CB1-R Deletion Attenuates the Binge Alcohol Intoxication-Induced Cardiac Dysfunction
(A) Representative P-V loops of alcohol-binged CB1+/+ and CB1-/- mice after gradual preload reduction obtained by vena cava occlusion. Red lines indicate the slope of end-systolic P-V relationship, whereas blue lines show the slope of end-diastolic P-V relationship. (B) Load-independent indices of LV performance (Ees, the dP/dtmax – EDV relation, and PRSW) in control or in alcohol-binged CB1+/+ and CB1-/- mice. Data are expressed as mean ± SEM, n = 5 to 6; *p < 0.05 vs. corresponding control group; #p < 0.05 vs. alcohol-binged CB1+/+ group. Abbreviations as in Figures 1, 2, 5, and 6.
