- ItemFactores determinantes en la aparición de fibrilación auricular post-cirugía de revascularización miocárdica. Un estudio prospectivo(2007) Baeza Vergara, Ricardo Gabriel; Garayar Pulgar, Bernardita; Morán Velásquez, Sergio; Zalaquett Sepúlveda, Ricardo; Irarrázaval Llona, Manuel José; Becker Rencoret, Pedro Antonio; Viviani García, Paola; Ferrada, Marcela; Corbalán Herreros, RamónBackground: Atrial fibrillation (AF) is a relevant complication after coronary artery bypass grafting (CABG). However there is controversy regarding possible contributing factors. Aim: To study the incidence of AF, its risk factors and its repercussion on hospital stay and charges, in patients undergoing CABG. Material and methods: We prospectively collected information from all patients undergoing CABG in our institution, including demographic, surgical and laboratory variables. Exclusion criteria were chronic AF, recent onset AF and patients who needed additional surgical procedures. The primary endpoint was the incidence of AF during the hospital stay. Secondary endpoints were hospital length of stay and hospital charges. Results: We included 250 patients aged 62±9 years (199 males) in the analysis. Incidence of AF was 22% (54 patients). Multivariable analysis showed that age (Odds Ratio (OR) =1.10), previous CABG (OR =9.39), previous use of ACE inhibitors (OR =3.28) and aortic clamp >57 minutes (OR =3.97) were significantly associated with an increased risk of postoperative AF. Previous use of beta-blockers was associated with risk reduction (OR =0.43). Patients who developed AF had a longer hospital stay (p <0.001) and higher hospital charges (p =0.003). Conclusion: AF is a frequent complication in patients undergoing CABG. Risk factors are age, time of aortic clamp, previous CABG and ACE inhibitors. Beta-blockers may prevent its occurrence. Furthermore, AF has a negative impact on both hospital stay and hospital charges
- ItemInfluencia del sistema de salud de procedencia y otros factores en el resultado del reemplazo valvular mitral(2013) Morán, Sergio; Muñoz Contreras, María Cecilia; Garayar Pulgar, Bernardita; Zalaquett Sepúlveda, Ricardo; Irarrázaval Llona, Manuel José; Becker Rencoret, Pedro Antonio; González Foretic, Rodrigo Vicente
- ItemInsuficiencia renal aguda secundaria a rabdomiolisis como manifestación de infección por SARS-CoV-2(Sociedad Médica Santiago, 2021) Pérez, Javier; Sánchez Zagal, Sebastián Antonio; Sepúlveda Palamara, Rodrigo Andrés; Vera Alarcón, María Magdalena; Mery Ponce, Pablo Agustin; Garayar Pulgar, Bernardita; Jalil Milad, Roberto DanielSARS-CoV-2 infection has a wide spectrum of clinical manifestations secondary to the impairment of different organs, including kidney. Rhabdomyolysis is produced by disintegration of striated muscle and the liberation of its contents to the extracellular fluid and bloodstream. This may produce hydro electrolytic disorders and acute kidney injury. We report a 35-year-old female with a history of SARS-CoV-2 infection who was hospitalized because of respiratory failure and developed renal failure. The etiologic study showed elevated total creatine kinase levels and a magnetic resonance imaging confirmed rhabdomyolysis. The patient required supportive treatment with vasoactive drugs, mechanic ventilation and kidney replacement therapy. She had a favorable evolution with resolution of respiratory failure and improvement of kidney function.
- ItemRemodelado auricular derecho y niveles plasmáticos de Galectina-3 se relacionan con la capacidad funcional de pacientes con hipertensión arterial pulmonar(2016) Gabrielli, Luigi; Verdejo Pinochet, Hugo; Ocaranza, María Paz; Sepúlveda Varela, Pablo Andrés; Baraona Reyes, Fernando Exequiel; Salinas, Manuel; Saavedra, R.; Llevaneras, Silvana; Quiroga Lagos, Clara Rosa; Garayar Pulgar, Bernardita; Lavandero, Sergio; Castro Gálvez, Pablo Federico
- ItemResults of the surgical management of abdominal aortic eurysms in 80 patients over 80 years of age(2003) Valdés E., Francisco; Bergoeing Reid, Michel Paul; Kramer, Albrecht; Mertens Martin, Renato; Canessa, Roberto; Lema F., Guillermo; Garayar Pulgar, Bernardita; Urzua Urzua, JorgeBackground: Abdominal aortic aneurysms (AAA) may be lethal unless appropriately and timely treated. Since age is a surgical risk, octogenarians are usually not considered as candidates for surgical intervention. Aim: To asses surgical complications and mortality in octogenarians treated for AAA. Subjects and Methods: Patients aged 80 years older, treated consecutively between 1984-2001 were retrospectively analyzed. Results: Sixty one patients were male, and their age ranged from 80 to 95 years. All were treated with open surgery. The operation was elective in 58 and as an emergency in 22 patients (symptomatic or ruptured AAA). Aortic diameter was 6.8+/-1.4 cm in asymptomatic patients and 7.7+/-1.8 cm in emergency cases (p=0.024). Thirty days postoperative mortality was 5.1% in elective surgery compared to 40.6% in emergency operations (p < 0.01). Five years survival rate was 44.7% in asymptomatic patients compared to 10.4% in the emergency cases (p < 0.023). Conclusions: Elective surgery for asymptomatic AAA can be performed with low operative mortality in octogenarians. However, surgery in emergency cases has an 8 fold increase in risk. Accordingly, octogenarian patients should be considered for elective AAA repair in a selective basis.
