Real-World Evaluation of a Pharmacoinvasive Strategy for STEMI in Latin America: A Cost-Effective Approach with Short-Term Benefits.

Purpose: While pharmacoinvasive strategy (PI) is a safe and effective approach whenever access to primary percutaneous intervention (pPCI) is limited, data on each strategy's economic cost and impact on in-hospital stay are scarce. The objective is to compare the cost-effectiveness of a PI with that of pPCI for the treatment of ST-elevation myocardial infarction (STEMI) in a Latin-American country. Patients and Methods: A total of 1747 patients were included, of whom 470 (26.9%) received PI, 433 (24.7%) pPCI, and 844 (48.3%) NR. The study's primary outcome was the incremental cost-effectiveness ratio (ICER) for PI compared with those for pPCI and non-reperfused (NR), calculated for 30-day major cardiovascular events (MACE), 30-day mortality, and length of stay. Results: For PI, the ICER estimates for MACE showed a decrease of $-35.81/per 1% (95 confidence interval, -114.73 to 64.81) compared with pPCI and a decrease of $-271.60/per 1% (95% CI, -1086.10 to -144.93) compared with NR. Also, in mortality, PI had an ICER decrease of $-129.50 (95% CI, -810.57, 455.06) compared to pPCI and $-165.27 (-224.06, -123.52) with NR. Finally, length of stay had an ICER reduction of -765.99 (-4020.68, 3141.65) and -283.40 (-304.95, -252.76) compared to pPCI and NR, respectively. Conclusion: The findings of this study suggest that PI may be a more efficient treatment approach for STEMI in regions where access to pPCI is limited or where patient and system delays are expected.

Assessment of Atypical Cardiovascular Risk Factors Using Single Photon Emission Computed Tomography in Mexican Women.

BACKGROUND: Ischemic heart disease (IHD) is a health care problem in women that increases morbimortality, particularly in developing countries. There is limited information regarding atypical risk factors associated with IHD in Mexican women. AIM: To explore risk factors in women that could contribute to IHD and myocardial dysfunction using the single photon emission computed tomography (SPECT) myocardial perfusion study (MPS). METHODS: We designed a cross-sectional study in which we evaluated atypical and typical risk factors using a clinical questionnaire. We performed a SPECT-MPS to evaluate the presence of ischemia/infarction, decreased left ventricular ejection fraction, systolic dyssynchrony and diastolic function by peak filling rate and time to peak filling rate. RESULTS: 172 women were included, 64 with IHD. Adverse events during pregnancy (premature birth and miscarriage), rheumatoid arthritis, gynecological conditions (menopause and age of first menstruation) and low educational level, together with previously known typical risk factors were associated with infarction or ischemia and ventricular dysfunction. Potential associated factors for systolic dyssynchrony were rheumatoid arthritis (OR: 2.90, 95% CI: 0.95-8.66, p = 0.054) and history of premature birth (OR: 0.13, 95% CI: 0.01-0.66, p <0.01). Although those women with arterial hypertension and smoking shown an increased risk for dyssynchrony, these factors were not statistically significant. Low-educational level (OR 2.16, 95% CI 1.1-4.18, p = 0.019) was associated with decreased peak filling rate. CONCLUSION: The presence of atypical risk factors in women could lead to decreased myocardial function, particularly in women at risk of developing IHD.

[Historical and social perspective from the 64-65 Mexican medical movement]. / Perspectiva histórica y social del Movimiento Médico de 1964-1965 en México.

The Mexican Medical Movement from 1964-1965 constitutes an important event from the rising urban middle-class, besides it was the first time medical doctors claimed for fair working conditions. The background of this movement is the so-called Crisis of 1958, which included the Movements from the educators union, oil workers union, telegraph workers union and the railroad workers union. The conflict began because interns and residents from the "Hospital 20 de Noviembre" would not get a payment at the end of the year, so on November 26th, 1964, the movement started. The Asociación Mexicana de Médicos Residentes e Internos (AMMRI) was created and their demands were the following: 1) Full working site restitution without retaliations, 2) Legal examination of the scholarship-contract terms, in order to get annual, renewable and progressive contracts, and a fixed salary with the usual working-hours and characteristics of each institution, 3) To have preference to get an adscription at the hospital where the resident studied, 4) Active participation from the resident in the elaboration of the academic plans, and 5) Resolution of each hospital's problems. This movement had social impact for Mexico's contemporary life, nevertheless some of the demands are still unchanged among medical residents.

El movimiento médico mexicano de 1964-1965 constituyó parte del primer despertar de la clase media urbana, además de haber sido la primera vez que los médicos reclamaron condiciones de trabajo justas. Como antecedente se tiene la llamada crisis de 1958, la cual incluyó los movimientos: revolucionario del Magisterio, del Sindicato de Trabajadores Petroleros, de la Alianza de Telegrafistas, y del Sindicato de Trabajadores Ferrocarrileros de la República Mexicana. El comienzo del conflicto médico se debió a que los residentes e internos del Hospital 20 de Noviembre del hoy Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE) no recibieron su aguinaldo, por lo que el 26 de noviembre de 1964 inició el paro, a partir del cual se formó la Asociación Mexicana de Médicos Residentes e Internos (AMMRI), cuyas demandas fueron: 1) Restitución total en sus puestos, sin represalias, 2) Revisión legal y cambio de los términos del contrato-beca, en el sentido de lograr contratos de trabajo anuales, renovables y progresivos, con el horario y características acostumbrados en cada institución además de determinación de sueldos base, 3) Preferencia para ocupar plaza de médico adscrito a los residentes egresados de las propias instituciones, 4) Participación activa del residente en la elaboración de los planes de enseñanza, y 5) Resolución de los problemas de cada hospital. Este movimiento, aunque tuvo repercusiones sociales para la vida contemporánea en México, a 50 años de su inicio, algunas de las demandas siguen sin ser resueltas para los médicos residentes.

Increased Cardiovascular Risk Using Atherogenic Index Measurement Among Healthcare Workers.

BACKGROUND AND AIMS: Cardiovascular diseases are one of the leading causes of death worldwide. This burden of disease is particularly high among healthcare workers. The aim of the study was to identify determinants that increase atherogenic index among healthcare workers. METHODS: In 1,678 healthcare workers, cardiovascular risk factors were analyzed: body mass index, waist-to-hip ratio, systolic and diastolic blood pressure, glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. Atherogenic index was calculated and determinants were identified. RESULTS: Mean (SD) age was 41.2 (8.4) years; body mass index 28.4 (4.8); waist-hip-ratio 0.88 (0.07); glucose 96.6 (22.2) µg/dL; TC 195.3 (50.3) mg/dL; HDL 49.0 (16.3) mg/dL; LDL 112.7 (35.0) mg/dL; triglycerides 171.7 (121.2) mg/dL; and atherogenic index 3.3 (1.5). Overweight and obesity prevalence was 77.2%. In the multiple linear regression model, the coefficients for AI were being a physician ß = 0.381, male gender = 0.443, BMI ß = 0.35, waist-to-hip ratio ß = 2.15, age = 0.014, and triglycerides ß = 0.915. CONCLUSIONS: The main contributors to atherogenic index increase were male sex, increased age, waist-to-hip ratio increase, overweight and obesity, high triglyceride levels and working as a physician. Although waist-to-hip ratio was the most powerful determinant, the physician occupational category added risk factors such as stress and adverse psychosocial working conditions, which may potentiate cardiovascular diseases.
