Abstract:
Seventy-one patients with variant angina (VA) admitted in the Cardiology Department from January 2003 to March 2011,were divided into non-stenosis group (stenosis ＜ 50％,n =43) and stenosis group (stenosis ≥50％,n =28) according to the degree of stenosis.The differences of the risk factors,clinical manifestations,electrocardiogram,echocardiogram and laboratory examinations between these two groups were compared.The average age of patients in stenosis group 58 ± 8 y was higher than that in non-stenosis group (52 ± 9 y,t =2.43,P =0.02).Other risk factors,including male gender,smoking,hypertension,diabetes mellitus and lipid disorder did not show any differences between the two groups.Percentage of patients with angina pectoris lasting less than 5 min was higher in stenosis group (x2 =5.98,P =0.02),while percentage of effort angina,seeking medical consultation ≤ 6 months of onset and hemodynamic disorders showed no difference.Laboratory examinations had no differences.It is difficult to determine whether the VA patient has fixed coronary stenosis by analyzing the risk factors,clinical manifestations and laboratory examinations; to determine the fixed coronary stenosis coronary angiography is necessary.
