Stratifying Deterioration Risk by Acuity at Admission Offers Triage Insights for Coronavirus Disease 2019 Patients.

OBJECTIVES: Triaging patients at admission to determine subsequent deterioration risk can be difficult. This is especially true of coronavirus disease 2019 patients, some of whom experience significant physiologic deterioration due to dysregulated immune response following admission. A well-established acuity measure, the Rothman Index, is evaluated for stratification of patients at admission into high or low risk of subsequent deterioration. DESIGN: Multicenter retrospective study. SETTING: One academic medical center in Connecticut, and three community hospitals in Connecticut and Maryland. PATIENTS: Three thousand four hundred ninety-nine coronavirus disease 2019 and 14,658 noncoronavirus disease 2019 adult patients admitted to a medical service between January 1, 2020, and September 15, 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Performance of the Rothman Index at admission to predict in-hospital mortality or ICU utilization for both general medical and coronavirus disease 2019 populations was evaluated using the area under the curve. Precision and recall for mortality prediction were calculated, high- and low-risk thresholds were determined, and patients meeting threshold criteria were characterized. The Rothman Index at admission has good to excellent discriminatory performance for in-hospital mortality in the coronavirus disease 2019 (area under the curve, 0.81-0.84) and noncoronavirus disease 2019 (area under the curve, 0.90-0.92) populations. We show that for a given admission acuity, the risk of deterioration for coronavirus disease 2019 patients is significantly higher than for noncoronavirus disease 2019 patients. At admission, Rothman Index-based thresholds segregate the majority of patients into either high- or low-risk groups; high-risk groups have mortality rates of 34-45% (coronavirus disease 2019) and 17-25% (noncoronavirus disease 2019), whereas low-risk groups have mortality rates of 2-5% (coronavirus disease 2019) and 0.2-0.4% (noncoronavirus disease 2019). Similarly large differences in ICU utilization are also found. CONCLUSIONS: Acuity level at admission may support rapid and effective risk triage. Notably, in-hospital mortality risk associated with a given acuity at admission is significantly higher for coronavirus disease 2019 patients than for noncoronavirus disease 2019 patients. This insight may help physicians more effectively triage coronavirus disease 2019 patients, guiding level of care decisions and resource allocation.

Prospective chest pain evaluation in the emergency department with use of high-sensitivity C-reactive protein (PROCEED-CRP study).

We evaluated the clinical value of a single measurement of high-sensitivity C-reactive protein (hs- CRP) in patients presenting to the emergency department with chest pain. We screened 408 consecutive patients of whom 292 comprised the final cohort for this study. Hs-CRP measured in the emergency department (ED) in patients presenting with chest pain and admitted for evaluation of acute myocardial infarction was neither sensitive nor specific in predicting acute myocardial infarction, myocardial ischemia on SPECT imaging, need for coronary revascularization, or cardiovascular or all-cause rehospitalization at 30 days. In addition, use of a specific CRP cut off >1 was not associated with an increase in all-cause rehospitalization at 30 days.

Psychosocial and cardiac outcomes of yoga for ICD patients: a randomized clinical control trial.

BACKGROUND: Because as many as 46% of implantable cardioverter defibrillator (ICD) patients experience clinical symptoms of shock anxiety, this randomized controlled study evaluated the efficacy of adapted yoga (vs usual care) in reducing clinical psychosocial risks shown to impact morbidity and mortality in ICD recipients. METHODS: Forty-six participants were randomized to a control group or an 8-week adapted yoga group that followed a standardized protocol with weekly classes and home practice. Medical and psychosocial data were collected at baseline and follow-up, then compared and analyzed. RESULTS: Total shock anxiety decreased for the yoga group and increased for the control group, t(4.43, 36), P < 0.0001, with significant differences between these changes. Similarly, consequential anxiety decreased for the yoga group but increased for the control group t(2.86,36) P = 0.007. Compared to the control, the yoga group had greater overall self-compassion, t(-2.84,37), P = 0.007, and greater mindfulness, t(-2.10,37) P = 0.04, at the end of the study. Exploratory analyses utilizing a linear model (R(2) = 0.98) of observed device-treated ventricular (DTV) events revealed that the expected number of DTV events in the yoga group was significantly lower than in the control group (P < 0.0001). Compared to the control, the yoga group had a 32% lower risk of experiencing device-related firings at end of follow-up. CONCLUSIONS: Our study demonstrated psychosocial benefits from a program of adapted yoga (vs usual care) for ICD recipients. These data support continued research to better understand the role of complementary medicine to address ICD-specific stress in cardiac outcomes.

Natural history of the Sprint Fidelis lead: survival analysis from a large single-center study.

PURPOSE: The purposes of our study were to: (1) determine lead failure rate in a large single-center cohort of Sprint Fidelis 6949 (Fidelis) leads, (2) define the risk of lead failure over time, (3) assess the impact of the Lead Integrity Alert (LIA) on lead failure presentation, and (4) identify independent predictors of Fidelis lead failure. METHODS: All patients who underwent implantation of a Fidelis lead between September 2004 and July 2007 were included. Demographic, clinical, and device characteristics at the time of implant and prior to failure were collected and analyzed. RESULTS: A total of 971 Fidelis leads (706 men, 265 women,mean age 68.4±12.8 years) were implanted. Over a mean follow-up of 46.3 months, there were 69 lead failures(7.1%). The 5-year lead survival rate was 90.3%. The risk of lead failure demonstrated a double-peaked pattern at 34 and 61 months. In multivariate analysis, there were no independent predictors of lead failure. Inappropriate shocks(IS) were the first sign of lead failure in 29 patients (42%).The incidence (32.6% vs. 65.2%, p=0.01) and number ofIS (2.8±7.2 vs. 11.3±18.7, p=0.01) were significantly lower in patients with LIA. CONCLUSIONS: This study presents a single-center experience on the natural history of the Fidelis lead. In our experience, lead survival declines at a lower rate when compared to prior reports. The risk of lead failure demonstrated a double peaked pattern at approximately 3 and 5 years. No identified variable was predictive of lead failure. LIA was effective in reducing the incidence and number of IS.

Long-term outcome of Tako-tsubo cardiomyopathy.

BACKGROUND: Current data suggest an excellent outcome for patients with Tako-tsubo cardiomyopathy (TC). The objectives of this study were to evaluate the long-term outcome and the prognostic implication of thrombolysis in myocardial infarction myocardial perfusion grade (TMPG) in patients with TC. METHODS: Retrospective analysis of all patients diagnosed with TC at our hospital between 2003 and 2008. RESULTS: During the five-year period, we identified 27 patients with TC out of 1374 cases of emergent left heart catheterisation (2%). Mean follow-up was 27 ± 16 months. The majority were Caucasian (81%) female (96%), postmenopausal (96%), with a mean age of 68 ± 14 years. A precipitating stressor event was found in 74% of the patients, 30% being gastrointestinal triggers. Fourteen patients (52%) reached a combined end point of all cause death, cardiogenic shock, sudden cardiac death and rehospitalisation for cardiac reasons. TMPG was abnormal in 37% cases with no correlation with the outcome. CONCLUSIONS: The long-term outcome of patients with TC is worse than previously reported. TMPG does not correlate with the outcome in TC.

ECG findings in acute left main coronary artery thrombosis: a case report and review of the literature.

Acute coronary syndrome due to left main coronary artery (LMCA) thrombosis is a catastrophic event associated with poor prognosis and high in-hospital mortality. Early recognition and emergent revascularization is vital for survival. Unfortunately, the electrocardiographic manifestations of LMCA thrombosis are nonspecific. This report describes the electrocardiogram (ECG) findings in a patient with LMCA thrombosis. A new right bundle branch block (RBBB) pattern, especially when associated with ST elevation in aVR and V1, should raise suspicion of this diagnosis.

Coronary artery aneurysms.

Aneurysmal coronary artery disease is frequently encountered in clinical cardiology practice. Although more commonly associated with atherosclerosis, a variety of other acquired (eg, inflammatory, infectious, iatrogenic) or congenital causes have been identified. Recent research on the pathogenesis of coronary aneurysms has yielded interesting results. Advances in imaging have also provided new insights as to the nature of angiographic coronary aneurysms. Critical assessment of the abnormal flow dynamics and pathophysiology of aneurysms has been performed and there is an improved understanding of the associated complications. We present an extensive review of the recent literature highlighting the major advances in the field.

Papillary fibroelastoma arising from the pulmonary valve associated with pulmonary embolization.

Cardiac papillary fibroelastomas are rare, usuallybenign tumors that can be detected at autopsy, during open-heart surgery, or with echocardiography. They usually arise from the cardiac valves and more commonly are found on the left side of the heart. Embolization of left-sided and tricuspid valve tumors has been well documented. This is the 1st reported case of pulmonary embolization of a papillary fibroelastoma arising from the pulmonary valve.

Giant left atrial thrombus successfully treated with anticoagulation.

A giant left atrial mass (6 cm x 4 cm) was visualised on a transoesophageal echocardiogram in an elderly woman who had a history of nonvalvular atrial fibrillation. The surgical removal of the mass, presumed to be a thrombus, was declined by the patient, and oral anticoagulation with warfarin was initiated. After eight weeks of anticoagulation, a repeat echocardiogram demonstrated complete resolution of the mass, without systemic embolisation.

Late thrombosis of drug-eluting stents after discontinuation of clopidogrel: report of two cases and review of the literature.

Thrombosis of intracoronary stents is a major complication associated with significant morbidity and mortality. Of concern are case reports of late (more than six months from deployment) drug-eluting stent thrombosis temporally associated with discontinuation of antiplatelet therapy and when stent endothelialization was presumed to be complete. In certain patients it appears that vascular healing at the stented segments is incomplete with increased susceptibility to late thrombosis. We report two cases of late stent thrombosis occuring more than one year after stent deployment and within weeks of discontinuation of clopidogrel. A review of the literature is presented to identify clinical and angiographic predictors of increased risk.

Apical aneurysm in a patient with apical hypertrophic cardiomyopathy.

Apical hypertrophic cardiomyopathy (AHC) is a variant of hypertrophic cardiomyopathy (HCM) in which the hypertrophy predominantly involves the left ventricular apex. The typical features of AHC include giant negative T waves in the precordial ECG leads, a spade-like configuration of the left ventricle at end-systole, the absence of an outflow tract pressure gradient, and mild symptoms. We present a patient with AHC, evidence of prior myocardial infarction with aneurysm of the apical region, and myocardial ischemia on radionuclide scanning despite angiographically normal coronary arteries. The characteristic electrocardiographic, echocardiographic, hemodynamic and angiographic findings as well as prognosis and treatment options are discussed.

Intraaortic balloon pump insertion through the subclavian artery. Subclavian artery insertion of IABP.

The intraaortic balloon pump (IABP) is frequently used in the management of cardiac failure in the setting of myocardial infarction or as a bridge for coronary revascularisation surgery. The IABP is usually inserted through the femoral artery. Occasionally severe aorto-iliac occlusive disease prevents the retrograde passage of the balloon, in which case an anterograde route, usually through the ascending aorta is used. We describe four patients in whom an IABP was placed through the subclavian artery by the joint efforts of cardiologists and vascular surgeons.

Coronary stenting is safe and effective in a high-risk octogenarian patient cohort.

BACKGROUND: Octogenarians represent an increasing percentage of patients with coronary heart disease and are an inherently high-risk population. We sought to define the immediate and long-term results of coronary stenting in the "real-world" environment of a community teaching hospital. METHODS: One hundred ninety-seven consecutive patients older then 80 years who underwent 214 coronary stent procedures were studied. Each patient had postprocedural serial cardiac enzymes and ECG's collected, and was followed for a minimum of 12 months after the procedure. Procedural success was defined as less than 20% residual stenosis, TIMI 3 flow, and absence of major complications (death, nonfatal myocardial infarction, emergent coronary artery bypass graft surgery and stroke). Sixty-five percent of patients presented with an acute coronary syndrome and 93% were functionally New York Heart Association (NYHA) Class III or IV. RESULTS: Procedural success was 95%. Death during the index hospitalization occurred in 3% of patients. An additional 4.1% of patients died during follow-up. The target vessel revascularization rate (TVR) during follow up was 8.6%. Multivariate analysis of selected angiographic and clinical variables did not reveal any predictors of major cardiac events. CONCLUSIONS: Despite a high-risk clinical and angiographic profile, coronary stenting can be safely performed in octogenarians with a high procedural success rate, low complication rate, and excellent 12-month outcome.

Circadian variation and outcome of in-hospital cardiopulmonary resuscitation.

OBJECTIVE: Assessment of contemporary in-hospital cardiopulmonary resuscitation outcomes. METHODS: The study was designed as a retrospective, single-institution, registry investigation of all adult patients for whom a cardiopulmonary resuscitation (CPR) was attempted between October 1, 2002 and September 30, 2004. Hospital, patient's, arrest and outcome variables were included based on the "Utstein Style" of reviewing, reporting, and conducting research on in-hospital resuscitation. RESULTS: 202 patients (94 women, age 70 +/- 15 years) received in-hospital CPR during the study period. One hundred-two events were primary respiratory arrests. Overall, 67% (95% CI 59%-72%) of patients were successfully resuscitated and 38% (95% CI 31%-45%) survived to hospital discharge. Of the patients with initial respiratory depression followed by circulatory collapse, 57% (95% CI 47%-66%) were alive at the end of hospitalization, while 20% (95% CI 13.3%-28.8%) of patients with cardiac arrest survived to hospital discharge (OR=5.2, 95% CI=2.8-9.5, P<0.0001). A circadian variation in the occurrence of primary cardiac arrests was noted with a nadir between midnight and 0600 hours. Though there were fewer events during overnight hours, CPR for patients with a primary cardiac arrest occurring at this time was less likely to be successful (OR = 2.5, 95% CI=1.01-6.1, p=0.04). This did not result in a difference in survival to discharge (OR=2.6, 95% CI=0.7-9.4, p=0.14). CONCLUSION: Primary cardiac arrest has a significantly worse in-hospital outcome when compared to an initial respiratory event. The finding of a circadian variation in both the incidence and outcome of in-hospital primary cardiac arrest is intriguing and warrants further study.

Post-infectious pseudoaneurysm after coronary angioplasty using drug eluting stents.

Infections at the site of coronary stents are uncommon, and believed to be the result of either direct stent contamination at the time of delivery, or from transient bacteraemia from the access site. A case of pseudoaneurysm ("mycotic" aneurysm) of the left anterior descending coronary artery, due to infection with Staphylococcus aureus after paclitaxel-eluting stents implantation is presented.
