Quantification of coronary artery calcium using ultrafast computed tomography.
TLDR
Ultrafast computed tomography was used to detect and quantify coronary artery calcium levels in 584 subjects and was more sensitive than fluoroscopy, detecting coronary calcium in 90% versus 52% of patients. Expand
ACC/AHA guidelines for the management of patients with unstable angina and non‐ST segment elevation myocardial infarction: Executive summary and recommendations
TLDR
The 2016-17 FACC curriculum vitae was presented at a special meeting of the American College of Physicians and Surgeons (ACS) in Washington, DC to discuss the design of the curriculum for the 2017-18 academic year. Expand
Cardiovascular effects of glucagon in man.
Ultrafast computed tomography-detected coronary calcium reflects the angiographic extent of coronary arterial atherosclerosis.
TLDR
The potential of ultrafast CT quantification of coronary calcium to reflect the extent of atherosclerosis measured by coronary angiography is demonstrated and the usefulness in finding a population of asymptomatic subjects in whom aggressive risk factor modification would be cost-effective should be explored. Expand
Coronary artery bypass surgery in patients seventy years of age and older.
TLDR
Age alone should not be a contraindication for coronary artery bypass surgery, and surgical risk is acceptable in older patients, and improvement can be expected in the majority of patients. Expand
Accuracy of the clinical diagnosis of pulmonary embolism.
TLDR
Neither symptoms, physical findings, ECG, serum enzymes, nor chest roentgenography were able to distinguish patients with embolism, and the isotope lung scan could accurately detect defects in lung perfusion but was unable to differentiate causes. Expand
Localization of A-V conduction defects in man by recording of the His bundle electrogram.
TLDR
In patients with first degree heart block during sinus rhythm the A-H time was prolonged and the H-V time was either normal or prolonged, and in higher degrees of heart block, the block was localized either in the proximal or distal A-V junction. Expand
Myocardial dysfunction associated with valvular heart disease.
TLDR
The demonstration of postoperative myocardial contractile abnormalities in previously normal patients suggests an intraoperative cause, perhaps related to cardiopulmonary bypass, and postoperative dysfunction may exist preoperatively and remain unchanged. Expand
Pseudo complications of cardiac catheterization.
TLDR
The incidence of annual complications would have doubled and the mortality rate would have tripled if the procedures had been performed on schedule or up to 48 hours earlier in the patients of the pseudo complication group. Expand
