ABSTRACT

We evaluated immediate and mid-term clinical and angiographic results in diabetic patients with percutaneous coronary intervention with deployment of drug eluting stents. METHODS: Between November of 2004 and June of 2005 percutaneous coronary interventions were performed 860 with the deployment of 112 drug eluting stents to 42 diabetic patients. The mean of stents was 2.6 per patient, and the type of drug eluting stent was paclitaxel in 60% and sirolimus in 40%. The average of age was 51.2 +/- 9.6 years old. The gender was male in 25 (60%) of patients and female in 17 (40%). The indication of coronary angiography was unstable angina in 15 (35%) patients and stable angina in 27 (65%). There was history of anterior myocardial infarction in 20 (47%), inferior myocardial infarction in 8 (20%) and multiple vessel disease in 16 (38%). The stenosis severity of the lesion was 85.9% +/- 12.2% and the left ventricular function was (55 +/- 10). The hospital stay was 7 +/- 5.4 days. RESULTS: Both clinical and angiographic immediate success was 100%. The average follow was 7.6 +/- 3.3 months in 34 patients (80.9%). The target lesion revascularization (TLR) was 7.1%. (3 patients). Death, myocardial infarction or reinfarction (0%). COMPLICATIONS: One patient (2.3%) developed contrast induced nephropathy. CONCLUSIONS: These results suggest that the use of drug eluting stents (paclitaxel or sirolimus) in diabetic patients has a high rate of success with good angiographic and clinical results and with a low rate of complications or restenosis in this high risk group of patients.

ABSTRACT

Since the last decade, percutaneous balloon mitral valvuloplasty with Inoue catheter is considered the treatment of choice for selected patients (mobile valve, no calcification and minimal subvalvular disease) with rheumatic mitral stenosis. OBJECTIVE: We present the seven-year follow-up experience of 456 patients treated with this technique in the catheter laboratory of the Cardiology Hospital in National Medical Center SXXI. MATERIAL AND METHODS: It is a retrospective, transversal and observational study performed with data obtained from January 1994 and December 2000, with a follow-up of 58.5 +/- 26.6 months (range 12-96 mean 22). RESULTS: We achieve an initial success of 82.8%, improvement of initial mitral valve area from 0.9 +/- 0.1 to 1.8 +/- 0.3 cm2, with a gain area from 88 to 106% (p < or = 0.001). At the end of the follow-up, the mean valvular area was maintained in 1.7 +/- 0.3 cm2 in 69.8% of the cases. We found a significant reduction of transmitral gradient and of the pulmonary artery systolic pressure immediately after the procedure; 93.1% of patients were in NYHA functional class II at the end of the follow-up, 11.6% presented complications (mitral regurgitation as the most important), in 15.9% of them, due to leaflet rupture, but only 9.1% corresponded to severe grade Ill-IV. COMPLICATIONS: Only one patient died due to septal perforation; 93.8% of the patients remained free of major cardiac events at the end of the study. Only 6.1% of the patients required surgery at the end of the follow-up; 5.5% were in functional class NYHA Ill-IV and restenosis occurred in 14.6%. CONCLUSION: Percutaneous balloon mitral valvuloplasty with Inoue balloon catheter is a safe and effective technique for treating rheumatic mitral stenosis with Wilkins score < 10, with minimal risk and complications and offers good life expectancy with absence of major cardiac events in > 90%. From these patients, 93.1% remained in NYHA-II or -I functional class and the incidence of restenosis decreased.

Material y métodos: Tipo de estudio; retrospectivo, observacional, transversal y descriptivo con seguimiento a 30 días. De enero de 2001 a julio de 2004 se realizaron 3,238 procedimientos de ACTP con aplicación de stent a pacientes con diagnóstico de cardiopatía isquémica por aterosclerosis coronaria, se seleccionó a 32 pacientes que representan el 0.98%, con edad de 47 a 79 años promedio de 63, 24 (75%) del sexo masculino, con hipertensión arterial sistémica 29 (90.6%), diabetes mellitus 18 (56.3%), hipercolesterolemia 11 (34.4%), tabaquismo 24 (75%), con antecedentes de angina inestable 9 (28.1%) y con infarto miocardio previo 2 (6.3%). La localización del IAM: anterior extenso 14 (43.8%), anteroseptal en 6 (18.8%), postero-inferior en 5 (15.6%), Pl con extensión eléctrica y/o hemodinámica en VD en 4 (12.5%), lateral en 1 (3.1%). Se trombolizaron en un tiempo promedio 3.19 horas (rango 2-7) con estreptoquinasa 19 (59.4%) y con rTPA 13 (40.6%), la CPK-MB pico (U) promedio de 348 ± 240. Con Killip Kimball (KK) 1 en cinco (15.6%), II 16 (50%), III 5 (15.6%) y IV 6 (18.8%) éstos manejados con balón intraaórtico de contrapulsación. Resultados: Llevados a sala de hemodinamia en un tiempo de 6 a 24 h encontrando flujo TIMI 0 en 16 (50%), TIMI 1 en diez (31.2%), TIMI 2 en seis (18.8%), promedio de vasos enfermos de 1.9. Se implantó stent en 27 (84.3%). Éxito angiográfico post ACTP más stent TIMI 3 en 24 (75%). Complicaciones: En 9(28.1%), en 7 (21.8%) con no reflujo y en 1 (3.1%) disección de la arteria coronaria relacionada con el IAM, 6 (18.7%) que fallecieron, en 4 (12.5%) con choque cardiogénico; 3 (9.3%) la ACTPR fue fallida. Conclusión: La ACTPR es un procedimiento de alto riesgo y pese a ello es una buena alternativa de tratamiento en pacientes con trombólisis fallida.


The present study is aimed at describing the short-term assessment of clinical and angiographic results in patients with acute myocardial infarction treated with rescue percutaneous transluminal coronary angioplasty (RPTCA). Methods: We reviewed retrospectively, from January 2001 to July 2004, the interventional procedures performed in patients with coronary heart disease. From a total of 3,258 patients we selected 32 (0.98%) with acute myocardial infarction and failure of thrombolysis treatment, which were treated with RPTCA to relief the symptoms. Average age was 63 years (range 47-79), there were 24 men (75%); hypertension in 29 (90.6%); diabetes mellitus in 18 (56.3%); currently smoking 24 (75%); dyslipidemia in 11 (34.4%); unstable angina in 9 (28.1%); previous myocardial infarction in 2 (6.3%). The area related to the infarction was anterior and lateral in 14 (43.8%), anteroseptal in 6 (18.8%), postero-inferior in 5 (15.6%) with electric and hemodynamic involvement in 4 (12.5%), lateral in 1(3.1 %). Thrombolysis treatment was delivered in 3.19 hours (range 2-7 hours) with streptokinasein 19 (59.4%) and rTPA in 13 (40.6%). The evaluated serum marker was CPK-MB with the highest level of 348 ± 240 U/L. Killip Kimball (KK) class was established as follows: KKI in 5 (15.6%), II in 16 (50%), III in 5 (15.6%), and IV in 6 (18.8%). Patients with cardiogenic shock were treated with intra-aortic balloon counterpulsation. Results: Time between symptoms and arrival to the cath lab was 11 hours (range 6-24 hours). TIMI flow was: TIMI 0 in 16(50%). TIMI 1 in 10 (31.2%), TIMI 2 in 6 (18.8%). The number of vessels with a significant lesion was 1.9 (range 1-4). Stents were placed in 27 (84.3%) patients. Angiographic success post-angioplasty was achieved in 24 (75%); there were 9 complications (28.1%), no reflow in 7 (21.8%), coronary dissection in 1 (3.1%). Six patients died (18.7%) and 4 of them (12.5%) were in cardiogenic shock. Conclusion: RPT-CA is a high-risk procedure, being an acceptable treatment option for patients with thrombolysis failure.

ABSTRACT

La evaluación del estado nutricio del paciente cardiópata debe incluir las medidas y antropométricas, pruebas debe incluir las medidas antropométricas, pruebas de metabolismo orgánico y de inmunidad celular, Evaluamos el estado nutricio de 75 pacientes cardiópatas internados, se correlacionó con las clase funcional y la patología de base. Se encontraron 36 pacientes (48 por ciento) con estado nutricional normal, 24 (32 por ciento) con desnutrición leve, 12 (16 por ciento) con desnutrición moderada, 3 (4 por ciento) con desnutrición moderada, 3, (4 por ciento) con desnutrición severa, De 23 pacientes con cardiopatía isquemica, 25 por ciento estaban desnutridos, de 4 con cardiopatía hipertensiva 50 por ciento estaban desnutridos, en 4 pacientes, con cardiomiopatía el 75 por ciento cursó con desnutrición y en 7 pacientes con otras patologías cardiovasculares, el 83 por ciento tenía desnutrición. Existe correlación directa entre el grado de desnutrición y la clase funcional. No encontramos ningún paciente con clase funcional IV con buen estado nutricional, ni en los que tenían desnutrición leve

ABSTRACT

De febrero de 1995 a febrero de 1997 se colocaron 157 stents a 105 pacientes. La edad varió de 38 a 81 años (media 58), 83 del sexo masculino y 22 del femenino. En 66 (62.8 por ciento) se colocó un solo stent y en 39 (37.2 por ciento), de 2 a 6. Se colocaron 83 Palmaz/Schatz (P/S), 27 ACT-ONE, 18 Wiktor, 9 Gianturco Rubin (GR), 8 Wallstent, 6 XT-BARD y 6 microstents. La indicación fue de novo en 23.8 por ciento, 87.5 por ciento post ACTP fallida y 13.3 por ciento postreestenosis de ACT. La implantación fue exitosa en el 96.1 por ciento de los casos. Los primeros 32 casos fueron manejados con anticoagulación oral, al resto sólo se les administró aspirina y ticlopidina únicamente. Las complicaciones fueron 4.7 por ciento de los enfermos con trombosis aguda y 0.9 por ciento subaguda, tres de ellos desarrollaron un IM (2.5 por ciento); 2.8 por ciento complicaciones vasculares, 0.9 por ciento se enviaron a cirugía de urgencia y en 2.8 por ciento hubo mortalidad. Durante el seguimiento de 1 a 18 meses (media 7.7), se han recateterizado 35 pacientes, de 2 a 14 meses (m=5.6), 12 de ellos con reestenosis. Durante la redilatación, en dos casos hubo disección del TCI y fueron redilatados con balón satisfactoriamente. Un enfermo tuvo estenosis del stent y progresión de la enfermedad en otros vasos, por lo que se envió a cirugía electiva, y un enfermo presentó evidencia de IM en la zona correspondiente al sitio del stent, se trombolizó y el recateterismo tres días después mostró una estenosis del 50 por ciento. Los otros enfermos se encuentran asintomáticos o con pruebas de esfuerzo negativas. Este estudio confirma los beneficios de esta nueva tecnología como otra alternativa muy prometedora de revascularización miocárdica percutánea. Falta seguimiento a largo plazo para conocer la incidencia real de reestenosis en cada uno de los diferentes tipos de stent
