ABSTRACT
ABSTRACT Objective: to demonstrate scientific evidence on incidence and factors associated with contrast-induced nephropathy in patients undergoing percutaneous coronary intervention. Methods: an integrative review carried out in the VHL, PubMed, VHL Regional Portal and SciELO databases, of articles published between 2014 and 2019. Results: the sample consisted of five original articles, two cohorts, two control cases and a clinical trial. The incidence of contrast-induced nephropathy ranged from 6% to 24%. It stands out among patients with advanced age, male gender, diabetes mellitus, systemic arterial hypertension, volume of contrast infused and osmolarity. Intravenous hydration, sodium bicarbonate, ascorbic acid and statin were important prophylactic agents. Conclusion: this study envisioned the main risk factors for contrast-induced nephropathy in patients undergoing percutaneous coronary intervention and elucidated preventive measures that guide multidisciplinary health care aiming at a quality and safe care.
RESUMEN Objetivo: demostrar evidencia científica sobre la incidencia y factores asociados a la nefropatía inducida por contraste en pacientes sometidos a intervención coronaria percutánea. Métodos: revisión integrativa, realizada en las bases de datos BVS, PubMed, Portal Regional BVS y SciELO, de artículos publicados entre 2014 y 2019. Resultados: la muestra estuvo conformada por cinco artículos originales, dos cohortes, dos casos-controles y un ensayo clínico. La incidencia de nefropatía inducida por contraste osciló entre el 6% y el 24%. Destaca entre los pacientes con edad avanzada, sexo masculino, diabetes mellitus, hipertensión arterial sistémica, volumen de contraste infundido y osmolaridad. La hidratación intravenosa, el bicarbonato de sodio, el ácido ascórbico y las estatinas fueron importantes agentes profilácticos. Conclusión: este estudio visualizó los principales factores de riesgo de nefropatía inducida por contraste en pacientes sometidos a intervención coronaria percutánea, dilucidando las medidas preventivas que orientan la atención de salud multiprofesional con el objetivo de una atención de calidad y segura.
RESUMO Objetivo: demonstrar evidências científicas sobre incidência e fatores associados à nefropatia induzida por contraste em pacientes submetidos à intervenção coronária percutânea. Métodos: revisão integrativa, realizada nas bases de dados BVS, PubMed, Portal Regional da BVS e SciELO, de artigos publicados entre 2014 e 2019. Resultados: a amostra foi composta por cinco artigos originais, duas coortes, dois caso-controle e um ensaio clínico. A incidência da nefropatia induzida por contraste variou de 6% a 24%. Destaca-se entre os pacientes idade avançada, sexo masculino, diabetes mellitus, hipertensão arterial sistêmica, volume do contraste infundido e osmolaridade. Hidratação endovenosa, bicarbonato de sódio, ácido ascórbico e estatina foram importantes agentes profiláticos. Conclusão: este estudo vislumbrou os principais fatores de risco para a nefropatia induzida por contraste em pacientes submetidos à intervenção coronária percutânea, elucidando medidas preventivas que orientam o cuidado multiprofissional em saúde visando uma assistência de qualidade e segura.
ABSTRACT
Objective To evaluate the safety,efficiency and short-term results of cutting balloon coronary angioplasty.Method This procedure was performed on 63 lesions in 52 patients (male 94%,age 57?9 years).Results The overall procedural success rate for the cutting balloon angioplasty without predilation were 92.1%.Seven out of 9 cases of total occluded lesions had satisfactory results.Two cases of in-stent restenosis were also treated with CB successfully.Forty-three lesions were treated with cutting balloon followed by stents insertion.In 20 lesions treated with the cutting balloon alone,there was a marked reduction in the luminal stenosis from 78.8?11.6% to 7.2?5.6%.One patient developed pericardial tamponade 3 hours after cutting balloon angioplasty,which was resolved with pericardiocentesis.No severe dissection,no abrupt coronary closure,no emergency bypass surgery and acute myocardial infarction occurred.During 6 to 2 months' follow-up,only one patient treated by cutting balloon alone experienced angina pectoris and coronary angiography showed a restenosis, there were no further cardiac event.Conclusion Cutting balloon coronary angioplasty is a safe and effective interventional therapy with a high success rate and satisactory short-term results.
