ABSTRACT

BACKGROUND: Various inotropic agents/vasopressors combinations are used in patients of cardiogenic shock. We performed this study to observe hemodynamic effects of various inotrope/vasopressor combinations in patients with NSTEMI cardiogenic shock (CS) at tertiary cardiac centre METHODS AND MATERIALS: Of 3832 NSTEMI, we studied 59 consecutive such patients with CS who hadn't undergone revascularization in the first 24 h in a prospective, open label, observational study. Group 1 comprised of background Dopamine with Noradrenaline titration(N = 38), Group 2 had background Dobutamine and Noradrenaline titration(N = 15) and Group 3 comprised of triple combination of Dopamine, Noradrenaline & Adrenaline(N = 6). RESULTS: The mean change in hemodynamic parameters between these groups from baseline to 24 h showed no statistical difference. Cardiac output(CO), mean arterial pressure(MAP), central venous pressure(CVP) and cardiac power output(CPO) in group 2 were favorable at 6 and 24 h compared to baseline but mean change was insignificant as compared to others. In group 3, the increase in MAP was significant. IABP use did not change CO, CPO or SVR in any group except lower dosages of Dobutamine (49%) in IABP group. Lower in-hospital mortality in group 2 compared to others (P = 0.004) may be reflective of sicker patients in group 1 and 3. CONCLUSION: The mean changes in hemodynamic parameters were not significant between all groups. All regimes of inotropes when selected as per clinical indication in CS with ACS resulted in similar hemodynamic effects. The mortality difference may not truly be reflective of regimes rather reflect sicker patients in the higher mortality group.

ABSTRACT

Subclavian artery branching patterns have been studied in cadaveric series and frequencies of the many variations have been documented. However, such variations have been seldom noticed antemortem. Here, we present the case of a very rare type of bilaterally different branching pattern of the subclavian artery.
