ABSTRACT

BACKGROUND: Age is a major risk factor for venous thromboembolism (VTE), yet patients aged ≥90 years are under-represented in clinical trials of anticoagulant therapy. The objectives were to describe and compare patient clinical characteristics, treatments, and outcomes (VTE recurrence, bleeding, and mortality) during the first 3 months of anticoagulation between VTE patients aged ≥90 years and those aged <90

METHODS: We analyzed data from the Registro Informatizado Enfermedad TromboEmbὀlica (RIETE), an ongoing global observational registry of patients with objectively confirmed acute VTE.

RESULTS: From January 2001 to October 2022, 96,701 patients were registered in RIETE, of whom 3262 (3.4%) were aged ≥90 years. Patients aged ≥90 years were less likely to be men, and to have experienced cancer or recent surgery, but more likely to manifest immobility, chronic heart failure, anemia, renal insufficiency, or dementia than those aged <90

CONCLUSIONS: In patients aged ≥90 years, the difference in the outcome of anticoagulant treatment depending on the initial presentation of VTE could suggest a need for different management approaches. Clinical trials evaluating the optimal duration of anticoagulation according to initial VTE presentation are warranted to limit excess deaths in this particular population.

Monocyte recruitment in venous pulmonary embolism at time of cancer diagnosis in upper gastrointestinal cancer patients

J Thromb Thrombolysis. 2023 Oct 4. doi: 10.1007/s11239-023-02897-5. Online ahead of print.

ABSTRACT

Upper gastrointestinal cancer is frequently complicated by venous thromboembolisms (VTE), especially pulmonary embolisms (PE) increase the mortality rate. Monocytes are a part of the innate immune system and up-regulation may indicate an ongoing inflammatory response or infectious disease and has lately been associated with a moderate risk of suffering from VTE. This prospectively study aims to compare the incidence of pulmonary embolism with markers of coagulation and compare it to the absolute monocyte count. A consecutive cohort of 250 patients with biopsy proven upper gastrointestinal cancer (i.e. pancreas, biliary tract, esophagus and gastric cancer) where included at the time of cancer diagnosis and before treatment. All patients underwent bilateral compression ultrasonography for detection of deep vein thrombosis (DVT). Of these 143 had an additionally pulmonary angiografi (CTPA) with the staging computer tomography. 13 of 250 patients (5.2%) had a DVT and 11 of 143 (7.7%) had CTPA proven PE. PE was significantly more common among patients with elevated D-dimer (OR 11.62, 95%CI: 1.13-119, P = 0.039) and elevated absolute monocyte count (OR 7.59, 95%CI: 1.37-41.98, P = 0.020). Only patients with pancreatic cancer had a significantly higher risk of DVT (OR 11.03, 95%CI: 1.25-97.43, P = 0.031). The sensitivity of absolute monocyte count was 63.6 (95%CI: 30.8-89.1) and specificity 80.3 (95%CI: 72.5-86.7), with a negative predictive value of 96.4 (95%CI: 91-99) in PE. An increased absolute monocyte count was detected in patients suffering from PE but not DVT, suggesting a possible interaction with the innate immune system.

Role of Statin Therapy in Prevention of Anthracycline-Induced Cardiotoxicity: A three dimentional echocardiography study

Curr Probl Cardiol. 2023 Oct 17:102130. doi: 10.1016/j.cpcardiol.2023.102130. Online ahead of print.

ABSTRACT

BACKGROUND: Recent advances in the treatment of breast cancer have resulted in improved overall cancer survival; however, cancer therapy related cardiac dysfunction is considered a major adverse effect of several chemotherapeutic agents, particularly anthracyclines. Hence, there is a need to develop proper cardioprotective strategies to limit myocardial injury following chemotherapy.

OBJECTIVE: To evaluate the effect of statin therapy on prevention of anthracycline- induced cardiotoxicity in female patients with breast cancer.

PATIENTS AND METHODS: The current study is a prospective, randomized, single-blind, placebo-controlled trial in which we enrolled a total of 110 female patients with newly diagnosed breast cancer who received anthracycline based chemotherapy. Patients were randomly assigned in 1:1 ratio into two groups, study group in which patients received 40 mg of oral atorvastatin and control group in which patients received placebo. A comprehensive echocardiographic examination was performed to all patients prior to receiving the chemotherapy and after 6 months, assessment of LV ejection fraction was done by 3D-echocardiography. All echocardiographers were blinded to all the patients' characteristics and assignment to either group.

RESULTS: The mean age of patients assigned to the control group was 49.8±10.51 years old, while patients assigned to the intervention group had mean age of 47.84± 9.16 years old, both the control group and the intervention group were similar in demographic data and baseline clinical characteristics. There was a highly significant difference between the two groups regarding both the absolute LVEF assessed by 3D- echocardiography at 6 months and the percentage of change compared to baseline values, patients assigned to the control group had mean LVEF of 52.92% at 6 months with percentage of change reaching -7.06%, while those assigned to the intervention group had mean LVEF reaching 56.22% at 6 months with a percentage of change reaching -3.64% (P-value: 0.008 and 0.004 for the absolute value and percentage of change respectively). There was a significant difference between the two groups regarding incidence of development of cancer therapy related cardiac dysfunction (CTRCD); defined as drop in LVEF more than 10% and to a value below 53% assessed by 3D echocardiography, among the control group 15 patients (30%) developed CTRCD after 6 months from starting Anthracyclines based chemotherapy, while, among the intervention group only 6 patients (12%) developed CTRCD. (P-value= 0.027) CONCLUSION: : Prophylactic use of atorvastatin may prevent the development of cancer therapy related cardiac dysfunction in breast cancer patients receiving anthracycline based chemotherapy.

Early Increases in Blood Pressure and Major Adverse Cardiovascular Events in Patients With Renal Cell Carcinoma and Thyroid Cancer Treated With VEGFR TKIs

J Natl Compr Canc Netw. 2023 Oct;21(10):1039-1049.e10. doi: 10.6004/jnccn.2023.7047.

ABSTRACT

BACKGROUND: Although VEGFR tyrosine kinase inhibitors (TKIs) are a preferred systemic treatment approach for patients with advanced renal cell carcinoma (RCC) and thyroid carcinoma (TC), treatment-related cardiovascular (CV) toxicity is an important contributor to morbidity. However, the clinical risk assessment and impact of CV toxicities, including early significant hypertension, among real-world advanced cancer populations receiving VEGFR TKI therapies remain understudied.

METHODS: In a multicenter, retrospective cohort study across 3 large and diverse US health systems, we characterized baseline hypertension and CV comorbidity in patients with RCC and those with TC who are newly initiating VEGFR TKI therapy. We also evaluated baseline patient-, treatment-, and disease-related factors associated with the risk for treatment-related early hypertension (within 6 weeks of TKI initiation) and major adverse CV events (MACE), accounting for the competing risk of death in an advanced cancer population, after VEGFR TKI initiation.

RESULTS: Between 2008 and 2020, 987 patients (80.3% with RCC, 19.7% with TC) initiated VEGFR TKI therapy. The baseline prevalence of hypertension was high (61.5% and 53.6% in patients with RCC and TC, respectively). Adverse CV events, including heart failure and cerebrovascular accident, were common (occurring in 14.9% of patients) and frequently occurred early (46.3% occurred within 1 year of VEGFR TKI initiation). Baseline hypertension and Black race were the primary clinical factors associated with increased acute hypertensive risk within 6 weeks of VEGFR TKI initiation. However, early significant "on-treatment" hypertension was not associated with MACE.

CONCLUSIONS: These multicenter, real-world findings indicate that hypertensive and CV morbidities are highly prevalent among patients initiating VEGFR TKI therapies, and baseline hypertension and Black race represent the primary clinical factors associated with VEGFR TKI-related early significant hypertension. However, early on-treatment hypertension was not associated with MACE, and cancer-specific CV risk algorithms may be warranted for patients initiating VEGFR TKIs.

Brugada phenocopy with altered ST-segment elevation in pericardial diffuse large B-cell lymphoma and effusive-constrictive pericarditis: a case report

Eur Heart J Case Rep. 2023 Oct 17;7(10):ytad463. doi: 10.1093/ehjcr/ytad463. eCollection 2023 Oct.

ABSTRACT

BACKGROUND: Cardiac lymphoma is a rare disease. Effusive-constrictive pericarditis can be a characteristic of pericardial involvement in patients with this disease. Conversely, a phenotype with electrocardiogram changes similar to those of Brugada syndrome is called Brugada phenocopy, and these changes improve after treatment.

CASE SUMMARY: A 71-year-old man was transported to our hospital with chest pain, hypotension, and ST-segment elevation in V1 and V2 leads during maintenance dialysis for renal failure. After arrival at the hospital, his ST-segment elevation disappeared, and emergency coronary angiography scan revealed no significant coronary artery stenoses or obstructions. His computed tomography and echocardiography scans revealed pericardial effusion and an intrapericardial mass. Further, his blood pressure dropped and ST-segment elevation recurred during dialysis after 7 days. Thus, pericardiocentesis was performed, but haemodynamic improvement was insufficient, and right catheterization findings suggested effusive-constrictive pericarditis. Meanwhile, flow cytometry of the pericardial fluid suggested the diagnosis of B-cell lymphoma; however, radical chemoradiotherapy was impossible because of cardiogenic shock. The patient died on Day 17. Further, autopsy revealed diffuse large B-cell lymphoma with pericardial and myocardial infiltration.

DISCUSSION: Cardiac lymphoma is rare but can be associated with effusive-constrictive pericarditis, which may be difficult to manage even with pericardial drainage. In such cases, radical treatment, including chemotherapy, should be promptly considered, if possible. Our patient presented with Brugada-type electrocardiogram but no syncope or family history, suggesting Brugada phenocopy and not true Brugada syndrome due to cardiac lymphoma. Notably, temporary improvement in ST-segment elevation was observed despite the absence of treatment.
