Clinical characteristics and long-term prognosis of patients with variant angina. A comparative study between western and Japanese populations

Dual Induction Tests Save Patients Surviving Out-of-Hospital Cardiac Arrest

“…Coronary spasm occurs in various cardiac conditions, such as acute coronary syndrome, ventricular tachycardia and fibrillation, sudden cardiac death, syncope, silent ischemia and other miscellaneous disorders. [2][3][4][5][6] Japanese patients have had spasm provoked at a rate 3-fold higher than in Caucasian patients 7 and in our data also, coronary spasm was induced in approximately 50% of patients with ischemic heart disease. 8 In Asian patients, coronary spasm is an important key to diagnosing possible ischemic heart disease.…”

Gender Differences in the Clinical Characteristics and Outcomes of Patients With Vasospastic Angina

“…Previous studies demonstrated a higher prevalence of male gender in VSA patients [16][17][18] and only a few studies examined …”

“…15 It has been also demonstrated that the prevalence of VSA is higher in men than in women. [16][17][18] However, it remains to be elucidated whether there are gender differences in the clinical characteristics and long-term prognosis of VSA. Thus, in the present study, we addressed this important issue in the nationwide multicenter study conducted by the Japanese Coronary Spasm Association.…”

Pathophysiology of Ischemic Heart Disease with Special Reference to the Degree of Organic Stenosis of the Coronary Artery

“…We reviewed the clinical characteristics and the long term prognosis of 158 consecutive Japanese patients with variant angina and compared the data with those in major western studies (1). The Japanese patients were characterized by the low prevalence of significant coronary stenosis and previous myocardial infarction, and as expected, the overall prognosis of variant angina was significantly better in the Japanese patients than in the non-Japanese populations.…”
