Comparative Effects of Volume Loading on Pulmonary Venous Flow in Dogs with Normal Heart and with Myocardial Ischemia

et al. 1997

The influences of cardiac loading conditions and left ventricular performance on pulmonary venous flow are poorly understood. The authors studied the effects of volume loading on the pattern of pulmonary venous flow in normal and ischemic hearts. Thirteen anesthetized dogs were equipped with a transit-time ultrasonic flow probe around the left upper pulmonary vein. In 6 of the dogs, the left anterior descending artery was ligated to induce myocardial ischemia. The remaining 7 dogs had normal hearts. Heart rate was fixed at 110 beats/minute by right atrial pacing. Dextran was infused from the femoral vein until mean left atrial pressure increased 3 mm Hg above the baseline value in both groups. In normal heart, systolic pulmonary venous flow volume (SI) increased significantly, but early diastolic flow volume (DI) did not show a significant change during volume loading. The ratio of SI/DI increased significantly (1.12 +/- 0.34 vs 2.11 +/- 0.49, P < 0.05). After ligation of the left anterior descending artery, the SI and DI decreased significantly. The ratio of SI/DI did not show a significant change (0.88 +/- 0.32 vs 0.87 +/- 0.30, ns). In dogs with myocardial ischemia, volume loading caused increases in the SI and DI. However, no significant change was observed in the ratio of SI/DI (0.87 +/- 0.30 vs 0.97 +/- 0.36, ns). These findings demonstrate that left ventricular performance influences the alteration in pulmonary venous flow pattern that is caused by systemic volume loading.

Study of Nailfold Capillaries in Hypertriglyceridemia (Types III and IV Hyperlipoproteinemia)

SUMMARYReflected light nailfold capillaroscopy was used to discover micro-angiopathy in atherosclerotic patients with hypertriglyceridemia (types III and IV hyperlipoproteinemia). In comparison with healthy normolipemic controls, 51 of a series of 64 patients were found to have beds of dilated, congested, elongated, and tortuous capillary venular limbs and loops; and 29 of these with capillary abnormalities were found to have either fresh or old hemorrhages. Serial studies revealed that capillary hemorrhages tended to subside shortly after the hyperlipoproteinemia was controlled by a low carbohydrate diet, while the morphologic abnormalities showed little or no change for 8 to 21 months.

The Circulator Boot is a new end-diastolic pneumatic leg compression device. This report describes its effect on 6 normal young people, 8 ambulatory patients with mild peripheral arterial disease, and 21 consecutive patients (of whom 18 were hospitalized) with severe peripheral arterial disease in 25 legs. The courses of 4 patients are discussed in detail. Significant beneficial effects were documented by subcutaneous PO2 levels, pulse volume measurements, ankle blood pressure measurements, and Doppler ultrasound tracings. Twenty-two of the 25 severe legs benefitted clinically from therapy. Immediate therapeutic effects from the boot are attributed to decreases in venous pressure, interstitial fluid pressure, vasoconstriction, and viscosity, and to increases in cardiac output, pulse pressure, and fibrinolysis in the treated leg. The long-term beneficial effects of boot therapy may be related to improved collateral flow and to the rechanneling of obstructed vessels.
