Venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism, affected 117 per 100,000 individuals annually. Early diagnosis and treatment of VTE are crucial for reducing patient mortality and morbidity.
Area of Science:
- Cardiovascular Medicine
- Epidemiology
- Hematology
Background:
- Deep vein thrombosis (DVT) and pulmonary embolism (PE) are significant causes of morbidity and mortality.
- Understanding the incidence and risk factors of venous thromboembolism (VTE) is crucial for public health.
- Previous studies have highlighted the importance of early diagnosis and treatment for VTE.
Observation:
- A retrospective cohort study analyzed 2,218 patients diagnosed with DVT or PE between 1966 and 1990.
- The study observed an annual incidence rate of VTE at 117 per 100,000 population.
- Higher VTE incidence rates were noted in males compared to females (130 vs. 110 per 100,000, respectively), even after age adjustment.
Findings:
- The annual incidence of VTE was 117 per 100,000, with DVT at 48 per 100,000 and PE at 69 per 100,000.
- Males exhibited higher VTE rates than females (130 vs. 110 per 100,000) after age adjustment.
- Identified risk factors for VTE include altered blood flow, hypercoagulability (e.g., Factor V Leiden mutation), and vessel wall abnormalities.
Implications:
- Prompt diagnosis and effective treatment of DVT and PE can substantially decrease mortality and morbidity.
- Recognizing risk factors such as obesity, surgery, pregnancy, and genetic mutations aids in VTE prevention strategies.
- While 80% of DVTs resolve spontaneously, the potential for pulmonary embolism necessitates vigilant management.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
