ABSTRACT

Objective: The objective of PHASE-MX registry is to validate the efficacy and safety of the pharmacoinvasive strategy in comparison with percutaneous coronary intervention (PCI) in patients with acute myocardial infarction with ST segment elevation (STEMI) in a metropolitan region of Mexico. The primary outcome will consist of the composite of cardiovascular death, re-infarction, stroke and cardiogenic shock. Methods: The PHASE-MX registry will include a prospective cohort of patients with STEMI who received reperfusion treatment (mechanical of pharmacological) in the first 12 h after the onset of symptoms. The registry is designed to compare the efficacy and safety of primary PCI and pharmacoinvasive strategy. The simple size was calculated in 344 patients divided into two groups, with an estimated loss rate of 10%. Patients included in the PHASE-MX cohort will be followed for up to one year. Conclusion: In Mexico, only 5 out of 10 patients with STEMI have access to reperfusion therapy. Pharmacoinvasive strategy is takes advantage of the accessibility of fibrinolysis and the effectiveness of PCI. The present research protocol aims to provide information that serves as a link between information derived from controlled clinical trials and records derived from real world experience.


Objetivo: El objetivo del registro PHASE-MX es validar la eficacia y seguridad de la estrategia farmacoinvasiva en comparación con la angioplastia coronaria transluminal percutánea primaria (ACTPp) en pacientes con infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en una región metropolitana de México. El desenlace primario es el compuesto de muerte cardiovascular, reinfarto, accidente vascular cerebral y choque cardiogénico. Métodos: El registro PHASE-MX es una cohorte prospectiva de pacientes con IAMCEST que recibieron tratamiento de reperfusión (mecánico o farmacológico) en las primeras 12 horas desde el inicio de los síntomas, atendidos en el Instituto Nacional de Cardiología Ignacio Chávez. El análisis estadístico se basa en la no inferioridad de la estrategia farmacoinvasiva en comparación con la ACTPp. Se calcula un tamaño de muestra de 344 pacientes divididos en dos grupos (angioplastia primaria y estrategia farmacoinvasiva), considerada una tasa de pérdidas de 10%. Los pacientes incluidos en la cohorte PHASE-MX se seguirán durante un año. Discusión: En México, sólo 5 de cada 10 pacientes con IAMCEST tienen acceso al tratamiento de reperfusión. La estrategia farmacoinvasiva aprovecha la accesibilidad de la fibrinólisis y la efectividad de la ACTPp, por lo que podría resultar el método de elección en el tratamiento del IAMCEST en la mayoría de los casos. El presente protocolo de investigación pretende aportar información que sirva como enlace entre la información derivada de los estudios clínicos controlados y los registros derivados de la experiencia del mundo real.

ABSTRACT

BACKGROUND: Lung ultrasound (LUS) has emerged as a new tool for the evaluation of congestion in heart failure (HF); incorporation of LUS during follow-up may detect congestion earlier and prompt interventions to prevent hospitalizations. The aim of this study was to test the hypothesis that the incorporation of LUS during follow-up of patients with HF may reduce the rate of adverse events compared with usual care. METHODS: In this single-blinded, randomized controlled trial, patients were randomized into an LUS-guided arm or control arm. Patients were followed in 4 prespecified visits during a 6-month period. LUS was performed in every patient visit in both groups; however, LUS results were available for the treating physician only in the LUS group. The primary outcome was the composite of urgent HF visits, rehospitalization for worsening HF, and death from any cause. RESULTS: One hundred twenty-six patients were randomized to either LUS (n = 63) or control (n = 63) (age 62.5 ±â€¯10 years, median left ventricular ejection fraction 31%). The primary end point occurred in 30 (47.6%) patients in the control group and 20 (31.7%) patients in the LUS group (P = .041). LUS-guided treatment was associated with a 45% risk reduction in the primary end point (hazard ratio 0.55, 95% CI 0.31-0.98, P = .044), mainly driven by a reduction in urgent HF visits (hazard ratio 0.28, 95% CI 0.13-0.62, P = .001). No significant differences in rehospitalizations for HF or death were found. CONCLUSIONS: Incorporation of LUS into clinical follow-up of patients with HF significantly reduced the risk of urgent visits for worsening HF.
