Identification of acute ST-elevation myocardial infarction via remote implantable loop recorder monitor.

The indications for the use of implantable loop recorders include the evaluation of unexplained palpitations and syncope, embolic stroke of undetermined source, dizziness and lightheadedness presumed to be due to arrhythmogenic etiology, and for atrial fibrillation to guide antiarrhythmic drug therapy or catheter ablation efficacy. Long-term monitoring is especially beneficial if symptoms occur sporadically or are asymptomatic in nature. This is the first case to our knowledge of an acute ST-elevation myocardial infarction which was identified from remote monitoring of an implantable loop recorder through a device clinic.

COVID-19 Cardiovascular Connection: A Review of Cardiac Manifestations in COVID-19 Infection and Treatment Modalities.

The coronavirus pandemic has crippled healthcare system since its outbreak in 2020, and has led to over 2.6 million deaths worldwide. Clinical manifestations of COVID-19 range from asymptomatic carrier to severe pneumonia, to life-threatening acute respiratory distress syndrome (ARDS). The early efforts of the pandemic surrounded treating the pulmonary component of COVID-19, however, there has been robust data surrounding the cardiac complications associated with the virus. This is suspected to be from a marked inflammatory response as well as direct viral injury. Arrhythmias, acute myocardial injury, myocarditis, cardiomyopathy, thrombosis, and myocardial fibrosis are some of the observed cardiac complications. There have been high morbidity and mortality rates in those affected by cardiac conditions associated with COVID-19. Additionally, there have been documented cases of patients presenting with typical cardiac symptoms who are subsequently discovered to have COVID-19 infection. In those who test positive for COVID-19, clinical awareness of the significant cardiac components of the virus is pertinent to prevent morbidity and mortality. Unfortunately, treatment and preventative measures developed for COVID-19 have been shown to be also be associated with cardiac complications. This is a comprehensive review of the cardiac complications and manifestations of COVID-19 infection in addition to those associated with both treatment and vaccination.

SGLT2 inhibitors in hypertension: Role beyond diabetes and heart failure.

Type 2 Diabetes Mellitus (T2DM) is a pandemic that affects millions of patients worldwide. Diabetes affects multiple organ systems leading to comorbidities including hypertension. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) recently have been approved for the treatment of T2DM and heart failure with reduced and preserved ejection fraction. Retrospective analyses of clinical trials have noted SGLT2 inhibitors to have a promising effect on blood pressure. Moreover, the observed blood pressure reduction is not just an acute effect of treatment initiation but has been shown to have a long-term impact on both systolic and diastolic blood pressure. The mechanism of action leading to the blood pressure reduction is still unclear; however, proposed mechanisms are related to the natriuretic effect, modification of the renin-angiotensin-aldosterone system, and/or the reduction in the sympathetic nervous system, SGLT2i should be considered as second-line medication in those patients with diabetes or heart disease and concomitant hypertension. This article reviews the pharmacology, side effect profile, and clinical trials surrounding the use of SGLT2i for the treatment of hypertension.

Vericiguat: A Novel Soluble Guanylate Cyclase Stimulator for Use in Patients With Heart Failure.

Heart failure (HF) affects 6.2 million Americans and is increasing annually in its frequency. Treatment of HF has been at the forefront of medical advancements due to the financial burden on our health care system. As such, changes to the guidelines regarding standard of care have been evolving over the last decade with the recent additions of sacubitril-valsartan and sodium glucose co-transporter-2 inhibitors to standard of care in the treatment of HF. Despite the aforementioned expansions in treatment options, HF continues to have a significant impact on the American health care system. Most recently, a novel drug vericiguat that targets an unprecedented pathway for the treatment of HF was Food and Drug Administration approved for the management of patients with HF with a reduced ejection fraction with a recent hospitalization or need for outpatient intravenous diuretics. In clinical trials, vericiguat was associated with a reduction in death from cardiovascular causes and first hospitalization in comparison to placebo. The aim of this review is to provide a comprehensive literature analysis of the various trials surrounding the approval of vericiguat and to both inform and synthesize the data surrounding the clinical use of vericiguat. The introduction of Vericiguat should be considered as a treatment option in patients to decrease the mortality/morbidity of HF with reduced ejection fraction and to increase the quality of life.

Family Engagement in the Adult Cardiac Intensive Care Unit: A Survey of Family Engagement Practices in the Cardiac Critical Care Trials Network.

BACKGROUND: Cardiovascular and critical care professional societies recommend incorporating family engagement practices into routine clinical care. However, little is known about current family engagement practices in contemporary cardiac intensive care units (CICUs). METHODS: We implemented a validated 12-item family engagement practice survey among site investigators participating in the Critical Care Cardiology Trials Network, a collaborative network of CICUs in North America. The survey includes 9 items assessing specific engagement practices, 1 item about other family-centered care practices, and 2 open-ended questions on strategies and barriers concerning family engagement practice. We developed an engagement practice score by assigning 1 point for each family engagement practice partially or fully adopted at each site (max score 9). We assessed for relationships between the engagement practice score and CICU demographics. RESULTS: All sites (N=39; 100%) completed the survey. The most common family engagement practices were open visitation (95%), information and support to families (85%), structured care conferences (n=82%), and family participation in rounds (77%). The median engagement practice score was 5 (interquartile range, 4). There were no differences in engagement practice scores by geographic region or CICU type. The most commonly used strategies to promote family engagement were family presence during rounds (41%), communication (28%), and family meetings (28%). The most common barriers to family engagement were COVID-related visitation policies (38%) and resource limitations (13%). CONCLUSIONS: Family engagement practices are routinely performed in many CICUs; however, considerable variability exists. There is a need for strategies to address the variability of family engagement practices in CICUs.

Utilization of sacubitril-valsartan for right ventricular failure in a patient with arrhythmogenic right ventricular cardiomyopathy.

Arrhythmogenic right ventricular (RV) cardiomyopathy is an autosomal dominant inherited cardiomyopathy that is characterized by an increased risk of ventricular arrhythmias, sudden cardiac death and, less commonly, heart failure. The authors present the case of a 36-year-old woman with familial lamin cardiomyopathy with positive LMNA mutation and genetic testing revealing LMNA and TMEM43 mutations consistent with arrhythmogenic RV cardiomyopathy. The patient presented with clinical signs of RV failure. Transthoracic echocardiogram showed newly reduced RV function in the absence of left ventricular involvement. Cardiac MRI demonstrated diffuse late gadolinium enhancement of the mid-level and apical RV anterior free wall. Diuretics were started, and sacubitril-valsartan was added when the patient's symptoms persisted. Diuretics were then discontinued, and sacubitril-valsartan was the primary therapy. This is the first reported case of symptomatic and imaging-proven RV recovery in a patient with symptomatic RV failure in the setting of arrhythmogenic RV cardiomyopathy treated with sacubitril-valsartan.

The authors present the case of a 36-year-old woman who was found to have arrhythmogenic right ventricular cardiomyopathy, a rare inherited cardiomyopathy. This condition is caused by various mutations that lead to cardiac muscle cells being replaced with fibrofatty tissue and manifests as heart arrhythmias, sudden cardiac death or heart failure. The patient presented with symptoms of right heart failure. Imaging found a new reduction in right ventricular function, confirming the diagnosis of right heart failure. The patient was treated initially with diuretics. However, her symptoms persisted despite treatment and sacubitril­valsartan was started, after which she symptomatically improved. Repeat imaging showed improvement in right ventricular function with sacubitril­valsartan therapy.

The Hype Surrounding Patent Foramen Ovale Closure and Cryptogenic Stroke: A Walk Through History.

Cryptogenic stroke (CS) represents one-third of all ischaemic strokes. Studies have shown approximately that half of patients with CS have concomitant patent foramen ovale (PFO), with clear data supporting paradoxical embolization as an aetiology of CS. This article is the first of a multi-part review and will detail the history of PFO closure and the clinical trials that have evaluated the efficacy of PFO device closure. Data favour PFO closure in CS for reducing stroke in appropriate patients and should be considered as a treatment modality.

Inpatient palliative care encounter and 30-day readmission among hospitalizations for heart failure.

Aim: To determine the association between inpatient palliative care encounter (PCE) and 30-day rehospitalization. Materials & methods: The Nationwide Readmission Database was used in a cross-sectional design study. Comorbidities and a palliative care encounter (PCE; V66.7) were defined using ICD-9 codes. Results: Overall, 21.28% of 3,534,480 index hospitalizations were readmitted. PCE occurred in 1.66% of index hospitalizations and was associated with a lower odds of 30-day rehospitalization (adjusted odds ratio, 0.38; 95% CI: 0.35-0.40). This association remained significant when assessed by discharge destination. Conclusion: PCE was associated with a lower relative odds of 30-day rehospitalization. A 73% decrease in the relative odds of 30-day rehospitalization among discharges to a facility, 64% for home with home health, and 22% for discharges to home.

Finerenone: A New Era for Mineralocorticoid Receptor Antagonism and Cardiorenal Protection.

The renin-angiotensin-aldosterone system is a neurohormonal system responsible for maintaining homeostasis of fluid regulation, sodium balance, and blood pressure. The complexity of this pathway enables it to be a common target for blood pressure and volume-regulating medications. The mineralocorticoid receptor is one of these targets, and is found not only in the kidney, but also tissues making up the heart, blood vessels, and adipose. Mineralocorticoid receptor antagonists have been shown to slow progression of chronic kidney disease, treat refractory hypertension and primary aldosteronism, and improve morbidity and mortality in management of heart failure with reduced ejection fraction. The more well-studied medications were derived from steroid-based compounds, and thus come with a distinct side-effect profile. To avoid these adverse effects, developing a mineralocorticoid receptor antagonist (MRA) from a non-steroidal base compound has gained much interest. This review will focus on the novel non-steroidal MRA, Finerenone, to describe its unique mechanism of action while summarizing the available clinical trials supporting its use in patients with various etiologies of cardiorenal disease.
