Application of simplified strategy to diffuse long lesions in the elderly

Abstract

Objective To evaluate the clinical efficacy of the simplified strategy in the treatment of diffuse long lesions in the elderly. Methods Two hundred and forty patients over 75 years old with diffuse long coronary artery disease and successfully implanted stents were divided into two groups according to whether the stent placement was completed or limited. The clinical features, pathological features, percutaneous coronary intervention (PCI) status and long-term prognosis of the two groups were observed. The success rates of angiography and surgery were compared between the two groups. The medication was followed up. The major adverse cardiovascular events (MACE) and all-cause mortality were compared between the two groups at 1 year after surgery. Results There was no significant difference between the two groups in cardiac death [1.56%(2/128) vs. 1.87%(2/107)], non-lethal acute cardiac muscle infarction (AMI) [1.56%(2/128) vs. 2.80%(3/107)], all-cause death [4.69%(6/128) vs. 4.67%(5/107)], revascularization of target vessels [2.34%(3/128) vs. 5.61%(6/107)] and angina pectoris recurrence [4.69%(6/128) vs. 7.47%(8/107)], P > 0.05. The difference between the two groups was statistically significant only in the follow-up of coronary angiography [18.75%(24/128) vs. 8.41%(9/107)], P < 0.05. Conclusions The long diffuse coronary artery lesions in the elderly can be implanted with point stents by simplified strategy. The long-term clinical effect is generally satisfactory.
