Can you explain cardiac dysfunction in a patient with deep vein thrombosis?

Hello,

Welcome to icliniq.com.

DVT or deep vein thrombosis is a condition where blood clot accumulates in lower limb veins due to prolonged bedridden state, reduced physical activity, after a major surgery or fracture of bones. These blood clots can often dislodge and go through the right heart to block the pulmonary artery. This condition is known as pulmonary embolism and can cause right ventricular cardiac dysfunction. Pulmonary embolism is a critical medical condition and needs to be treated promptly with anticoagulant and diuretics. I see you are on a diuretics and you are overweight. Please inform about your findings of lower limb venous Doppler and also do some tests I am suggesting promptly and inform. Do Blood for complete hemogram, urea, creatinine, D-dimer, NT-proBNP (N-terminal prohormone of brain natriuretic peptide), Coagulation profile, Echocardiography with color Doppler, Report of lower limb venous Doppler, and Chest X-ray PA (posteroanterior) view.
