Background A multidisciplinary approach improves guideline‐directed medical therapy in systolic heart failure (HF), but its efficacy in patients with HF due to cardiac sarcoidosis is unreported. Methods and Results In a retrospective cohort study, we reviewed 848 patients from our institutional cardiac sarcoidosis clinics, identifying those with a cardiac sarcoidosis diagnosis, HF (left ventricular ejection fraction <50%) at index evaluation, and echocardiograms within 90 days and 11 to 36 months. Patients were stratified by participation in a pharmacist‐led medication therapy management (MTM) program for guideline‐directed medical therapy optimization (MTM versus non‐MTM [NMTM]) without randomization. Demographics, left ventricular ejection fraction, guideline‐directed medical therapy (quantified by Kansas City Medical Optimization score), and immunosuppressive therapy were assessed. Primary outcomes included changes in Kansas City Medical Optimization score, left ventricular ejection fraction, and cardiovascular event–free survival (unplanned HF hospitalization, left ventricular assist device /heart transplant, or death). The final cohort included 111 patients (median age, 57 years; 34% women; 64% New York Heart Association class I–II); 43 (39%) were MTM and 68 (61%) were NMTM. Mean Kansas City Medical Optimization score was similar at index evaluation (MTM, 23.2; NMTM, 29.6; P =0.83). At follow‐up (median, 16 months), the Kansas City Medical Optimization score increased significantly in both groups (MTM, 23.2 to 74.8; P <0.001; NMTM, 29.6 to 58.7; P <0.001) but was higher in MTM ( P =0.001). Mean left ventricular ejection fraction trended toward higher values in MTM (44.4% versus 40.0%, P =0.05). The primary clinical outcome occurred in 1 MTM (2.3%) and 16 NMTM (23.5%) patients, with higher risk in NMTM (hazard ratio, 11.97 [95% CI, 1.58–90.54]; P =0.002). Conclusions In this retrospective cohort study, a pharmacist‐led MTM program was associated with favorable guideline‐directed medical therapy optimization and lower risk of adverse cardiovascular outcomes in patients with cardiac sarcoidosis with HF.

Introduction: Cardiac sarcoidosis (CS) often results in systolic heart failure (HF) and responds favorably to guideline directed medical therapy (GDMT). A multidisciplinary team approach to HF care is recommended but few published examples exist in CS patients. Methods: We queried an institutional registry of 599 CS patients (2000-2023) for patients with index LVEF < 50% (within 90 d of index CS evaluation) and follow-up TTE within 11-36 months. In our CS medication therapy management (MTM) program (started 1/8/2019), pharmacists conduct independent visits with CS patients (in person or remote), discuss GDMT tolerance and symptoms, review monitoring laboratory studies, and adjust GDMT (ACEi/ARB/ARNi, beta-blocker, MRA, and/or SGLT2i) via collaborative practice agreement with the CS cardiologists. Patients were classified as MTM (≥1 MTM encounter) or NMTM patients (0 encounters). We compared (1) GDMT, (2) cardiac remodeling, and (3) clinical outcomes (event free survival to first heart failure hospitalization, LVAD, heart transplant, or death). Results: Nineteen percent (113/599) CS patients met inclusion criteria (34% female, 92% white, median age 57 y, 19% definite CS, 58% probable CS, 31% presumed CS), with 44 MTM (median 11.5 encounters, IQR 11) and 69 NMTM patients. Both MTM and NMTM patients were on a median 2 GDMT agents at index evaluation (p=0.21). At follow-up (median 19 mo MTM, 15 mo NMTM, p=0.05), MTM patients were on more GDMT agents than NMTM (median 3.0 vs 2.0, p<0.001), with higher % target dose of ACEi/ARB/ARNi (98% vs 71%, p=0.009), beta-blocker (87% vs 57%, p=0.004), and SGLT2i use (30% vs 9%, p=0.004), but similar MRA use (48% vs 32%, p=0.09). Immunosuppressive therapy was used in 88% patients (89% MTM vs 87% NMTM, p=0.79). Index LVEF was similar (MTM 36%, NMTM 32%, p=0.07). Mean change in LVEF (excluding LVAD/transplant patients) demonstrated a non-significant trend towards improved remodeling in MTM (+8.6%) vs NMTM patients (+5.5%; p=0.39). MTM patients exhibited lower risk of the clinical outcome (1/44 MTM vs 16/69 MTM patients; univariable HR 0.08 [95%CI 0.01 - 0.63], log-rank p=0.016). Conclusions: A pharmacist MTM program for CS patients with HF is associated with improved GDMT uptitration and clinical outcomes, emphasizing the value of collaborative multidisciplinary CS care.

Introduction: Peripheral artery disease impacts 202 million patients worldwide and is commonly diagnosed via ankle-brachial index. PAD is associated with endothelial dysfunction, which is also common to venous thromboembolism formation. Despite the suspected overlap in pathogenesis, few studies exist investigating the association between these pathologies. We investigated whether PAD with low or elevated ABI is an independent risk factor for VTE. Methods: We reviewed medical records of patients ≥18 years old undergoing ABI measurement with or without PAD symptoms from 01/01/1996 to 08/31/2018 and classified patients by ABI: severely low (ABI 0.00-0.39), moderately low (0.40-0.69), mildly low (0.70-0.90), borderline (0.91-0.99), normal (1.00-1.40), and elevated (>1.40). The primary outcome was incident VTE event after ABI measurement, defined as deep vein thrombosis or pulmonary embolism. Multivariable Cox proportional regression was used to calculate hazard ratios (HR) with 95% confidence intervals after adjusting for age, sex, active smoking, cancer or VTE history, thrombophilia, anticoagulation, and revascularization within 14 days of VTE. Results: In 39,384 unique patients (mean age 66.3±14.2 years, median follow-up 34 months), 5,141 VTE events were observed. Increased VTE risk was observed in PAD patients with severely low ABI (HR 1.26, 95%CI [1.02, 1.29]) compared to patients with normal ABI after multivariable regression. Patients with elevated ABI did not demonstrate an increased risk of VTE. Conclusions: Patients with severe PAD are at higher risk for VTE than patients with normal ABI, which may be due to a multifactorial pathophysiology of profound endothelial injury as well as immobility due to claudication. Further exploration of VTE incidence in patients with severe PAD stratified by functional status is warranted to determine the optimal strategy to minimize thromboembolic morbidity and mortality in this population.

Introduction: Pulmonary vein thrombosis (PVT) is often diagnosed incidentally but data on its management and outcomes are sparse. Methods: We queried our institutional health record to identify patients ≥18 years of age diagnosed with PVT. Demographics, medications, risk factors, diagnostics, treatment, and sequelae were collected by manual chart review. Suspected tumor thrombus cases were excluded. Results: Seventy-two patients with PVT were identified (median age 62 years, 50% male). The cohort was mostly white (85%), overweight (BMI 26 kg/m), with frequent comorbidities including hypertension (44%), hyperlipidemia (38%), atrial fibrillation/flutter (29%), and history of venous thromboembolism (21%). The most common PVT risk factors were active malignancy (54%), lobectomy (21%), surgery within 30 days (19%), and extrinsic vein compression (15%). Most PVT were diagnosed by CT (86%) and affected a single vein (86%), mostly commonly the left upper PV (32%). Laboratory studies revealed median platelet count 243 х 10 9 cells/L (n=58) and D-dimer elevated in 6 patients when measured (67%, n=9). About one-third of patients were on therapeutic anticoagulation (37%) at PVT diagnosis. Most patients were started on new anticoagulation (78%, n=56), with unfractionated heparin as the most common initial therapy (68%). Of those anticoagulated, few were treated with a limited duration (20%, n=11, median 54 d, IQR 95) while most received indefinite anticoagulation (80%, n=45), primarily warfarin (45%), apixaban (24%), or enoxaparin (21%). Serial imaging was obtained in 69% (n=50, median 65 d, IQR 116) and demonstrated resolution of PVT in 32 (64%) patients. Common PVT complications noted were as follows: 4 year risk of LA thrombus (26%, 12/16 anticoagulated), mechanical ventilation (13%), pneumonia (9%), and ischemic stroke (9%, 5/6 anticoagulated). Conclusions: PVT is often associated with active malignancy, lobectomy, recent surgery, and extrinsic vein compression. Most PVT resolve on serial imaging. Clinicians should be aware of potential high-risk sequelae including LA thrombus and stroke as well as high anticoagulation failure rates when managing PVT.

Introduction: Cardiac sarcoidosis (CS) results in HFrEF, but its natural history and response to GDMT remains uncertain. Methods: We queried a registry of 631 CS patients evaluated at our institution to identify those with LVEF < 35% on TTE within 30 d of diagnosis and a follow-up TTE 12-18 months later (external CS diagnoses were excluded). Demographics, LVEF, NT-proBNP, GDMT, immunosuppression, CIED, and outcomes (hyperkalemia, LVAD/transplant, CV hospitalization, death) were recorded. Results: Overall, 25/631 (4%) of CS patients had an LVEF <35% at initial presentation (36% female, 84% white; median age of 58 y; probable/not biopsy-proven CS in 52%). Mean baseline LVEF was 27% (σ=7%), NT-proBNP 1736 pg/mL (n=11), potassium 4.3 mEq/L (n=18), and median NYHA Class II (54%). Patients were on a mean 1.7 GDMT agents at CS diagnosis (Figure). Most were treated with immunosuppression (88%) for mean 0.75 y, usually prednisone (88%, mean 16 mg daily) and fewer with mycophenolate (32%, mean 1875 mg daily), methotrexate (28%, mean 18mg weekly), or TNF-α inhibitor (4%). 64% were on trimethoprim-sulfamethoxazole prophylaxis. At follow-up (median 317 d), 3 patients (12%) required LVAD and 1 (4%) required heart transplant. Mean LVEF improved to 37% (excluding LVAD/transplant, σ=11%, p=0.001). CIED prevalence increased from 48 to 81% (p=0.03). Overall GDMT did not change (mean 2.0 agents, p=0.2) and only beta-blocker dose changed (64 to 138 mg mean daily metoprolol equivalents). Potassium did not change (p=0.4) and hyperkalemic events were infrequent (16%). No patients died, but unplanned hospitalization occurred in 36% of patients. Conclusions: CS patients with HFrEF are usually on partial GDMT at diagnosis, presumably due to earlier recognition of HFrEF, but intensification of GDMT may be limited. Despite improved LVEF which may be due to GDMT, immunosuppression, and/or CIED, over 1/3 patients were hospitalized within 18 mo, highlighting the high-risk profile of HFrEF in CS.

Colorectal cancer (CRC) is the third-most lethal cancer in the USA, and early detection through screening is crucial for improving outcomes. However, significant disparities in access and utilisation of CRC screening exist among patients with limited English proficiency. Our Quality Improvement (QI) team developed and implemented a video, featuring a Somali-speaking physician, created with input from internal medicine (IM) residents, patient education experts and community leaders to increase the rate of CRC screening uptake within a Somali-speaking population receiving primary care within an IM Residency Clinic. The baseline proportion of average-risk Somali-speaking patients who had successfully been screened for CRC was 46.3% (63/134). The proportion of patients agreeable to undergo CRC screening was assessed monthly from the beginning of video implementation (June 2022 to December 2022). We found that this intervention corresponded with a significant increase in willingness to undergo CRC screening from 36.4% to 100% during the early stages of intervention. At the end of our measurement timeframe, the proportion of the original population fully screened for CRC was 50.7% (68/134). Implementation of the video intervention was also assessed and determined to be minimally disruptive to the clinic flow.

Summary: Background: Peripheral artery disease (PAD) is a risk factor for adverse limb events (LE) and cardiovascular events (CVE) that coexists with type 1 (T1) and 2 (T2) diabetes mellitus (DM). Little is known about comparative risk of LE and CVE in T1/T2 DM patients with PAD. Patients and methods: We queried our database of 40,144 patients ≥18 years old who underwent ankle brachial index (ABI) measurement from 01/1996-02/2020. We isolated T1/T2 DM patients with PAD diagnosed by ankle brachial index (ABI; low [<1.0] or elevated [>1.4]) and retrieved demographics including glycated hemoglobin (HbA1c). Primary outcomes were LE (critical limb ischemia/vascular amputation) and CVE (myocardial infarction/ischemic stroke). All-cause mortality was a secondary outcome. Multivariable Cox proportional regression yielded hazard ratios (HR) with 95% confidence intervals (CI) after adjusting for pertinent risk factors including age, hypertension, hyperlipidemia, smoking, and HbA1c. Results: Our study found 10,156 patients with PAD and DM (34% T1DM, 66% T2DM) with median follow-up time 34 mo (IQR 85 mo). T1DM patients were younger than T2DM (mean age 67 vs. 70 years), with higher median HbA1c (7.7 [IQR 1.9] vs. 6.7% [IQR 1.6]), and more prevalent hypertension, hyperlipidemia, CAD, and CKD. Antiplatelet and statin use was equivocal. Elevated ABI was more common in T1DM (47 vs. 28%). LE occurred in 23% and CVE in 12% patients. LE risk was higher in T1 than T2 DM patients (HR 1.58 [95% CI 1.44, 1.73], p<0.0001), but CVE and all-cause mortality were equivocal. These observations were preserved across ABI and HbA1c subgroup analyses. Conclusions: PAD patients with T1DM had a higher LE risk than those with T2DM, even after adjustment for glycemic control and pertinent risk factors, but CVE risk and all-cause mortality were equivocal. These data suggest a potential role for more intensive LE risk modification in PAD patients with T1DM, but further investigation is needed.

Introduction: Cardiac sarcoidosis (CS) is a non-ischemic disease which can present with right ventricular (RV) dysfunction, but there is a paucity of research describing RV function and natural history in CS. Methods: We queried a registry of 512 CS patients for those with baseline and follow-up echocardiography (TTE). Demographics, medications, and baseline/follow-up TTE data were collected. RV-pulmonary arterial (RV-PA) coupling was approximated by ratio of tricuspid annular plane systolic excursion to estimated pulmonary artery systolic pressure (TAPSE:ePASP). Results: Our query yielded 343 CS patients with mean age 56y (σ=12y), who were predominantly male (67%) and white (90%) with a median follow-up 4y (interquartile range 4.1y). Most had pulmonary sarcoidosis (68%). Baseline TTE data showed left ventricular ejection fraction 48% (σ=14), abnormal RV function with RV systolic pressure (ePASP) 34 mmHg (σ=11), TAPSE 21mm (σ=5), RV S′ 0.14 m/s (σ=0.07), and RV-PA uncoupling (TAPSE:ePASP 0.69 mm/mm Hg, σ=0.25). Baseline RV function parameters did not differ by pulmonary involvement of sarcoidosis. 92% received immunosuppression and 65% received neurohormonal blockade. In long-term follow-up, the overall cohort demonstrated a trend towards worsening of both RV S’ and RV-PA coupling (P=.02 and P=.003 for linear trend, respectively) but stable ePASP (P=.11). Trends in both non-invasive ePASP and RV-PA coupling were similar in patients with and without pulmonary involvement (P=.48 and P=.79, respectively). Conclusions: In our large CS cohort with extensive follow-up, metrics of RV function and RV-PA coupling are often abnormal at CS diagnosis. Echocardiographic measures of PASP tend to remain stable but markers of RV dysfunction, including RV-PA coupling, tend to worsen throughout the disease course irrespective of pulmonary sarcoidosis. More granular phenotyping of pulmonary hypertension in CS is required to better understand this relationship.
