TL;DR: A full understanding of the natural history of pulmonary embolism is elusive at the present time because many basic facts are either uncertain or unknown as mentioned in this paper, which makes it very difficult to classify the primary cause of death in patients in whom pulmonary embolness occurs as a fatal complication of other diseases.

TL;DR: A very schematic summary of possible factors that affect coronary vascular resistance is illustrated and chemical factors known to be released by the heart may play a role by modulating the coronary sensitivity to adenosine and other factors.

TL;DR: Hemodynamic correlations, made for the first time in patients, suggest that acute ventricular dilatation, possibly in combination with hypoxemia, is a causative factor of the electrocardiographic changes in acute massive or submassive pulmonary embolism.

TL;DR: Differences in survival were most striking in patients with isolated anterior descending, double and triple vessel involvement, and in a subgroup of 741 consecutive patients operated upon with pure graft techniques, survival seemed to be improved when compared to another group of similar, but nonoperated patients.

TL;DR: In congestive heart failure, patients appear to have alimited ability to dilate their resistance vessels in skeletal muscle in response to a metabolic stimulus, which can be considered a positive compensatory mechanism in that it helps to maintain systemic arterial pressure during exercise when the cardiac output fails to increase normally.

TL;DR: This article will attempt to demonstrate receptors in the atria and ventricles and neural pathways which lead, when the stimulus is applied to the appropriate receptor, to changes in heart rate, blood pressure, and urine flow.

TL;DR: In the majority of patients with pulmonary embolism, the primary objective of therapy is to prevent recurrence, and therefore, a course of anticoagulants is the only therapy indicated, and outlook for recovery is excellent.

TL;DR: The results of an international survey prepared for the Scientific Council of Cardiac Rehabilitation of the International Society of Cardiology will be reviewed to emphasize the multiple complexities inherent to the field.

TL;DR: A major advance was the recognition that these forms of circulatory collapse involved a substantial reduction in circulating blood volume, either as an early inciting factor, or secondarily as a consequence of a slow but continuous extravascular loss of fluid.

TL;DR: To what extent palliative and corrective surgery has influenced subsequent growth is examined to reduce the likelihood of growth retardation in infants and children with congenital heart disease.

TL;DR: The controversy stimulated by this procedure has resulted in continued and considerable accrual of information regarding massive pulmonary embolism, which remains heated, both in the literature and from the speaker's podium.

TL;DR: Definitive, if not curative surgery is available for the eight most common congenital cardiac defects-ductus arteriosus, ASD, coarctation, pulmonary valve stenosis, aortic valve stenotic, tetralogy of Fallot, and transposition.

TL;DR: This communication shall deal with a detailed comparison of pulmonary angiography and lung scan in the assessment of thrombolytic therapy in patients with pulmonary embolism.

TL;DR: Echocardiography is a useful new technique that allows for the diagnosis and assessment of the severity of various forms of valvular heart disease and the usefulness of ultrasound will be further enhanced.

TL;DR: The late and persistent postoperative ECG findings in congenital cardiac lesions are reviewed, with particular reference to: resolution of abnormal preoperative findings, the development of new abnormal postoperative patterns, and chronic rhythm disturbances.

TL;DR: It is apparent that close liaisons must be formed and maintained between physicians who care primarily for children with heart disease and adult cardiologists in order to provide adequate longitudinal studies to evaluate current therapy for all patients with congenital heart disease.

TL;DR: The purpose of this review is to provide physicians with information regarding potential late complications and the management of the postoperative patient after cardiac surgery for congenital heart disease.

TL;DR: The postero-anterior and lateral film of the chest with the barium-filled esophagus is one of the simplest, most important noninvasive technique to follow patients and emphasizes the importance of cardiovascular radiology in the postoperative management of these patients.
