The findings suggest that patients with advanced liver disease should routinely undergo assessment for low cardiac reserve
, Anoop N.
The findings also add to the concerns about using nonselective beta-blocker drugs in patients with cirrhosis because of the potential of these drugs to further blunt increases in cardiac output; they also suggest that noninvasive measurement of cardiac reserve
could identify patients with low cardiac reserve
who could benefit from closer monitoring and new approaches to treatment, he suggested.
This sympathoadrenal response may be well tolerated in ASA 1 and II patients, but may cause myocardial instability in patients with limited cardiac reserve
due to any reason.
Especially during and immediately after cardiac surgery, the CO change in time may be more interesting than its absolute value, since the patients usually suffer from cardiovascular comorbidity and limited cardiac reserve
With agreement with previous studies we observed minimum heart rate changes after spinal block with small dose of local anesthetic, that this finding is very important in patients with low ejection fraction who had lower cardiac reserve
Albeit, in symptomatic multivessel disease with concomitant limited cardiac reserve
, conventional cardiopulmonary bypass surgery (ONCAB) is considered as the optimal approach, it has been speculated that extracorporeal circulation (CPB) in this surgical approach could exacerbate myocardial damage in patients with compromised left ventricle .
Dupont notes that a patient with carotid artery narrowing is also likely to have coronary artery disease and reduced cardiac reserve
