Comparison of clinical and laboratory findings between patients with diffuse three‐vessel coronary Artery Spasm and other types of coronary Artery Spasm
Catheterization and cardiovascular diagnosis, 1996Co-Authors: Kwang Kon Koh, Tai Hoon Moon, Joon Ho Song, Gi Soo Park, Kee Hyong Lee, Sang Kyoon Cho, Sam Soo KimAbstract:Our purpose was to compare patients with diffuse three-vessel coronary Artery Spasm and other types of coronary Artery Spasm without significant organic stenosis, and to elucidate clinical characteristics and risk factors. Patients were divided into two groups: group I consisted of 26 patients showing other types of coronary Artery Spasm; group II consisted of 5 patients with diffuse three-vessel coronary Artery Spasm. The mean age of patients in groups I and II was 52 and 50 years, respectively. The incidence of variant angina was higher in men than in women. The incidence of smoking was high in each group, but not significantly different. Exercise tests showed no significant differences between groups. All mean values of laboratory data, including lipoprotein (a) and low-density lipoprotein cholesterol in the two groups, were within normal ranges. There was no significant difference between groups. The incidence of spontaneous spam was much higher in patients with diffuse three-vessel coronary Artery Spasm (P < 0.01). Electrocardiographic (ECG) findings before the Spasm were almost normal. All 5 patients with diffuse three-vessel coronary Artery Spasm demonstrated no important ST segment changes with episodes of angina during a coronary angiography on 12-lead ECG, compared to patients with other types of coronary Artery Spasm (P < 0.01). First, we conclude, diffuse three-vessel coronary Artery Spasm mostly occurs spontaneously. Second, we emphasize that diffuse three-vessel coronary Artery Spasm must be considered when 12-lead ECG shows no important ST segment changes with episodes of angina. Third, it is not easy to distinguish diffuse three-vessel coronary Artery Spasm from other types of coronary Artery Spasm on the basis of history, laboratory data, or electrocardiographic findings, including exercise tests.

Various 12-lead electrocardiographic findings of diffuse three-vessel coronary Artery Spasm.
American heart journal, 1992Co-Authors: Kwang Kon KohAbstract:Abstract Electrocardiographic signs of diffuse three-vessel coronary Artery Spasm may show various findings including no ST segment changes, according to whether or not a difference of an electrical gradient developes between the anterior and inferior regions because of global ischemia. This study suggests that diffuse three-vessel coronary Artery Spasm must be considered when the 12-lead electrocardiogram (ECG) shows no important ST segment changes with episodes of angina and diffuse coronary Artery Spasm during an ergonovine provocation test in patients with strongly suspected variant angina.

Secondary prevention of sudden cardiac death in coronary Artery Spasm: Is implantable cardioverter defibrillator always efficient?
International journal of cardiology, 2006Co-Authors: Konstantinos P. Letsas, Gerasimos Filippatos, Michalis Efremidis, Antonios Sideris, Fotios KardarasAbstract:Syncope and/or cardiac arrest in the setting of coronary Artery Spasm have been associated with atrioventricular block and asystole or ventricular tachyarrhythmias. Ventricular arrhythmias have been predominantly reported in cases of multivessel coronary Artery Spasm. The present report highlights the case of a young woman who suffered repeated episodes of multivessel coronary Artery Spasm in association with polymorphic ventricular tachycardia and cardiac arrest. The efficacy of implantable cardioverter defibrillator in secondary prevention of sudden cardiac death due to coronary Artery Spasm is discussed.

Sudden cardiac death from coronary Artery Spasm in a healthy subject.
Catheterization and cardiovascular diagnosis, 1994Co-Authors: Marc A. Tecce, Bennett D. Schalet, Steven A. Roberts, Abdulmassih S. Iskandrian, Stephen A. Mette, Bernard L. SegalAbstract:The true incidence of sudden cardiac death (SCD) from coronary Artery Spasm is unknown. The following case involves SCD in a previously asymptomatic young man with reasonable evidence to implicate coronary Artery Spasm as a potential cause for his clinical event. Ergonovine provocation may be warranted in patients who present with SCD and no discernable cause.

Flash pulmonary edema heralding renal Artery Spasm.
Cardiology, 2007Co-Authors: Mohammad Bagher Sharifkazemi, Mahmood Zamirian, Amir AslaniAbstract:Flash pulmonary edema is a condition characterized by sudden and recurrent episodes of dyspnea resulting from acute pulmonary venous congestion in the presence of normal or well-preserved left ventricular systolic function. This is usually associated with bilateral renal Artery stenosis or stenosis of a single surviving kidney. We describe a patient with clinical presentation of flash pulmonary edema due to renal Artery Spasm. To the best of our knowledge, this is the first reported case of flash pulmonary edema due to renal Artery Spasm.
