Evaluation of safety and efficacy of elective PCI in patients with cardiac insufficiency.

We analyzed the safety and the efficacy of the treatment with elective percutaneous coronary intervention (PCI) in patients with coronary heart disease complicated with cardiac insufficiency. We enrolled 217 patients diagnosed with chronic ischemic heart disease complicated with cardiac failure. According to the type of treatment they received, patients were divided into 3 groups: i) The conservative treatment group with 60 patients (they received standard medication); ii) the early PCI group with 82 cases (their condition was stabilized, surgical risk was assessed and PCI was taken as early as possible); and iii) the advanced PCI group with 75 cases (ischemic myocardium was corrected and then elective PCI was applied and for aggravated myocardial ischemia cases, PCI was applied after assessing the risk of surgery).
