Influência dos fatores de risco das doenças cardiovasculares no tempo de ventilação mecânica em pacientes submetidos à revascularização do miocárdio

Abstract

Objective: To determine whether there is relationship of modifiable risk factors and non-changeable cardiovascular disease (CVD) with time for invasive mechanical ventilation in patients post-operative coronary artery bypass grafting (CABG). Methods: This is a cross-sectional and quantitative. Held in the Coronary Intensive Care Unit (Utica) of the Hospital of the Federal District. We analyzed the charts of 9 patients after myocardial revascularization, from January to September 2011, where were the data related to risk factors with the parameters and time of invasive mechanical ventilation. Results: Among the non-modifiable risk factors has a mean age of 62.67 ± 2.10 years, of whom 66% were male and 33% female, 55% reported family history of CVD. All presented as a modifiable risk factor hypertension (SAH), 88% sedentary, 77% had dyslipidemia (DLP), 66% smokers, 55% had diabetes mellitus (DM) and 11% obese. At the time VM <24 hours <48 hours and> 48 hours, there evolved for extubation of two patients in each category, the occurrence of one death and two remained on mechanical ventilation. In the current study is only a statistically significant, the correlation between family history of CVD and extubation with p < 0.03 considering a significance level of p < 0.05. Conclusion: With the sample in question the only factor that was correlated with time to extubation was the family history for CVD.
