Heart Failure

Forfia PR, Watkins SP, Rame JE, et al. Relationship between B-type natriuretic peptides and pulmonary capillary wedge pressure in the intensive care unit. J Am Coll Cardiol. 2005; 45:1667-71. BNP and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are highly correlated with left ventricular (LV) filling pressures in patients with depressed LV systolic function but less is known about their utility in ICU patients. This study found peptide levels were approximately four-fold greater in patients with impaired (estimated glomerular filtration rate [eGFR] <60 ml/min) versus normal (eGFR >60 ml/min) renal function, despite similar PCWP, cardiac index, and LV ejection fraction.

Mebazaa A, Gheorghiade M, Pina IL, et al. Practical recommendations for prehospital and early in-hospital management of patients presenting with acute heart failure syndromes. Crit Care Med 2008; 36[Suppl]:S129-139. Intensivists are often involved in the early management of heart failure patients but there are few randomized studies to guide management in this setting. These guidelines are derived primarily from expert opinion and provide recommendations on the use nitrates, inotropes, pressors, diuretics, and fluids based on various clinical scenarios.

Binanay C, Califf RM, Hasselblad V, et al. Evaluation study of congestive heart failure and pulmonary artery catheterization effectiveness: the ESCAPE trial. JAMA 2005; 294:1625-33. This RCT of 433 patients with acute decompensated CHF (but not shock) found no difference in resolution of symptoms, mortality, or days alive and out of the hospital at 6 months. There was a higher incidence of adverse events in the group randomized to PAC. This data suggests the use of PAC is not indicated for the routine management of decompensated CHF.

Cardiogenic shock

DeBacker D, Biston P, Devriendt J, et al. SOAP II Investigators. Comparison of dopamine and norepinephrine in the treatment of shock. N Engl J Med. 2010;362:779-89. Large multicenter RCT of 1679 patients with shock of any etiology, demonstrated equal mortality and significantly fewer arrhythmias with norepinephrine as first line vasopressor. Subgroup of those with cardiogenic shock had higher mortality with dopamine. Concerns raised have included heterogeneity of shock physiologies included, restricted fluid resuscitation protocol, and open label use of norepinephrine after conservative max doses of study drug. However, this study adds valuable evidence to our currently limited understanding of comparative merits of pressors.

Thiele H, Zeymer U, Neumann FJ, et al. IABP-SHOCK II Trial Investigators. Intraaortic balloon support for myocardial infarction with cardiogenic shock. N Engl J Med. 2012; 367 :1287-96. Randomized study of 600 patients with cardiogenic shock complicating acute myocardial infarction found no difference in all-cause 30-day mortality with use of intraaortic balloon counterpulsation (IABP) compared to no IABP. The IABP group had less multiorgan dysfunction at days 2 and 3 but there was no difference by day 4.
