[Contractility and diastolic complicance of the left ventricle in patients with coronary insufficiency without myocardial necrosis]. 1976

C Le Pailleur, and H Lafont, and B Meilhac, and G Fleury, and A Vacheron, and J D Mattéo

The 19 coronary patients studied were found to have a "normalised" rigidity k = dp/(dVP) identical to that of normal subjects, and a lowered instantaneous end-diast-lic compliance (dV/dP)TD. The increase in end-diastolic pressure is due to a small increase in end-diastolic volume, and brings about Starling's phenomenon to compensate for a diminution in contractility. The maximimum speed of shortening of the myocardium (VCFmax) shows up the baseline contractility, and appears to be more sensitive than the mean speed of myocardial shortening (VCF) and the ejection fraction.

UI MeSH Term Description Entries
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009200 Myocardial Contraction Contractile activity of the MYOCARDIUM. Heart Contractility,Inotropism, Cardiac,Cardiac Inotropism,Cardiac Inotropisms,Contractilities, Heart,Contractility, Heart,Contraction, Myocardial,Contractions, Myocardial,Heart Contractilities,Inotropisms, Cardiac,Myocardial Contractions
D009336 Necrosis The death of cells in an organ or tissue due to disease, injury or failure of the blood supply.
D002302 Cardiac Output The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat). Cardiac Outputs,Output, Cardiac,Outputs, Cardiac
D002306 Cardiac Volume The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME. Heart Volume,Cardiac Volumes,Heart Volumes,Volume, Cardiac,Volume, Heart,Volumes, Cardiac,Volumes, Heart
D003187 Compliance Distensibility measure of a chamber such as the lungs (LUNG COMPLIANCE) or bladder. Compliance is expressed as a change in volume per unit change in pressure.
D003327 Coronary Disease An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

D006352 Heart Ventricles The lower right and left chambers of the heart. The right ventricle pumps venous BLOOD into the LUNGS and the left ventricle pumps oxygenated blood into the systemic arterial circulation.
