/21),and the clinical process was treacherous.Coronary angiography was very important for early diagnosis.Calcium antagonist was the core of the treatments and should be sustained at full dose.Interventional therapy was not efficacious.Although patients in acute phase had higher risk,long-term prognosis was good.Conclusions Coronary artery spasm is a common problem,but it is often overlooked.Timely diagnosis is the key to prevent fatal events.Calcium antagonist is the core of the coronary artery spasm drugs.The long-term prognosis of coronary artery spasm is good.
