The decision to administer thrombolytic therapy for limitation of acute myocardial infarction (AMI) size must occur when only the history, physical examination and 12-lead electrocardiogram of a patient are available. A method that could quickly assess the amount of jeopardized myocardium would greatly aid the physician. This study developed formulas from(More)
Imaging and color flow Doppler echocardiography are an integral part of any evaluation of a patient with the Marfan syndrome. The major cardiovascular manifestations of this condition are aortic dilation, which may involve the proximal and distal aorta, aortic regurgitation, aortic dissection, mitral valve prolapse, and mitral regurgitation. Patients who(More)
BACKGROUND Cigar smoking has become a quickly growing trend among teenagers, women, and young adults. The objective was to explore whether cigar smoking affects flow-mediated vasodilation in healthy, non-smoking young adults. METHODS This was a prospective randomized trial with open design. It was performed in a cardiology teaching program in a private(More)
Current coronary care electrocardiographic (ECG) monitoring techniques are aimed at detection of cardiac arrhythmias rather than myocardial ischemia. However, in patients with acute myocardial infarction (AMI) who undergo reperfusion therapy, monitoring ST-segment deviation could provide an early noninvasive indicator of coronary artery reocclusion. In this(More)
The aorta is a commonly unrecognized source of systemic embolization. Transesophageal echocardiography is a reliable method for visualization of the intima of the thoracic aorta and identification of aortic thrombi. Balloon embolectomy of the aorta can be used to remove thrombi and prevent further embolic events.
Stress echocardiography has become an accepted noninvasive method for the diagnosis of coronary artery disease. Stress echocardiography is more sensitive than exercise electrocardiography and as sensitive and specific as radionuclide perfusion studies for detecting coronary artery disease. Pharmacologic stress echocardiography using dobutamine also has(More)
Previously developed formulas for predicting the final QRS estimated sizes of acute myocardial infarcts from the initial ST segment deviation are tested. The population contains patients with either anterior or inferior infarcts from two hospitals in Copenhagen, Denmark. The formula for anterior location that considers only the number of ECG leads with ST(More)
