Acute pulmonary embolism: epidemiologic and tomodensitometric study

Area of Science:

• Cardiology
• Radiology
• Pulmonology

Background:

• Acute pulmonary embolism (PE) is a significant cause of morbidity and mortality.
• Prompt and accurate diagnosis of PE is critical for effective treatment.
• Cardio-thoracic specialized hospitals may have a different patient demographic for PE.

Purpose of the Study:

• To determine the prevalence of acute pulmonary embolism (PE) in a cardio-thoracic hospital.
• To evaluate the diagnostic accuracy of multidetector CT (MDCT) for PE.
• To calculate the sensitivity and specificity of MDCT in diagnosing PE.

Main Methods:

• Prospective study including 200 patients with suspected acute pulmonary embolism (PE).
• All patients underwent multidetector CT pulmonary angiography (MDCTPA) using a 16-slice scanner.
• Prevalence, sensitivity, and specificity of MDCTPA for PE diagnosis were calculated.

Main Results:

• The prevalence of acute pulmonary embolism (PE) was found to be 37.5%.
• Multidetector CT (MDCT) provided an alternative diagnosis in 40% of patients.
• MDCT demonstrated a sensitivity of 89.6% and a specificity of 100% for PE diagnosis.

Conclusions:

• The prevalence of acute pulmonary embolism (PE) is higher in specialized cardio-thoracic centers compared to general hospitals.
• Multidetector CT (MDCT) exhibits high sensitivity and specificity for diagnosing pulmonary embolism (PE).
• MDCT is confirmed as the gold standard for diagnosing pulmonary embolism (PE).
