Large thrombo-emboli thatarise from a cardiac or other proximal source and lodge at theaortic bifurcation‚ referred to as saddle emboli‚ can lead toprofound acute bilateral lower extremity ischemia (blue toe syndrome).(Wingo et al‚ 1986) In contrast‚ occurs when atheroscleroticdebris breaks free from an aortic or iliac plaque andembolizes

Chest pain or pressure that patients feel is commonly called angina. This usually occurs as a symptom of a problem with the heart and its blood supply. There are two types of angina called stable and unstable. Stable angina is where a person is feeling pain‚ chest pressure‚ or radiant pain in left arm and back with exertion. The more serious type is unstable angina‚ which means having those symptoms even at rest. There is a system of arteries that supply oxygen rich blood to the myocardium‚ or heart

the “Tromso” study‚ it indicates that among 29‚967 participants (55.7% were male)‚ 1662 participants with AF were diagnosed with thromboembolism (VTE) and about 50 (9.3%) subjects who experienced subsequent atrial fibrillation after a VTE event. Thrombus is most likely to manifest as Venous Thrombosis‚ it most commonly affects leg vein‚ such as the femoral vein. Haemorrhagic and ischemic may occur in patients with AF either as the intitail presenting manifestion of AF or despite appropriate antithrombotic

Atrial fibrillation is the most common cardiac arrhythmia that is associated with a reduced quality of life and an increased number of adverse outcomes such as stroke‚ heart failure‚ increased number of hospitalizations and mortality. Prevalence in developed countries is currently 1.5-2% of the general population‚ with the incidence steadily rising. Hence‚ prevalence is estimated to at least double in the next 50 year as the population ages. It has become a big deal for the health care system in

Atherosclerosis: the clogging and narrowing of the arterial walls with deposits of fat‚ cholesterol and other compounds known as plaque Ischemia: inadequate blood flow due to constriction/blockage of an artery‚ resulting in oxygen supply < oxygen demand Thrombus: A blood clot formed within the vascular system of the body and impeding blood flow. Manifestations of CVD: • Angina Pectoris: possible areas of radiating pain: neck‚ jaw‚ upper abdomen‚ shoulders and arms • Myocardial Infarction: heart attack

TIAs are powerful forerunners of stroke. Approximately 10% of patients diagnosed as having a TIA have a stroke in the 90 days following the TIA diagnosis‚ with half of them having a stroke within 2 days of the TIA. TIAs are short-lived episodes of acute‚ focal‚ nonconvulsive neurologic dysfunction presumably caused by reversible ischemia to an area of the retina or brain. Onset of symptoms is sudden and often unprovoked‚ reaching maximum intensity almost immediately. Completed Stroke A completed

Low Molecular Weight Heparin Paper Low molecular weight heparin is typically used for patients who need to be treated for deep vein thrombosis. Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein usually in the legs. These clots are dangerous because they can break loose‚ travel through the bloodstream to the lungs‚ and block blood flow in the lungs (pulmonary embolism). There are many reasons why clots form in a patient. Mainly
