Article Synopsis
- In a study analyzing patients during high-risk percutaneous coronary intervention (HR-PCI), nearly half (49%) experienced loss of pulse pressure (LOPP), defined as a mean pulse pressure below 20 mm Hg for 5 seconds or more.
- Patients with LOPP demonstrated significantly lower baseline systolic and mean arterial blood pressures and a higher heart rate compared to those without LOPP.
- The occurrence of LOPP was linked to a higher incidence of serious complications including major adverse cardiac events, acute kidney injury, and death within 90 days, with low systolic blood pressure and cardiomyopathy identified as strong predictors of LOPP.
Article Synopsis
- Right ventricular dysfunction (RVD) affects 30-40% of patients experiencing acute myocardial infarction and cardiogenic shock, leading to concerns about their survival outcomes when treated with left ventricular mechanical support.
- A study conducted across 80 sites analyzed 361 patients, finding that 28% had RVD, which correlated with lower survival rates to discharge (61.8% vs. 73.4%) and higher instances of severe shock and active CPR during treatment.
- Despite initial lower survival for RVD patients, hemodynamic parameters measured within 24 hours showed no significant differences between those with and without RVD, indicating that early left ventricular support may not immediately affect RV function.

Article Synopsis
- TAVR (transcatheter aortic valve replacement) offers treatment for severely ill patients, but outcomes for those with cardiogenic shock (CS) are not well understood.
- A meta-analysis of five studies showed that 30-day mortality and major vascular complications were significantly higher in patients with CS compared to those without, but there were no significant differences in longer-term outcomes at one year.
- The study suggests that while short-term risks are elevated for TAVR patients with CS, their long-term prognosis may be similar to those without CS; further research is needed to explore the timing and management strategies of TAVR for this group.
