TL;DR: There is a residual effect for glucose intolerance after all the standard risk factors and fibrinogen have been taken into account, which suggests a thrombogenic explanation for the unique diabetic effect.

TL;DR: It is suggested that CAD among persons who are predicted to be at low risk by standard risk factors may have a substantial genetic component and that the risk associated with parental history may not be reduced by modification of these factors.

TL;DR: The results of this study demonstrate that mass, volume, and functional measurements are reproducible in morphologically abnormal ventricles.

TL;DR: Large, protrusive plaques in the aortic arch and descending aorta, which have mobile projections that move freely with the blood flow are shown; these lesions could be responsible for embolic syndromes, especially after catheter manipulation in theAorta.

TL;DR: A new angiographic score that assesses the extent of coronary disease is simple to perform and correlates better with age and lipoprotein risk factors than conventional scores do.

TL;DR: Of the six common methods evaluated, the aortic annular leading edge method measures stroke volume with the best accuracy and is most suitable for clinical application.

TL;DR: A general introduction to the basics of the mathematics, applications to cardiology, and a brief review of the new tools needed to use the concepts of nonlinear mathematics are given.

TL;DR: It is suggested that idiopathic VF represents an underestimated cause of sudden cardiac death in ostensibly healthy patients and an international registry of patients with documented VF is warranted.

TL;DR: Intravascular imaging with high-frequency ultrasound is an accurate method for measuring microanatomic arterial dimensions and the extent of atheromatous involvement of the arterial wall and could represent an important adjunct to traditional angiographic techniques for assessing the severity of atherosclerosis.

TL;DR: The plasma ir-ET level is increased in the acute phase of AMI, and a pathophysiologic state characterized by cardiac dysfunction, an activated coagulation system, and platelet hyperactivity may be associated with this increase.

TL;DR: It is indicated that permanent, apically-initiated VVI pacing ultimately predisposes to adverse cellular changes associated with hemodynamic and electrophysiologic deterioration in the intact, developing immature canine heart.

TL;DR: The results show that the magnitude of time required to evaluate, transport, and initiate thrombolytic therapy will preclude initiation of treatment to most patients within the first hour of symptoms.

TL;DR: Although PTCA in chronic dialysis patients is technically feasible and provides relief of angina, aggressive restenosis limits the long-term benefit andCoronary bypass surgery may be the preferred therapy for this unique patient group.

TL;DR: While the crude long-term survival rate for patients with AF was poorer than that of patients without AF for the combined as well as for individual study periods, similar to the in-hospital findings the independent effect of AF on long- term prognosis was not upheld after use of a multivariate analysis.

TL;DR: These findings permit the following conclusions on cardiac changes induced by high-performance sports and high levels of training to be drawn.

TL;DR: A normal exercise echocardiogram in a patient with good exercise capacity was predictive of an excellent prognosis, even in those who had abnormal exercise ECGs, and myocardial infarction and death were rare events,Even in patients with decreased exercise capacity.

TL;DR: Some of the risk factors associated with coronary heart disease are examined, notably, advancing age, hypertension, left ventricular hypertrophy, smoking, elevated serum cholesterol, and reduced high-density lipoprotein, all of which have been investigated by the Framingham Heart Study.

TL;DR: In cases in which no pathologic condition was identified, transesophageal echocardiography was useful in ruling out intracardiac shunt, in assessing left ventricular function, and in excluding significant valvular pathologic conditions.

TL;DR: Findings suggest that a history of prior angina is not necessarily associated with an unfavorable short-term prognosis after reperfusion therapy, and may be related to the beneficial effects of collateral vessels, myocardial preconditioning, or differences in the native fibrinolytic system.

TL;DR: The noncardiac mode of death in a large percentage of the patients suggests that the bypass operation prolonged life to a degree sufficient for another condition to develop, and therapy after the operation must be directed toward prevention of progression of the atherosclerosis in the "new" coronary "arteries."

TL;DR: Pericardial effusion may be a frequent manifestation in myxedema, an advanced severe stage, but a rare association of hypothyroidism, an early mild stage, because of the timeliness with which the latter condition is nowadays detected.

TL;DR: Inter intravenous dipyridamole thallium scintigraphy is a useful noninvasive test for risk stratification of patients before peripheral vascular surgery and provides prognostic information as to the risk of a cardiac event in the 2-year period after the test.

TL;DR: The prevalence of heart failure in Northwest London is 0.4%, a lower figure than that quoted for the United States, and the prognosis for patients admitted to the hospital is poor.

TL;DR: Progress of aortic stenosis as assessed by Doppler echocardiography was examined, and patients reported an increase in symptoms from the first to third examination, and their rate of progression was significantly different from that of the rest of the population.

TL;DR: Aerobic exercise training favorably alters plasma lipoprotein profiles and a minimum training intensity equal to 75% maximal heart rate is required to the increase HDL cholesterol level.

TL;DR: It is concluded that visual estimates of lesion severity are consistently and significantly higher than quantitative measurements, and restenosis rates, using currently applied definitions, differ considerably depending on the method of analyzing lesions severity.

TL;DR: The last decade has witnessed an enormous increase in the use and success of percutaneous transluminal coronary angioplasty and of how it relates to the pathophysiology of restenosis, and it is likely that the problem ofrestenosis will be improved, either through existing technology or by methods yet to be discovered.

TL;DR: The results suggest that unsuspected coronary artery disease is common in this particular group of patients with diabetes mellitus, particularly in patients with concomitant hypertension and cigarette smoking.

TL;DR: Radionuclide angiography in the diagnosis of congenital intrapericardial aneurysm of the left atria1 appendage and cross-sectional echocardiography.
