ABSTRACT

Background: More than 30% ussually treated patients (pts) with coronary artery lesions corresponding in small coronary arteries. Method: From april 1995 to january 2004 which were attended in our hospital (CMNN HRE 34 IMSS), 453 pts attended with coronary angioplasty; To evaluate the safety, efficacy and the effects of the coronary artery ballon angioplasty (PTCA) and stenting immediate and follow up to 6 and 12 months in both groups diabetics and non diabetics patients (pts) the age average in our groups was 59.2 ± 6.5; 63% male and 34.8 female gender without demographic differences as hypertension disease (HD), diabetes mellitus (DM), dyslipidaemia (DLP), smoking and obesity. Results: The patients (pts) were divided in diabetic (DM), 178/454 39.20% and non diabetic groups (NDM) 276/454, 60.79%; as a mean while both divided into two kinds of interventional procedures utilized ballon angioplasty (TPCA), alone or stent implantation (st). Small vessel were defined as a those less than 2.8 mm, with oscilating diameters between 2.8 and 1.8 mm smaller the diabetic groups most frequently seen. The (NDm) showed better functional status for the firts 6 months treated with (TPCA) with P ≤ 0.0217. The diabetic (DM), pts were considered deleterious and in a high risk group to MACES. (DM) pts were presenting more MACES in 6 months and a following year compared with (NDM) pts P ≤ 0.0001. This group of pts with (St) implant showed with statistical bad prognosis about MACES in compared with those (NDM) treated even 6 months P ʹ 0.014 and following to a year with P ≤ 0.0001. MACES in (DM) pts treated with (St) vs (TPCA) alone were similar results in the first 6 months P ≤ 0.43 but adverse effects growing in a year follow up with MACES in (DM) (St) group with P ‹ 0.02. The (NDM) pts has a better prognosis maintaining a class I even treated with (TPCA) alone or with (St) implantation in compared with (DM) pts. The (TPCA) alone has better results in (DM) pts vs (St) implant in 6 months and a year follow up. The (NDM) most be treated with (St) implantation for better results for 6 months and a year follow up. The (DM) pts has a worst prognosis and a high incidence of MACES in compared with (NDM) pts. It seems that must received a (TPCA) procedure alone for small vessel disease vs Bare Stent implantation (BSt). Medicated stents investigation is not the purpose in the present study; could be the mattered in another trial.
