Abstract


AIMS: Coronary diseases are the main cause of mortality in the West. Several factors may affect successful percutaneous revascularization, such as the type of stent used or the cardiovascular risk factors associated with the patient. The systolic function of the left ventricle has usually been disregarded in restenosis scores. Our aim is to evaluate restenosis while taking into account the kind of stent used and the systolic function of the left ventricle. METHODS: A prospective, observational and population study. A total of 209 patients with percutaneous revascularization were recruited between March 2011 and January 2013 and monitored every six months. Their clinical data was collected and transthoracic echocardiograms were performed. RESULTS: The average age was 67±11 years old, 64.6% were men. Regarding cardiovascular risk factors, 55.6% were diabetics, 84.2% had hypertension and 81.3% were dyslipemic. A combined revascularization strategy was more often used among the general population than in the diabetic subgroup. The diabetic patient subgroup received a larger number of drug-coated stents. The systolic function was present among 84% of the general population compared to 80% of the diabetic patient subgroup. Both the general population as well as the diabetic patient subgroup presented a significant decreased sistolic function of the left ventricle when the restenosis rate was greater (p<0.001 respectively). Similarly, we observe that there is a significant connection between the ejection fraction and the emergence of a new symptoms. CONCLUSION: The non-combined strategy was used more frequently in the diabetic population with the use of a superior drug-eluting stent Furthermore, systolic function evaluation stratifies the restenosis risk, especially in patients with a depressed ventricular function.
