President Harry Truman signed the National Heart Act in 1948, which resulted in the creation of the National Heart Institute and started federal funds flowing to academic centers to support cardiovascular research. Mayo cardiologist Arlie Barnes’s term as president of the American Heart Association coincided with its transformation from a low-budget professional society into a large voluntary health organization that raised funds from the public to support its programs. World War II research into shock contributed to the development of cardiac catheterization as a clinical diagnostic tool. Mayo’s wartime research program that focused on ways to protect fighter pilots from blackouts due to high gravitational forces led to the invention of technologies to measure blood pressure and blood oxygen content. Physiologist Earl Wood used these tools in Mayo’s cardiac catheterization laboratory, which was established at the institution in 1947. The clinic helped pioneer the emerging field of cardiac catheterization.

Scientific Statement

Cardiac catheterization procedures have rapidly evolved and expanded in scope and techniques over the past few decades. However, although some practices have emerged based on evidence, many traditions have persisted based on beliefs and theoretical concerns. The aim of this review is to highlight common preprocedure, intraprocedure, and postprocedure catheterization laboratory practices where evidence has accumulated over the past few decades to support or discount traditionally held practices.

The Difference

AbstractHypothesis:Emergency Medical Services (EMS) systems have developed protocols for prehospital activation of the cardiac catheterization laboratory for patients with suspected ST-elevation myocardial infarction (STEMI) to decrease first-medical-contact-to-balloon time (FMC2B). The rate of “false positive” prehospital activations is high. In order to decrease this rate and expedite care for patients with true STEMI, the American Heart Association (AHA; Dallas, Texas USA) developed the Mission Lifeline PreAct STEMI algorithm, which was implemented in Los Angeles County (LAC; California USA) in 2015. The hypothesis of this study was that implementation of the PreAct algorithm would increase the positive predictive value (PPV) of prehospital activation.Methods:This is an observational pre-/post-study of the effect of the implementation of the PreAct algorithm for patients with suspected STEMI transported to one of five STEMI Receiving Centers (SRCs) within the LAC Regional System. The primary outcome was the PPV of cardiac catheterization laboratory activation for percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). The secondary outcome was FMC2B.Results:A total of 1,877 patients were analyzed for the primary outcome in the pre-intervention period and 405 patients in the post-intervention period. There was an overall decrease in cardiac catheterization laboratory activations, from 67% in the pre-intervention period to 49% in the post-intervention period (95% CI for the difference, -14% to -22%). The overall rate of cardiac catheterization declined in post-intervention period as compared the pre-intervention period, from 34% to 30% (95% CI, for the difference -7.6% to 0.4%), but actually increased for subjects who had activation (48% versus 58%; 95% CI, 4.6%-15.0%). Implementation of the PreAct algorithm was associated with an increase in the PPV of activation for PCI or CABG from 37.9% to 48.6%. The overall odds ratio (OR) associated with the intervention was 1.4 (95% CI, 1.1-1.8). The effect of the intervention was to decrease variability between medical centers. There was no associated change in average FMC2B.Conclusions:The implementation of the PreAct algorithm in the LAC EMS system was associated with an overall increase in the PPV of cardiac catheterization laboratory activation.

Summary Objectives : This paper introduces a pen-based interface for the graphical reporting of findings in cardiac catheterization. Methods : The user can interactively draw, erase, move, and deform coronary arteries as well as record stenoses on them. The location and degree of each stenosis is represented visually and the doctor can record various treatments such as bypasses and stents on the diagram. In addition, the system automatically extracts semantic information from the graphical representation and stores it in XML format. The system can also generate a table in the format specified by the American Heart Association. Results : Our current implementation is a research prototype and is not yet being used in clinical practice. However, we have already demonstrated it to medical professionals and confirmed the following benefits. Conclusions : This system is useful not only as a tool for efficiently generating reports of findings but also as an effective explanation tool for patients.

Hospital Cardiac Arrest

Background: The characteristics and outcomes of in-hospital cardiac arrest (IHCA) in the cardiac catheterization laboratory (CCL) have not been well-described. We compared the characteristics and outcomes of patients with an IHCA in the CCL versus those in the operating room (OR) and the intensive care unit (ICU). Methods: Within the American Heart Association’s Get With the Guidelines-Resuscitation® registry, we identified patients 18 years of age or older with an IHCA in the CCL, OR, or ICU between 2000 and 2019. We compared rates of survival to discharge for patients in the CCL, OR, and ICU. Additionally, we examined predictors of survival to discharge for patients with IHCA in the CCL. Results: There were 6866, 5181, and 181,832 patients with an IHCA in the CCL, OR, and ICU, respectively. Patients with IHCAs in the CCL were more likely to have a shockable cardiac arrest rhythm as compared with those in the OR and ICU. Overall, 2614 (38.1%) patients with IHCA in the CCL survived to discharge, as compared with 30,833 (16.9%) from the ICU and 2096 (40.5%) from the OR. After adjustment for 27 patient and cardiac arrest factors, patients with IHCA in CCL were more likely to survive to discharge as compared with those with IHCA from the ICU (odds ratio, 1.37 [95% CI: 1.29-1.46], p<0.001). In contrast, they were less likely to survive to discharge as compared with those with IHCA in the OR (odds ratio, 0.81 [95% CI: 0.69-0.94], p=0.006). Predictors of survival to discharge in patients with IHCA in the CCL included white race, pulseless ventricular tachycardia/fibrillation, and IHCA during normal hours and on weekdays, while having myocardial infarction during this or prior hospitalization was associated with less survival to discharge. (Table). Conclusion: IHCA in the CCL is not uncommon and has a lower survival rate as compared with IHCA in other procedural areas such as the OR. The reasons for this difference deserve further study given that response to IHCAs in both settings should be similar.
