A comparison of one-year treatment utilization for shoulder osteoarthritis patients initiating care with non-orthopaedic physicians and orthopaedic specialists.

BACKGROUND: In this paper we investigate patients seeking care for a new diagnosis of shoulder osteoarthritis (OA) and the association between a patient's initial physician specialty choice and one-year surgical and conservative treatment utilization. METHODS: Using retrospective data from a single large regional healthcare system, we identified 572 individuals with a new diagnosis of shoulder OA and identified the specialty of the physician which was listed as the performing physician on the index shoulder visit. We assessed treatment utilization in the year following the index shoulder visit for patients initiating care with a non-orthopaedic physician (NOP) or an orthopaedic specialist (OS). Descriptive statistics were calculated for each group and subsequent one-year surgical and conservative treatment utilization was compared between groups. RESULTS: Of the 572 patients included in the study, 474 (83%) received care from an OS on the date of their index shoulder visit, while 98 (17%) received care from a NOP. There were no differences in baseline patient age, gender, BMI or pain scores between groups. OS patients reported longer symptom duration and a higher rate of comorbid shoulder diagnoses. Patients initiating care with an OS on average received their first treatment much faster than patients initiating care with NOP (16.3 days [95% CI, 12.8, 19.7] vs. 32.3 days [95% CI, 21.0, 43.6], Z = 4.9, p < 0.01). Additionally, patients initiating care with an OS had higher odds of receiving surgery (OR = 2.65, 95% CI: 1.42, 4.95) in the year following their index shoulder visit. CONCLUSIONS: Patients initiating care with an OS received treatment much faster and were treated with more invasive services over the year following their index shoulder visit. Future work should compare patient-reported outcomes across patient groups to assess whether more expensive and invasive treatments yield better outcomes for patients with shoulder OA.

Outcome of Patients With Systolic Heart Failure Who Underwent Sympathectomy for Ventricular Arrhythmia.

Cardiac sympathetic denervation (CSD) is a surgical procedure increasingly used for managing ventricular arrhythmia refractory to conventional medical therapy. Long-term outcomes of CSD in patients with systolic heart failure has not been well studied. This observational study aimed to evaluate the medical co-morbidities and outcomes of patients with systolic heart failure who underwent CSD performed as treatment for ventricular arrhythmia refractory to conventional therapy. A retrospective analysis in adult patients with ventricular arrhythmia and systolic heart failure who underwent unilateral or bilateral CSD at a single center was performed. Unadjusted Kaplan-Meier survival curves were constructed to evaluate survival after CSD. Between June 1, 2011 and March 31, 2021, 32 adult patients (age 62 ± 11.6 years, 88% male, left ventricular ejection fraction 22% ± 8.2%) with systolic heart failure underwent unilateral left (n = 4), unilateral right (n = 1), or bilateral CSD (n = 27). Mean survival after CSD was 613 ± 745 days, and the mean time from CSD to death was 291 ± 447 days. The cumulative probability of survival 1 year after CSD was 61.4%. In this single-center observational study, CSD performed for refractory ventricular arrhythmia showed favorable survival in patients with systolic heart failure. In conclusion, this study lays the groundwork for a more in-depth analysis of the potential survival benefits of CSD in this patient group.

Transthyretin Cardiac Amyloidosis Disguised as Light Chain Amyloidosis or Multiple Myeloma?

We describe 2 challenging cases of cardiac transthyretin amyloidosis initially treated as cardiac amyloidosis light chain in the setting of active myeloma. Endomyocardial biopsy with mass spectrometry was essential to confirm the appropriate diagnosis to direct the treatment.

Concomitant coronary microvascular dysfunction and spontaneous coronary artery dissection resulting in ST-segment elevation myocardial infarction.

We report a patient with angina and no flow-limiting epicardial coronary artery disease who presented with recurrent spontaneous coronary artery dissection resulting in an acute ST-elevation myocardial infarction and evidence of coronary microvascular dysfunction on coronary angiography. We review each condition's pathophysiology and provide a review of the literature for reported associations between these disease processes. .

Circulating Biomarkers in Hypertrophic Cardiomyopathy.

Hypertrophic cardiomyopathy is the most common genetic heart disease. Biomarkers, molecules measurable in the blood, could inform the clinician by aiding in diagnosis, directing treatment, and predicting outcomes. We present an updated review of circulating biomarkers in hypertrophic cardiomyopathy representing key pathologic processes including wall stretch, myocardial necrosis, fibrosis, inflammation, hypertrophy, and endothelial dysfunction, in addition to their clinical significance.

Delayed presentation of pericardial tamponade following blunt chest trauma.

We present a case of delayed-onset pericardial tamponade nine weeks after a blunt chest trauma. The patient is a 77-year-old man who presented with shortness of breath nine weeks after fracturing his sternum in a head-on motor vehicle collision. CT and echocardiography revealed a massive pericardial effusion prompting pericardiocentesis. Eight hundred millilitres (mL) of fluid were drained, which rapidly improved his symptoms. This is the longest reported interval between the development of tamponade and a blunt chest trauma. Our case illustrates the importance of maintaining a clinical suspicion for effusion and tamponade even weeks after non-penetrating chest wall injuries.

Extremely Heavy Lifting Associated With Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection (SCAD) is a separation of the intimal wall by intramural hemorrhage and has been classically associated with young women. We report a case of a healthy 58-year-old man who presented with chest pain that arose shortly after lifting machinery that was known to weigh 200-250 pounds. He was admitted with a non-ST elevation myocardial infarction and was later found to have non-atherosclerotic SCAD. No underlying cause was identified, and the patient was managed medically. This case illustrates that physicians should maintain an index of suspicion for SCAD as a cause of acute coronary syndrome even in male patients without diseases associated with the condition, especially when heavy lifting is reported.

Acute coronary syndrome as the first presentation of antiphospholipid antibody syndrome.

We describe a case of a 42-year-old man who presented with anginal chest pain. He had objective evidence of ongoing cardiac injury. After initial treatment for coronary arterial disease, cardiac catheterisation revealed diffuse coronary arterial thrombosis with embolisation. Follow-up testing implicated new-onset antiphospholipid antibody syndrome as the aetiology.

Massive Tension Hemothorax After Pacemaker Implantation.

A case of an 85-year-old male on apixaban and clopidogrel undergoing pacemaker implantation is described. After procedure he developed unilateral tension hemothorax and required emergent drainage and exploratory thoracotomy. No vascular, cardiac, or pulmonary source was identified. After multidisciplinary discussions, it was speculated that spontaneous intercostal vessel rupture due to forceful coughing and elevated blood pressure during the procedure was the most likely cause of bleeding.

Promoting Cardiac Rehabilitation in Acute Coronary Syndrome Patients: Quality Initiative Based on Education, Automated Referral, and Multidisciplinary Rounds.

Cardiac rehabilitation is a class 1 recommendation for acute coronary syndrome (ACS) patients according to the American College of Cardiology/American Heart Association. However, only 1 in 5 ACS patients are referred for cardiac rehabilitation nationally, and even fewer at our institution. We sought to improve the number of referrals to cardiac rehabilitation for post-ACS patients admitted to our inpatient cardiology service, and ultimately their participation in the program. We designed a quality improvement initiative that included education of patients and house staff, automated referral order, and participation of cardiac rehabilitation staff members on multidisciplinary rounds. We compared the number of patients who received a referral to cardiac rehabilitation, had the first appointment scheduled before hospital discharge, and attended the program before and after our intervention. Six months after initiation of the project, the proportion of ACS patients referred to cardiac rehabilitation before hospital discharge increased from 10% to 43% (P < 0.001). The mean number of patients with a cardiac rehabilitation appointment scheduled before discharge was 2 before and 5 after the intervention (P < 0.001), and the mean number of patients who attended their scheduled appointment was 1 before and 3 after the intervention (P = 0.001). Run charts demonstrated that the number of referrals and the number of scheduled appointments remained above the median following the intervention. In conclusion, an initiative that included education, automated referrals, and direct one-on-one contact with cardiac rehabilitation staff before discharge increased the number of cardiac rehabilitation referrals, and appointments scheduled and attended in post-ACS patients.
