Coronary Angiographic Findings of Nepalese Patients with Critical Coronary Artery Disease: Which Vessels and How Severe?

Background: Coronary heart disease is a rising cause of adult death in Nepal. Diagnostic and interventional facilities such as coronary angiography and angioplasty have also collaterally improved in Nepal over the last decade. This study explores the most common coronary vessels involved in the Nepalese population based on the coronary angiographic findings. Methods: This is a retrospective study of 852 Nepalese patients who underwent coronary angioplasty from early 2002 to 2010 end at Norvic International Hospital, Kathmandu. Results: Single vessel disease was most common (69.06%) followed by double vessel disease (25.84%) and triple vessel disease (5.10%). Left Anterior Descending artery was most frequently affected (56.0%) followed by Left Circumflex Artery (34.2%) and Right Common Artery (31.4%). Left Main coronary artery was found to be severely stenosed in 0.4% cases. Conclusion: The study has shown that the most Nepalese patients presented with single vessel disease with Left anterior descending as the most frequent culprit artery.
