Forty consecutive patients with creatine kinase-MB confirmed myocardial infarction due to circumflex artery occlusion (Group 1) were prospectively evaluated and compared with 107 patients with infarction due to right coronary artery occlusion (Group 2) and 94 with left anterior descending artery occlusion (Group 3). All 241 patients underwent exercise thallium-201 scintigraphy, radionuclide ven...

ide, Q , the P f this 2) sele A 67-year-old diabetic man with a pacemaker for symptomatic bradycardia underwent cardiac catheterization for unstable angina, 19 years after coronary artery bypass graft surgery. There were bilateral pedicled internal mammary grafts—from the left internal mammary artery (LIMA) to the left anterior descending coronary artery (LAD), and from the right internal mamma...

We report here on a 43-year-old female patient presenting with non-ST elevation myocardial infarction, severe mitral regurgitation, and mild mitral stenosis secondary to encroachment of the related structures by a primary cardiac angiosarcoma. A coronary angiography revealed significant stenosis in the left main and left circumflex arteries and at exploration, the tumour was arising from poster...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

BACKGROUND The use of the vasodilating agent adenosine as stressor in conjunction with myocardial contrast echocardiography has not been extensively evaluated in hypertensive patients. Our aim was to evaluate the diagnostic value of adenosine myocardial contrast echocardiography (MCE) in comparison to single-photon emission computed tomography (SPECT), with reference to angiographic findings, i...

ECG diagnosis of a posterior wall myocardial infarction is difficult to diagnose through the standard 12 lead ECG, especially in the acute stage. The posterior wall MI may occur as an isolated event or often associated with an inferior wall myocardial infarction Posterior leads V7, V8 and V9 are usually ignored but it is suggested that these leads can provide ECG information that is useful for ...

The medial circumflex femoral artery usually arises from the deep femoral artery. It supplies the supplies adductors and hamstring group as well as sciatic nerve and femoral head and neck through anastomosis. In current study includes 342 dissected hemipelvis to clarify the origin of medial circumflex femoral artery. The medial circumflex femoral artery arose from the common and deep femoral ar...

BACKGROUND Previous work showed a twofold increase in stiffness of nonischemic myocardium at the base during ischemia of the left anterior wall. Whether the diastolic response of nonischemic myocardium to remote ischemia depends on the localization of the ischemic or the nonischemic area is unknown. METHODS In dogs with open chests, regional function in ischemic and nonischemic myocardium was...

ic with chest discomfort suggesting stable angina pectoris. He had hypertension and smoking as risk factors for coronary artery disease. Physical examination was entirely normal. Resting ECG revealed negative T waves on anterolateral leads. Coronary angiography demonstrated critical coronary lesions in the proximal part of the left anterior descending artery and the mid-portion of the diagonal ...
