Management of Acute Coronary Syndrome in Cancer Patients: It's High Time We Dealt with It.

Cancer patients have an increased risk of cardiovascular disease and, notably, a significant prevalence of acute coronary syndrome (ACS). It has been shown that an elevated presence of cardiovascular risk factors in this setting leads to an interaction between these two conditions, influencing their therapeutic strategies and contributing to higher mortality. Nonetheless, cancer patients have generally not been evaluated in ACS trials, so that the treatment in these cases is still not fully known. We reviewed the current literature and discussed the best management for these very high-risk patients. The treatment strategy must be tailored based on the cancer type and stage, balancing thrombotic and bleeding risks. When the prognosis is longer than six months, especially if a clinical instability coexists, patients with ACS and cancer should be referred for percutaneous coronary intervention (PCI) as soon as possible. Moreover, an invasive strategy should be preferred in STEMI patients as well as in NSTEMI patients who are considered as high risk. On the contrary, in clinically stable NSTEMI patients, a conservative non-invasive strategy could be adopted, especially in cases of a poor life expectancy and/or of high risk of bleeding. Drug-Eluting-Stents (DES) should be the first choice if an invasive strategy is adopted. Conservative therapy could instead be considered in cancer patients with more stable CAD at an increased risk of major bleeding complications. However, the duration of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is recommended, but it should be as short as possible, whereas triple antithrombotic therapy is non-advised because it significantly increases the risk of bleeding. ACS management among cancer patients should be based on an accurate evaluation of the risk of thrombosis and bleeding. Future studies focused on choosing optimal strategies in tumor patients with ACS should be performed to treat this subset of patients better.

Update on Management of Cardiovascular Diseases in Women.

Cardiovascular diseases (CVD) have a lower prevalence in women than men; although, a higher mortality rate and a poorer prognosis are more common in women. However, there is a misperception of CVD female risk since women have commonly been considered more protected so that the real threat is vastly underestimated. Consequently, female patients are more likely to be treated less aggressively, and a lower rate of diagnostic and interventional procedures is performed in women than in men. In addition, there are substantial sex differences in CVD, so different strategies are needed. This review aims to evaluate the main gender-specific approaches in CVD.

Anticoagulation in Atrial Fibrillation Cardioversion: What Is Crucial to Take into Account.

The therapeutic dilemma between rhythm and rate control in the management of atrial fibrillation (AF) is still unresolved and electrical or pharmacological cardioversion (CV) frequently represents a useful strategy. The most recent guidelines recommend anticoagulation according to individual thromboembolic risk. Vitamin K antagonists (VKAs) have been routinely used to prevent thromboembolic events. Non-vitamin K antagonist oral anticoagulants (NOACs) represent a significant advance due to their more predictable therapeutic effect and more favorable hemorrhagic risk profile. In hemodynamically unstable patients, an emergency electrical cardioversion (ECV) must be performed. In this situation, intravenous heparin or low molecular weight heparin (LMWH) should be administered before CV. In patients with AF occurring within less than 48 h, synchronized direct ECV should be the elective procedure, as it restores sinus rhythm quicker and more successfully than pharmacological cardioversion (PCV) and is associated with shorter length of hospitalization. Patients with acute onset AF were traditionally considered at lower risk of thromboembolic events due to the shorter time for atrial thrombus formation. In patients with hemodynamic stability and AF for more than 48 h, an ECV should be planned after at least 3 weeks of anticoagulation therapy. Alternatively, transesophageal echocardiography (TEE) to rule out left atrial appendage thrombus (LAAT) should be performed, followed by ECV and anticoagulation for at least 4 weeks. Theoretically, the standardized use of TEE before CV allows a better stratification of thromboembolic risk, although data available to date are not univocal.

[Cardiology units and organizational models of heart transplantation centers in Italy: a survey by the Italian Association of Hospital Cardiologists-Italian Society of Organ Transplantation (ANMCO-SITO)]. / Cardiologie e modelli organizzativi dei centri trapianto di cuore: indagine ANMCO-SITO.

BACKGROUND: The extent and quality of the involvement of cardiology units in health programs delivered by Italian centers for heart transplantation (HTx) have not been investigated previously. METHODS: The Italian Association of Hospital Cardiologists (ANMCO) and the Italian Society for Organ Transplantation (SITO) developed and delivered a nationwide survey to the Directors of the Italian centers for HTx to investigate the extent to which cardiology units contribute to HTx programs. The survey investigated: (i) the organization of the centers and institutional frame under which cardiology units contributed to HTx programs; (ii) the volumes of procedures and clinical services delivered by cardiology units to HTx centers for listing patients, following those waiting for HTx, managing acute heart failure, selecting and allocating organs to recipients, following and managing organ rejection after HTx. RESULTS: Of the 14 Italian centers involved, 13 provided full responses to the survey. Between 2017-2019, on average, 46% of the respondents performed up to 15 HTx/year, and additional 46% performed between 16 and 30 HTx/year. Of the respondents, 62% were included in a department of cardiac Surgery which did not include a cardiology unit; furthermore, 54% declared not to be included in a formal network for heart failure management. Cardiology units were the source for referrals of candidates to HTx in 85% cases. Of the respondents, 15% declared to be able to provide cardiological services thorough intra-center multidisciplinary team including cardiologists, whereas cardiological services were outsourced in 61% of the respondents. The clinical follow-up of patients waiting for HTx was performed directly by surgeons in 38% of the respondents. Worsening heart failure was managed directly by the HTx center in 33% of the cases using dedicated beds. Post-HTx follow-up, including endomyocardial biopsy, involved external cardiology units in less than 25% of the centers. CONCLUSIONS: The ANMCO-SITO survey shows that in Italy a very wide variability exists in terms of organization of HTx centers and their relationships with cardiology units for delivering specific cardiological services and procedures. In large majority, patient referral to HTx centers is mediated by cardiology units, whereas HTx was rarely included in a structured cardiological network for heart failure management.

Effects of L-arginine on the Minnesota Living with Heart Failure Questionnaire quality-of-life score in patients with chronic systolic heart failure.

BACKGROUND: L-arginine, the precursor of nitric oxide, may restore nitric oxide levels and bioavailability and influence symptom severity, quality of life (QoL), physical performance, and left ventricular (LV) diastolic abnormalities in patients with chronic systolic heart failure (HF). The aim was to evaluate the effects of orally administered L-arginine in chronic HF patients. MATERIAL/METHODS: A parallel double-blind multicenter randomized study was performed in 68 patients (mean age: 64+/-11 years) with mild-to-moderate systolic HF (NYHA class II-III) and LV ejection fraction (EF)

Pergolide protects SH-SY5Y cells against neurodegeneration induced by H(2)O(2).

We found that pergolide, a dopamine D1/D2 receptor agonist used in the clinical therapy of Parkinson's disease, protects SH-SY5Y neuroblastoma cells from cell death induced by a brief pulse (15 min) of 1 mM H(2)O(2). Neuroprotection was found when pergolide was added to the culture medium either simultaneously with (EC(50)=60 nM) or 2 h before (EC(50)=40 nM) H(2)O(2) treatment. These effects were not blocked by different dopamine receptor antagonists. Our data suggest that pergolide, independently of dopamine receptor stimulation, may interfere with the early phases of the oxidative stress-induced neurotoxic process.
