Preditores de letalidade hospitalar em pacientes com insuficiência cardíaca avançada

Abstract

Patients admitted to an intensive care unit due to decompensated heart failure have high in-hospital lethality. In this study, variables recorded at admission, such as previous stroke, atrial fibrillation, hyponatremia, renal failure, and age > 70 years were predictors of in-hospital lethality.

Perfil epidemiológico, clínico e terapêutico da insuficiência cardíaca em hospital terciário

“…Ischemic cardiomyopathy was the least frequent etiology (17 cases -11.8%), in contrast with other studies 7,12,14,15 that identified it as the main cause of HF among the patients. The study by Rassi et al 12 , which evaluated survival and prognostic factors in systolic HF and was carried out in the state of Goiás, observed a higher frequency of ischemic cardiomyopathy, followed by chagasic cardiomyopathy.…”

Mortalidade por insuficiência cardíaca: análise ampliada e tendência temporal em três estados do Brasil

“…It must also be mentioned that the diastolic HF, also called HF with preserved left ventricular function, can represent up to 50% of the cases of hospitalizations due to HF 10,30 and it is not represented by any code in the ICD-10.…”

“…Most of the publications on the importance of HF as the cause of death in Brazil are derived from cohort studies 9,10 or related to hospital mortality, based on the data available at the Brazilian Public Health System (SUS) regarding hospitalizations in public hospitals or those hired by the system 11,12 . In Brazil, HF was the third cause of hospitalization due to clinical causes through SUS/MH(Ministry of Health) from 1992 to 2002, with percentages of hospitalizations in relation to the total number of hospitalizations that varied from 3%-4%, with lethality rates of 5%-7% at hospital admissions 2 .…”

A classe da NYHA tem relação com a condição funcional e qualidade de vida na insuficiência cardíaca

“…Cross-sectional study, a sample of 66 patients (45 men). It applied a form of standardized assessment, spirometry, manovacuometry, of the six minute walk test (6MWT) and questioning the quality of life Short-Form 36 (SF-36 5,6 . A partir da diminuição do débito cardíaco e da fração de ejeção, a IC causa baixa tolerância aos exercícios com acentuadas respostas metabólicas e respiratórias 7 , o que leva o sujeito à inatividade, ocasionando atrofia muscular que está associada à fadiga e ao decréscimo na força muscular [8][9][10] .…”
