Systemic Arterial Pulsatility Index Predicts Adverse Outcomes in Cardiogenic Shock

The shock index predicts acute mortality outcomes in stroke.

BACKGROUND Shock index (SI) (ratio between heart rate and systolic blood pressure) has been shown to be associated with poor mortality outcomes in trauma and pneumonia; however it has yet to be examined in stroke. We aimed to examine the relationship between SI and acute outcomes of inpatient, 3-day and 7-day mortality in stroke. Secondly, we aimed to compare SI and systolic blood pressure (SBP...

Cardiogenic shock: current concepts and improving outcomes.

Cardiogenic shock (CS) occurs in 5% to 8% of patients hospitalized with ST-elevation myocardial infarction (STEMI). Recent research has suggested that the peripheral vasculature and neurohormonal and cytokine systems play a role in the pathogenesis and persistence of CS. Early revascularization for CS improves survival substantially. New mechanical approaches to treatment are available, and cli...

Arterial pulsatility as an index of cerebral microangiopathy in diabetes.

BACKGROUND AND PURPOSE This study was designed to evaluate cerebral hemodynamic changes related to diabetes mellitus (DM) with transcranial Doppler ultrasonography (TCD). METHODS We measured the flow velocities and the Gosling pulsatility index (PI) of the middle cerebral artery (MCA), extracranial internal carotid artery (ICA), and basilar artery (BA) in 56 stroke-free, normotensive patients...

Cardiogenic shock.

The syndrome of cardiogenic shock (CS) comprises a constellation of symptoms and signs that define a subset of patients with inadequate tissue perfusion secondary to myocardial dysfunction. Careful attention to and rapid identification of patients at risk for the development of CS and those with impending CS by both hospitalists and subspecialists will help to implement the time-sensitive thera...
