Insights

Preoperative intraaortic balloon pump support in urgent coronary artery bypass grafting for acute coronary syndrome did not improve outcomes. This high-risk intervention showed no significant reduction in mortality or major adverse events after propensity-score matching.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Vascular Interventions

Background:

  • Urgent or emergency coronary artery bypass grafting (CABG) for acute coronary syndrome (ACS) carries significant risks.
  • Intraaortic balloon pump (IABP) support is a potential intervention for high-risk cardiac surgery patients.

Purpose of the Study:

  • To evaluate the clinical impact of preoperative intraaortic balloon pump (IABP) support in patients undergoing urgent or emergency CABG for ACS.
  • To assess the effect of IABP on postoperative mortality and major adverse cardiovascular and cerebrovascular events (MACCE).

Main Methods:

  • Retrospective review of a single institutional database (April 2010 - December 2016).
  • Analysis of 1066 patients with ACS requiring urgent/emergency CABG.
  • Propensity-score matching was employed to compare outcomes between IABP and control groups.

Main Results:

  • Preoperative IABP use was associated with higher unadjusted mortality (20% vs. control).
  • After propensity-score matching, no significant differences were observed in all-cause mortality (20.0% vs. 18.2%), cardiac mortality (18.2% vs. 14.5%), or MACCE (29.1% vs. 27.3%).
  • Overall hospital mortality was 8.8% in the study cohort.

Conclusions:

  • Preoperative intraaortic balloon pump support does not provide additional clinical benefit for patients undergoing urgent or emergency CABG for acute coronary syndrome.
  • The findings suggest that preoperative IABP is not associated with improved outcomes in this specific high-risk patient population.

ATP Driven Pumps III: V-type Pumps

V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of a few specialized eukaryotic cells, and some prokaryotes. They are also known as the V1Vo-ATPase, that couple ATP hydrolysis to transport protons against a concentration gradient.
The peripheral or cytosolic V1 domain with eight subunits is involved in ATP hydrolysis. The integral or transmembrane V0 domain containing at least five subunits...

ATP Driven Pumps II: P-type Pumps

The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from I to V.
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...

Pumped Concrete01:13

Pumped Concrete

Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

Refrigerators and Heat Pumps01:07

Refrigerators and Heat Pumps

Refrigerators or heat pumps are heat engines operating in a reverse direction. For a refrigerator, the focus is on removing heat from a specific area, whereas, for a heat pump, the focus is on dumping heat into one particular area. A refrigerator (or heat pump) absorbs heat Qc from the cold reservoir at Kelvin temperature Tc and discards heat Qh to the hot reservoir at Kelvin temperature Th, while work W is done on the engine’s working substance.
A household refrigerator removes heat from...

Coronary Circulation01:21

Coronary Circulation

The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

ATP Driven Pumps I: An Overview01:27

ATP Driven Pumps I: An Overview

ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and...
