Diastolic Dysfunction, Cardiovascular Aging, and the Anesthesiologist

Diastolic dysfunction, cardiovascular aging, and the anesthesiologist.

As the number of persons aged 65 years and older continues to increase, the anesthesiologist will more frequently encounter this demographic. Cardiovascular changes that occur in this patient population present difficult anesthetic challenges and place these patients at high risk of perioperative morbidity and mortality. The anesthesiologist should be knowledgeable about these age-related cardi...

Characterization of Aging-Associated Cardiac Diastolic Dysfunction

AIMS Diastolic dysfunction is common in geriatric heart failure. A reliable parameter to predict myocardium stiffness and relaxation under similar end-diastolic pressure is being developed. We propose a material and mathematical model for calculating myocardium stiffness based on the concept of linear correlation between [Formula: see text] and wedge pressure. METHODS AND RESULTS We enrolled ...

Mitophagy: New Insight into the Cardiovascular Aging  

Left ventricular diastolic dysfunction of the cardiac surgery patient; a point of view for the cardiac surgeon and cardio-anesthesiologist

BACKGROUND Left ventricular diastolic dysfunction (DD) is defined as the inability of the ventricle to fill to a normal end-diastolic volume, both during exercise as well as at rest, while left atrial pressure does not exceed 12 mm Hg. We examined the concept of left ventricular diastolic dysfunction in a cardiac surgery setting. MATERIALS AND METHODS Literature review was carried out in orde...

The aging anesthesiologist: a narrative review and suggested strategies

PURPOSE To address an aging anesthesia workforce, we review the relevant changes and implications associated with age in order to stimulate discussion at the individual, local, and national levels regarding appropriate changes in practice aimed at protecting patient safety. PRINCIPAL FINDINGS In a 2013 survey of Canadian Anesthesiologists, 22% were aged 55-64 yr, 7% were aged 65-74 yr, and 3%...
