Echocardiographic studies were performed using an ACUSON Sequoia 512 ultrasound system. The study population consisted of 198 healthy subjects without cardiovascular or other systemic diseases and who were not taking any medications. The aim of the present study was to evaluate the impact of gender and healthy aging on estimated PCWP using a kinetics-tracking index in patients and in healthy subjects without hypertension. CVP monitoring can be used as a surrogate for PA catheter to follow changes in filling pressure in healthy individuals.Risk stratification in heart failure (HF) among patients and healthy subjects using pulmonary capillary wedge pressure (PCWP) is important for understanding when and why HF develops. Conclusion: CVP is highly correlated with PCWP over a wide range of filling pressures from young to elderly. The slopes were not significantly different between Young and Old (Table 1). 1).b) The slopes of the regression lines were statistically significantly higher at the increased preload pressures than those at decreased preload pressures in both Young and Old although this difference was very small clinically (Table 1). Results: a) Both Young and Old showed that PCWP was well correlated with CVP in individual data in conditions of increased preload, decreased preload, and over a large range of filling pressures (Table 1).These results were also confirmed in pooled data (Fig. These relationships were also examined individually and over our entire population. The relationships between CVP and PCWP were assessed at baseline and with increased and decreased preload. Filling pressures were then augmented with acute saline infusion by 15 and 30 ml/kg and repeat measurements were taken. After LBNP release, baseline measurements of CVP and PCWP were repeated. Repeat measurements were made at each level. Filling pressures were then reduced with lower body negative pressure (LBNP) sequentially by -15 and -30 mmHg. Mean CVP and PCWP were measured three times at the end of a quiet expiration and averaged. A PA catheter was inserted into the pulmonary artery via the median antecubital vein under fluoroscopic guidance. Methods: Thirty-four young healthy individuals (Young, age65 yrs) were recruited. The purpose of this study was to evaluate the relationship between CVP and PCWP under controlled conditions of increased and decreased preload. The relationship between CVP and PCWP has never been investigated under varying preloads at supine rest in healthy individuals under experimentally controlled conditions. CVP monitoring is important from the view of a risk- and cost-benefit ratio. Therefore, evaluation of the efficacy of PCWP monitoring vs. However, pulmonary artery (PA) catheterization involves more risk and cost than monitoring central venous pressures (CVP).
