Sleep deprivation in interventional cardiology: Implications for patient care and physician-health.

The burden and impact of sleep deprivation on both patient care and on the health of interventional cardiologists is not well understood. Due to the nature of emergent procedures occurring in the cardiac catheterization laboratory, interventionalists are prone to suffer from acute and/or chronic sleep deprivation. Sleep deprivation has been associated with numerous adverse effects, such as impaired performance, cognitive deficits, reduced psychomotor vigilance, and workplace errors and injuries, among many others. Although sleep deprivation has been linked to more errors in trainees, there is paucity of data addressing outcomes in interventional cardiology. The purpose of this overview is to explore the possible impact of sleep deprivation on interventional cardiology in relation to patient care and physician health, and examine potential approaches to this issue.

Covered stent implantation through a single 8-french guide catheter for the management of a distal coronary perforation.

Distal coronary perforation can cause early or late tamponade and is usually treated with fat or coil embolization. An alternative treatment strategy is occlusion of the ostium of the perforated vessel via implantation of a covered stent in the main vessel, which is typically achieved using the ping-pong guide catheter technique. In this technique, a balloon is inflated over one guide catheter to stop pericardial bleeding and a covered stent is delivered through a second guide catheter due to inability to fit both a balloon and a covered stent through a single guide catheter. With development of lower profile rapid exchange covered stents, a single guide catheter can be used to both occlude the target vessel and deliver the covered stent. We describe a case of distal vessel perforation in which a balloon was inflated to stop pericardial bleeding, followed by delivery of a covered stent (Graftmaster, Abbott Vascular) through a single 8-Fr guide catheter. This "block and deliver" technique represents a novel paradigm for treating coronary perforations through a single guide catheter, obviating the need for the ping-pong guide catheter technique. © 2017 Wiley Periodicals, Inc.

Menopausal hormone therapy in women with medical conditions.

Hormone therapy is the most effective treatment for menopause-related symptoms. Current evidence supports its use in young healthy postmenopausal women under the age of 60 years, and within 10 years of menopause, with benefits typically outweighing risks. However, decision making is more complex in the more common clinical scenario of a symptomatic woman with one or more chronic medical conditions that potentially alter the risk-benefit balance of hormone therapy use. In this review, we present the evidence relating to the use of hormone therapy in women with chronic medical conditions such as obesity, hypertension, dyslipidemia, diabetes, venous thromboembolism, and autoimmune diseases. We discuss the differences between oral and transdermal routes of administration of estrogen and the situations when one route might be preferred over another. We also review evidence regarding the effect of different progestogens, when available.

Cardiogenic Shock Management: International Survey of Contemporary Practices.

BACKGROUND: Limited data exist on current cardiogenic shock (CS) management strategies. METHODS: A 48-item open- and closed-ended question survey on the diagnosis and management of CS. RESULTS: A total of 211 respondents (3.2%) completed the survey, including 64% interventional cardiologists, 14% general cardiologists, 11% advanced heart failure cardiologists, 5% intensivists, 3% cardiothoracic surgeons; the remainder were internists, emergency medicine, and other physicians. Nearly half (45%) reported practicing at sites without advanced heart failure support/resources, with neither durable ventricular assist devices nor heart transplant available; 16% practice at sites without on-site cardiac surgery and 6% do not offer 24/7 percutaneous coronary intervention (PCI) coverage. The majority (70%) practice in closed intensive care units with multidisciplinary rounding (73%), cardiologists frequently involved in patient care (89%), and involving cardiology-intensivist co-management (41%). Over half (55%) reported use of CS protocols, 61% reported routine arterial line use, 25% reported routine use of pulmonary artery catheter use to guide management and 9% did not. The preferred vasopressor and/or inotrope was norepinephrine (68%). For coronary angiography and PCI, 53% use transradial access, 72% only revascularize the culprit vessel, and 44% institute mechanical circulatory support (MCS) prior to revascularization. Percutaneous MCS availability was as follows: intra-aortic balloon pump (92%), Impella (78%), peripheral veno-arterial extracorporeal membrane oxygenation (66%), and TandemHeart (28%). Most respondents (58%) do not use a scoring system for risk stratification and most (62%) reported that CS-specific cardiac rehabilitation programs were unavailable at their sites. CONCLUSION: Wide variation exists in the care delivered and/or resources available for patients with CS. Our survey suggests opportunities for standardization of care.

Revascularization in Patients With Spontaneous Coronary Artery Dissection and ST-Segment Elevation Myocardial Infarction.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of myocardial infarction (MI) in younger women, often treated conservatively due to revascularization risks. Revascularization outcomes are largely unknown in SCAD presenting with ST-segment elevation myocardial infarction (STEMI). OBJECTIVES: The purpose of this study was to compare revascularization strategies and outcomes of STEMI-SCAD with STEMI atherosclerosis (STEMI-ATH). METHODS: Consecutive STEMI patients were retrospectively analyzed (2003 to 2017) at 2 regional STEMI programs (Minneapolis Heart Institute and Cedars-Sinai Smidt Heart Institute) with 3-year outcomes. RESULTS: Among 5,208 STEMI patients, SCAD was present in 53 (1%; 93% female). SCAD prevalence was 19% in female STEMI patients age ≤50 years. Compared with STEMI-ATH, STEMI-SCAD patients were younger (age 49 ± 10 years vs. 63 ± 13 years), were more often female (93% vs. 27%), and had more frequent cardiogenic shock (19% vs. 9%); all p ≤ 0.03. In STEMI-SCAD, the culprit artery was more commonly left main (13% vs. 1%) or left anterior descending (47% vs. 38%); both p = 0.003. Acute revascularization was lower in STEMI-SCAD (70% vs. 97%); p < 0.001. In STEMI-SCAD, acute revascularization included percutaneous coronary intervention (PCI), n = 33 (62%), or bypass grafting, n = 4 (8%); PCI success was 91%. Those with revascularization were more likely to have shock, left main culprit, proximal dissection, and initial TIMI (Thrombolysis In Myocardial Infarction) flow grade 0 to 1. The 3-year survival was 98% for STEMI-SCAD versus 84% for STEMI-ATH; p < 0.001. CONCLUSIONS: STEMI-SCAD represents an important STEMI subset, particularly among younger women, characterized by significantly greater frequency of left main or left anterior descending culprit and cardiogenic shock than STEMI-ATH. Primary PCI is successful in most STEMI-SCAD patients, with low 3-year mortality.

Sleep Deprivation in Cardiology: A Multidisciplinary Survey.

BACKGROUND: The burden and impact of sleep deprivation in cardiology has received limited study. METHODS: A multidisciplinary, online survey on sleep health patterns and sleep deprivation involving 44 closed-ended questions was distributed via email list to cardiovascular workers. RESULTS: The survey was circulated among 6683 individuals, of whom 481 (7.2%) completed the survey; 80% of the respondents were men and 70% were interventional cardiologists. Nearly all (91%) had call responsibilities, with 43% doing ≥7 call-nights per month. Sleep disorders were reported in 25%, with 25% using sleep-inducing medications (8.4% at least once per week). The main factors diminishing the quality and/or quantity of sleep were related to work (66%), family and/or personal activities (56%), and staying up late at night writing or studying (48%). Sleep deprivation was associated with difficulty concentrating (58%), lack of motivation (56%), and irritability (68%). Work performance was felt to be hindered by 46% of participants and 8.6% reported an adverse event such as a complication and/ or negative patient outcome likely related to sleep deprivation. Many (56.5%) felt burnout and 85% opined that policies should exist allowing sleep-deprived individuals to go home early post call. CONCLUSIONS: Our survey provides insights into sleep health patterns among cardiovascular workers and potential factors contributing to sleep deprivation. Sleep deprivation may impact performance, with 8.6% of respondents describing sleep-deprivation related adverse events. Further study is required to both identify measures to attenuate the burden and better understand the impact of sleep deprivation on both health-care personnel and patient outcomes.

New Insights Into the Use of the 12-Lead Electrocardiogram for Diagnosing Acute Myocardial Infarction in the Emergency Department.

The 12-lead electrocardiogram (ECG) remains the most immediately accessible and widely used initial diagnostic tool for guiding management in patients with suspected myocardial infarction (MI). Although the development of high-sensitivity cardiac troponin assays has improved the rule-in and rule-out and risk stratification of acute MI without ST elevation, the immediate management of the subset of acute MI with acute coronary occlusion depends on integrating clinical presentation and ECG findings. Careful interpretation of the ECG might yield subtle features suggestive of ischemia that might facilitate more rapid triage of patients with subtle acute coronary occlusion or, conversely, in identification of ST-elevation MI mimics (pseudo ST-elevation MI patterns). Our goal in this review article is to consider recent advances in the use of the ECG to diagnose coronary occlusion MIs, including the application of rules that allow MI to be diagnosed on the basis of atypical ECG manifestations. Such rules include the modified Sgarbossa criteria allowing identification of acute MI in left bundle branch block or ventricular pacing, the 3- and 4-variable formula to differentiate normal ST elevation (formerly called early repolarization) from subtle ECG signs of left anterior descending coronary artery occlusion, the differentiation of ST elevation of left ventricular aneurysm from that of acute anterior MI, and the use of lead aVL in the recognition of inferior MI. Improved use of the ECG is essential to improving the diagnosis and appropriate early management of acute coronary occlusion MIs, which will lead to improved outcomes for patients who present with acute coronary syndrome.

Contemporary Arterial Access in the Cardiac Catheterization Laboratory.

Obtaining femoral and radial arterial access in the cardiac catheterization laboratory using state-of-the-art techniques is essential to optimize outcomes, patient satisfaction, and procedural efficiency. Although transradial access is increasingly used for coronary angiography and percutaneous coronary intervention, femoral access remains necessary for numerous procedures, many requiring large-bore access, including complex high-risk coronary interventions, structural procedures, and procedures involving mechanical circulatory support. For femoral access, contemporary access techniques should combine the use of fluoroscopy, ultrasound, micropuncture needle, femoral angiography, and vascular closure devices, when feasible. For radial access, ultrasound may reveal important anatomic features and expedite access. Despite randomized controlled trials supporting use of routine ultrasound guidance for femoral and/or radial arterial access, ultrasound remains underused in cardiac catheterization laboratories. This article reviews contemporary techniques to achieve optimal arterial access in the cardiac catheterization laboratory.
