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

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.

[Indications for permanent electrosystolic pacing in arrhythmia revealed or aggravated by treatment].

The authors report 25 cases of patients, average age 67 years with severe coronary or valvular heart disease, with conduction disorders. The conduction disorder occurred alone in 8 cases and was associated with a disorder of excitability in 17 cases. It was either obvious, as in 14 cases, or latent, as in 11 cases, and precipitated by various forms of treatment, the disadvantage of which was the negative dromotrope effect. This treatment was prescribed for permanent resting angina (amiodarone and prenylamine), heart failure (digitoxin) or excitability disorder (beta-blockaders or procainamide). 11 patients had one or several fainting attacks. Permanent electro-systolic pacing with stimulation on demand, is necessary in all patients to palliate the consequences of treatment. In 11 cases out of 25, prior temporary pacing permitted the authors to assess the efficacy of treatment. The high post-operative mortality (40%) is not due to the apparatus but depends on the severity of the coronary heart disease or heart failure in these patients, In 60% of cases, the result of stimulation was excellent and was maintained permanently.

[Cardiac causes of acute ischemia of lower limbs].

Acute ischemias of the legs of cardiac origin are almost always due to leg embolus caused by fragmentation of an endoauricular or left venticular thrombosis. The two main causes are easily recognized: mitral narrowing and ventricular aneurysm are seldom accompanied by seeding, because a prophylactic treatment with anti-vitamin K is started as soon as the diagnosis is made. Use of prosthetic valves, despite constant improvement in their manufacture and systematic administration of anticoagulant drugs, are always complicated by embolisms (4 to 7% of cases at present). On the other hand, two causes of leg embolisms should be carefully sought since they give rise to revealing seedings. Non-obstructive cardiomyopathy gives a picture of primitive cardiac insufficiency developing progressively. Paroxysmal supraventricular rhythm disorders may be completely overlooked, and only an electrocardiogram continued during 24 hours allows their detection. Embolisms which do not involve the legs, are secondary. Seeding of a chalky fragment from a stenotic aortic valve is very rare. On the other hand, embolisms of anauricular fragment of myxoma and especially membranous embolisms during infectious endocarditis, are not so rare.
