Retrospective analysis of clinical and pulmonary data in valve surgery
Abstract
Objectives: The purpose of the current investigation was to assess the effect of surgery on clinical and pulmonary data in valve surgery (VS).
Methodology: As a result of retrospective review performed between January and December, 2004, 30 patients’ data were studied. Preoperative patients’ characteristics, cardiac profiles, coronary risk factors, operative and postoperative data, pulmonary function tests (PFT) and respiratory muscle strength (RMS) measurements were collected.
Results: Mean values of all predicted values of PFT and RMS were normal preoperatively. There was a significant decrease in FVC (p < 0.0001), FEV1 (p < 0.0001), FMF (p < 0.0063), FEF (p < 0.002), PImax (p < 0.0001), and PEmax (p < 0.0126) after surgery. Patients with atrial fibrillation (AF) had longer periods of intensive care unit (ICU) (p < 0.0001). NYHA significantly correlated with preoperative PFT parameters [FVC (p=0.0085), FEV1 (p=0.0043), FMF (p=0.0055)] and postoperative ICU stay (p=0.0426). Postoperatively, PImax significantly correlated with FVC (p=0.0167) and FEV1 (p=0.0143).
Conclusions: The extent of functional status affected pulmonary functions in patients with valve disease. Postoperative AF had significant negative impact on ICU stay.
