Background ÃÆ'Æ'Æ’ÃÆ'†â€™ÃÆ'Æ'â€Ã...¡ÃÆ'‚¢ÃÆ'Æ'Æ’ÃÆ'¢â‚¬Ã...¡ÃÆ'Æ'¢ÃÆ'¢â‚¬Ã...¡ÃÆ'‚¬ÃÆ'Æ'Æ’ÃÆ'¢â‚¬Ã...¡ÃÆ'Æ'¢ÃÆ'¢â€Ã...¡Ã‚¬ÃÆ'‚ The objective of the study is to compare the outcome of patients who underwent valvular heart surgery with and without the use of pulmonary function test as part of preoperative risk assessment tool.

Study design: Prospective cross sectional study

Study setting and time period: All patients admitted at the Philippine Heart Center from August 2005 to December 2005 who underwent valvular heart surgery were risk stratified by Shapiro's risk stratification and modified Shapiro's risk stratification.

Results ÃÆ'Æ'Æ’ÃÆ'†â€™ÃÆ'Æ'â€Ã...¡ÃÆ'‚¢ÃÆ'Æ'Æ’ÃÆ'¢â‚¬Ã...¡ÃÆ'Æ'¢ÃÆ'¢â‚¬Ã...¡ÃÆ'‚¬ÃÆ'Æ'Æ’ÃÆ'¢â‚¬Ã...¡ÃÆ'Æ'¢ÃÆ'¢â€Ã...¡Ã‚¬ÃÆ'‚ A total of 37 patients who underwent valvular heart surgery were enrolled. The mean age of the subjects was 37 +/- 10 years. Most of the subjects had mitral valve defects. Seventy percent were extubated within 24 hours, while 6 subjects (16.2 percent) were extubated within 24-48 hours after surgical procedure. One was extubated more than 48 hours after surgical procedure. Twenty one subjects or 56.8 percent developed various complications from cardiac surgeries while 43.2 percent experienced no complications from the surgical procedures. Most subjects (14) developed cardiovascular complications rather than (8) pulmonary complications. The sensitivity and specificity based on the shapiros's stratification showed 88.89 percent and 3.12 percent respectively while based on modified shapiro's risk stratification show 55.56 percent and 62.5 percent respectively.

Conclusion ÃÆ'Æ'Æ’ÃÆ'†â€™ÃÆ'Æ'â€Ã...¡ÃÆ'‚¢ÃÆ'Æ'Æ’ÃÆ'¢â‚¬Ã...¡ÃÆ'Æ'¢ÃÆ'¢â‚¬Ã...¡ÃÆ'‚¬ÃÆ'Æ'Æ’ÃÆ'¢â‚¬Ã...¡ÃÆ'Æ'¢ÃÆ'¢â€Ã...¡Ã‚¬ÃÆ'‚ This study showed that pulmonary function test can be an optional tool rather than an essential part of the preoperative assessment tool in cardiac patient undergoing valvular heart surgery.
