The Correlation between Pulmonary Embolism and Heart Disease
Embolism is a solid, liquid, or gaseous mass that is detached intravascular, and carried by the blood to a site distant from its point of origin. Inevitably, emboli lodge in vessels too small to allow further movement, leading to partial or complete occlusion of the vascular(1). So, most usual forms of emboli (90%) are thromboemboli i.e. arising from thrombi or their parts detached from the wall of the vessels(2). As well as rare forms of emboli include fat droplets, atherosclerotic debris (cholesterol emboli), bubbles of air or nitrogen, tumor fragments, bits of bone marrow or foreign bodies such as bullets(1)

Background: Heart diseases increase the risk of arterial embolism; whether they increase the risk of pulmonary embolism. Methods: I take two studies; the first study was taken from Denmark using patients diagnosed with pulmonary embolism between 1980 and 2007. which contains records of acute care hospital discharges since January 1, 1977. And the second study was taken from Veneto region in Italian, they involved patients with the first inpatient hospital discharge diagnosis of pulmonary embolism recorded from January 1, 2000 to December 31, 2006. Results: according to the first study, there was 109,752 cases, of whom 45282 patients had pulmonary embolism alone, 4680 had pulmonary embolism and deep venous thrombosis, and 59790 had deep venous thrombosis alone. However, for the second study, there was 13,053 patients discharged from hospitals in the Veneto region with a diagnosis of PE, they excluded 1817 patients younger than 60 years, Of the remaining 11,236 patients, 9079 had PE diagnosis alone. Conclusion: both studies are proving that heart diseases increase the risk of pulmonary embolism.
