Variations in certain slopes of the carotid pulse which exist among normal subjects, patients with aortic valvular disease, and those with hypertrophic subaortic stenosis were examined. Records from 256 subjects were quantified with computer technics. The externally recorded volume pulses were related to simultaneously recorded brachial artery pressures (cuff); thus the slopes are expressed in ...

here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- monthhistory of dysphagia to liquids and solid foods with accompanying weight loss. on endoscopy, there was distalesophageal stenosis. multiple biopsies were obtained. histologic examination of the samples revealed normaltissue. the stenosis was treated by dilatation and abdomino pelvic comput...

This study was performed to determine if a coronary artery stenosis would result in more-severe perfusion abnormalities in hypertrophied compared with normal canine hearts during exercise. Studies were performed in eight normal control dogs and in seven adult dogs in which a 67% increase in left ventricular mass wa produced by banding the ascending aorta at 9 weeks of age. Myocardial blood flow...

a 51-year-old man was admitted to the emergency department with palpitation and atypical chest pain. he had a history of percutaneous mitral valve commissurotomy 20 years previously. he did not use any drugs. physical examination was unremarkable except for a loud s1 on auscultation. the surface electrocardiogram (ecg) showed atrial fibrillation rhythmwith rapid ventricular response and right b...

introduction takotsubo cardiomyopathy (tcmp) is a rare acute cardiomyopathy characterized by acute chest pain syndrome, similar to myocardial infarction, except that no significant stenosis is observed on coronary angiography in patients with this condition; these findings aid the diagnosis of tcmp. case presentation we discuss an unusual case of tcmp in a 45-year-old woman with complete heart ...

background: diagnosis of coronary artery disease (cad) in patients with left bundle branch block (lbbb) is considered as a challenge in cardiology due to the low accuracy of noninvasive methods such as basal and stress electrocardiography (ecg). this diagnostic challenge can be reduced but not eliminated using dipyridamole as a stress method instead of exercise. the aim of this study was to ass...

Many problems and complications associated with heart valves are related to the dynamic behavior of the valve and the resultant unsteady flow patterns. An accurate depiction of the spatial and temporal velocity and rms distributions imparts better understanding of flow related valve complications, and may be used as a guideline in valve design. While the generalized correlation between increase...

Simultaneous recordings have been made of electrocardiogram, phonocardiogram, carotid pulse tracing, left ventricular pressure, and aortic pressure in 27 children with aortic valve stenosis and 3 children with membranous subaortic stenosis. Peak systolic pressure difference ranged from 10 to 110 mmHg (1.3 to 14.6 kPa). None of the patients had congestive heart failure and cardiac output was in ...

Differences between prostaglandins I(2) and E(2) in their renal synthesis and pathophysiological roles were investigated in unilateral renovascular hypertension of different severities in 18 patients: 6 with mild stenosis (<75% of the diameter) of the renal artery, 7 with moderate stenosis (75% to 90%), and 5 with severe stenosis (>90%). Before and after aspirin administration (10 mg/kg), renal...
