The tobacco industry proposes to release a "new" cigarette with a burning charcoal tip, which heats the tobacco as air is drawn through it and into the lungs of the smoker. It is claimed to be safer because the tobacco does not burn. Using our established canine model of coronary artery stenosis
This study was undertaken to examine in vivo the effects of cigarette smoke on cyclic reductions in coronary flow due to platelet thrombus formation in the stenosed coronary arteries of anesthetized dogs. The circumflex coronary artery of 21 mongrel dogs was stenosed 60 - 80%, with blood flow
OBJECTIVE
Cigarette smoking is linked to thromboembolic events; however, a relationship between nicotine exposition and thrombosis has not been established. Thus, we intended to study the effect of acute and chronic nicotine application in an in vivo mouse model.
METHODS
In microvessels of the
The causal link between smoking, atherosclerosis and an increased risk for acute platelet mediated coronary events such as acute platelet thrombus formation, myocardial infarction, and sudden coronary death is not clear. Our studies suggest that there may be a transient increase in in vivo platelet
Lumbrokinases, a group of fibrinolytic enzymes extracted from earthworm, have been widely used to prevent and treat various cardiovascular diseases. They specifically target fibrin to effectively degrade thrombi without major side effects. Plant expression systems are becoming potential alternative
To identify tobacco recidivism among 86 heart transplant recipients who were smokers but demonstrated compliance with a smoking cessation program pre-transplant, we used a questionnaire and randomly tested urine for nicotine and its by-products. In 36 patients, we also evaluated circulating levels
Background: Thrombosis after liver transplantation is a leading cause of graft loss, morbidity, and mortality. Several known recipient- and surgery-related characteristics have been associated with increased risk of thrombosis after
OBJECTIVE
The true incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing laparoscopic radical prostatectomy is unknown. Our aim was to determine the incidence of symptomatic DVT and PE and the risk factors for these complications.

Thromboangiitis obliterans, a distinct clinical and pathologic entity characterized by segmental inflammatory and proliferative lesions of the tunica media of small arteries and veins, has been reported frequently in men who have a history of heavy cigarette smoking. We report a case of
Introduction: Portal venous thrombosis is a life-threatening cause of abdominal pain. In younger patients, heritable thrombophilias, pregnancy, tobacco use, and oral contraceptives are associated.
