Objetivo: Evaluar la asociación entre la exposición crónica a grandes alturas y la presencia de ectasia coronaria (EC) en pacientes con infarto de miocardio con elevación del segmento ST (IMCEST). Materiales y métodos: Estudio retrospectivo de casos y controles pareados. Se evaluó la relación entre la presencia de ectasia coronaria y la exposición crónica a gran altura, teniendo en cuenta variables intervinientes como hipertensión arterial, diabetes mellitus, dislipidemia, tabaquismo y valores de hematocrito. Se excluyeron pacientes con patología inflamatorias crónicas, enfermedad pulmonar obstructiva crónica y revascularizados previos. Se aplicó regresión logística multivariada para obtener el valor del OR y sus respectivos intervalos de confianza. Resultados: 18 casos y 18 controles fueron estudiados, la mayoría fueron varones con edad promedio de 65 años. Un 36% de l...

Evaluación de las características de pacientes con síndrome coronario agudo con elevación del segmento ST asintomáticos con más de 12 horas de evolución y si existe o no beneficio de la terapia invasiva versus el manejo médico en el seguimiento. Se hizo un estudio retrospectivo, de cohortes, incluyendo a todos los pacientes admitidos en el Instituto Nacional Cardiovascular (INCOR) desde enero 2012 a diciembre 2014, se comparó los eventos adversos a 6 y 12 meses de seguimiento del grupo en terapia invasiva versus manejo conservador.

Objective. To evaluate the association between chronic exposure to high altitude and the presence of coronary ectasia (CE) in patients with ST-segment elevation myocardial infarction (STEMI) treated in a highly specialized cardiovascular reference hospital in Peru. Materials and methods. Retrospective matched case-control study. The cases were patients with CE and controls without CE. The relationship between CE and chronic exposure to high altitude was evaluated considering intervening variables such as arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and hematocrit values. Patients with chronic inflammatory pathologies, chronic obstructive pulmonary disease, and previous revascularization were excluded. Multivariate logistic regression was applied to obtain the OR value and their respective confidence intervals. Results. Eighteen cases and 18 controls were studied, most...

Objective: To determine the factors associated and measure the socioeconomic inequalities in people with undiagnosed hypertension in Peru. Materials and methods: An observational, cross-sectional, analytical study was performed using data from the 2019 Demographic and Family Health Survey (ENDES, acronym in Spanish) database. The dependent variable was the presence of undiagnosed hypertension (mean systolic blood pressure ≥140 mmHg and/or mean diastolic blood pressure ≥90 mmHg in the two blood pressure measurements and with no prior diagnosis of hypertension by a health care professional). Adjusted prevalence ratios were estimated to determine the factors associated with undiagnosed hypertension. The socioeconomic inequality in undiagnosed hypertension was estimated using concentration curves and the Erreygers concentration index. Results: 67.2% of 3697 persons with hypertension had ...
