[Interests and limitations of percutaneous coronary intervention strategy in nonagenarian patients: A single center experience]

Abstract

Aim: To expose our center results in the angioplasty in nonagenarians and to evaluate its effectiveness but also the MACEs and the mortality in the short and long term.

Methods: A retrospective study of 98 patients admitted to the Antibes hospital center from November 2013 to September 2018.

Results: The median age was 91.8 [90.8-93.4]. 52.6% was male. 9.7% of the patients had a polyvascular site. 50.6% of patients had moderate renal failure. The radial approach was used in 88.4% of cases. 21.6% of patients had tri-truncal lesions, while 46.4% were monotruncular, LAD artery was the culprit artery in 67% of cases. One stent per lesion was used in the majority of cases. Our successful rate was 90%. After angioplasty, 96% of the patients underwent double antiaggregation platelet therapy, 74.4% under clopidogrel. The presence of arrhythmias before angioplasty, the femoral approach, the coronary dissection and cardiogenic shock after angioplasty were predictors of short- and long-term mortality. Diabetes, history of myocardial infarction, impaired left ventricular ejection fraction, calcified coronary lesions, occurrence of arrhythmias or signs of heart failure on post-procedure were predictors of MACE occurrence.

Conclusions: This study demonstrates that angioplasty in selected population of nonagenarians is perfectly feasible with a good risk/benefit ratio and specifies the different predictors of MACE, both short- and long-term mortality.
