Managing thrombotic risk in patients with diabetes.

It is well known that diabetes is a prominent risk factor for cardiovascular (CV) events. The level of CV risk depends on the type and duration of diabetes, age and additional co-morbidities. Diabetes is an independent risk factor for atrial fibrillation (AF) and is frequently observed in patients with AF, which further increases their risk of stroke associated with this cardiac arrhythmia. Nearly one third of patients with diabetes globally have CV disease (CVD). Additionally, co-morbid AF and coronary artery disease are more frequently observed in patients with diabetes than the general population, further increasing the already high CV risk of these patients. To protect against thromboembolic events in patients with diabetes and AF or established CVD, guidelines recommend optimal CV risk factor control, including oral anticoagulation treatment. However, patients with diabetes exist in a prothrombotic and inflammatory state. Greater clinical benefit may therefore be seen with the use of stronger antithrombotic agents or innovative drug combinations in high-risk patients with diabetes, such as those who have concomitant AF or established CVD. In this review, we discuss CV risk management strategies in patients with diabetes and concomitant vascular disease, stroke prevention regimens in patients with diabetes and AF and how worsening renal function in these patients may complicate these approaches. Accumulating evidence from clinical trials and real-world evidence show a benefit to the administration of non-vitamin K antagonist oral anticoagulants for stroke prevention in patients with diabetes and AF.

Concept and practice of transradial 5 French percutaneous treatment of coronary bifurcation lesions.

OBJECTIVES: To assess the efficacy and safety of transradial 5 French percutaneous treatment of coronary bifurcations using conventional devices. BACKGROUND: Radial artery is smaller than femoral artery, and its size may potentially limit transradial intervention, especially when coronary anatomy is not known. METHODS: Patients with bifurcations lesions undergoing transradial 5 French ad hoc revascularization were treated according to provisional side branch (SB) stenting followed by the POT-SB dilation-final POT sequence. Only conventional devices were used. RESULTS: Overall, 80 patients (58 men, 65 ± 10 years) were enrolled. True bifurcations accounted for 64% of cases, with the left anterior descending artery/diagonal branch being the most frequent bifurcation site (n = 37, 46%) and left main coronary artery bifurcation being treated in 6 (8%) patients. Angiographic success was achieved in 78 (97.5%) patients through a 5 French guiding catheter whereas in two cases, a 5-6 French guiding catheter upgrade was required to optimize SB treatment after the main bifurcation vessel have been secured. Overall, procedural success was achieved in all but one patient who had periprocedural necrosis following multivessel PCI. Another patient underwent target bifurcation revascularization because of a critical restenosis in a significant SB yielding an acute coronary syndrome five months after the index procedure. CONCLUSIONS: This study demonstrates the feasibility of transradial 5 French bifurcation intervention with nondedicated devices and preliminary supports its efficacy and safety over a wide range of bifurcation anatomy and complexity.

Angiographic and clinical performance of polymer-free biolimus-eluting stent in patients with ST-segment elevation acute myocardial infarction in a metropolitan public hospital: The BESAMI MUCHO study.

OBJECTIVES: This study aimed at assessing the performance of a new generation polymer-free biolimus-eluting stent (BES) in real-world patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Polymers components of early-generation drug-eluting stents have been implicated in the pathogenesis of delayed arterial healing, vessel remodeling, and delayed stent thrombosis. Recently, a novel polymer-free BES has shown excellent clinical performance in clinical trial setting. METHODS: Overall, 175 consecutive patients (64 ± 14 years, 141 men) treated with the BioFreedom (Biosensors Europe, Morges, Switzerland) polymer-free BES because of STEMI were included in this study. The primary endpoint was the rate of major adverse cardiac events (MACE), a composite of cardiac death, recurrent myocardial infarction, and ischemia-driven target vessel revascularization at 1 year follow-up. A subgroup of patients underwent 6-month angiographic follow-up. Dual antiplatelet therapy was prescribed for 12 months after STEMI. RESULTS: At 1 year, the cumulative rate of MACE was 4.6%. One patient (0.6%) had an arrhythmic cardiac death and five (2.9%) had ischemia-driven target vessel revascularization, although only three (1.7%) had target lesion revascularization. Two (1.1%) patients had acute stent thrombosis yielding nonfatal myocardial infarction. In 70 patients (63 ± 14 years, 61 men), quantitative coronary angiography at 6-month follow-up revealed diameter stenosis of 24.1 ± 13.7% and minimal lumen diameter of 2.29 ± 0.56 mm, yielding a late lumen loss of 0.13 ± 0.14 mm. CONCLUSIONS: In real-world setting, implantation of a new-generation polymer-free BES during STEMI is associated with favorable clinical and angiographic results, pointing toward the overall efficacy and safety of the device in complex clinical scenarios.

Prospective multicentre clinical performance evaluation of second and third generation zotarolimus-eluting stents to treat patients with bifurcated coronary lesions.

AIM: To assess the "real world" clinical outcome of patients with bifurcated lesions undergoing percutaneous coronary intervention with implantation of second and third generations of zotarolimus-eluting stent. METHODS AND RESULTS: Nine Italian centres participated in a prospective multicentre clinical project evaluating the outcome of patients receiving zotarolimus-eluting Resolute stent and Resolute Integrity stents. Patients with bifurcated lesions entered this evaluation. Clinical characteristics and angiographic and procedural details were prospectively recorded. Clinical outcome was prospectively assessed to evaluate the occurrence of major adverse cardiac events (MACE). A total of 577 patients were enrolled. The target lesion was distal left main in 11.1% and left anterior descending artery in 52.8%, and 30.3% of lesions were Medina 1,1,1. At a mean follow-up time of 27.0 ± 13.5 months, the survival free from MACE was 91.8%. Survival free from MACE was similar in patients grouped according to different bifurcated lesion complexity. On the contrary, patients receiving a single stent had better survival free from MACE as compared with those with double stent (P = 0.005). At multivariable analysis, double stenting (but not bifurcated lesion complexity) was found to be a significant predictor of MACE (hazard ratio, 2.52; 95% confidence interval, 1.28-4.94; P = 0.007). Of note, patients receiving the second stent as a bail-out had worse survival free from MACE compared with those who received it as a planned technique (P = 0.045). CONCLUSION: The treatment of patients with bifurcated lesions with second and third generation zotarolimus-eluting stents is associated with good long-term clinical outcomes. Clinical outcome seems to be independent of lesion complexity, but may be influenced by the stenting technique (single or double stenting as well as elective or bail-out double stenting). © 2015 Wiley Periodicals, Inc.

One-year follow-up of patients treated with new-generation polymer-based 38 mm everolimus-eluting stent: the P38 study.

OBJECTIVES: To assess the clinical outcome at 1-year follow-up of real-world patients with long coronary lesions treated with the 38 mm Xience Prime (Abbott Vascular) everolimus-eluting stent (EES). BACKGROUND: Long-lesions present special challenges to the interventional cardiologists, including increased risk of restenosis, periprocedural injury, geographical miss, and stent deliverability. Indeed, results obtained with shorter stent in the treatment of simpler lesions are of limited applicability to longer stents. METHODS: Consecutive patients presenting with a long coronary lesion treated by percutaneous coronary intervention with at least one implanted 38 mm EES were enrolled in the study. Their clinical data were prospectively registered. Major adverse cardiac events (MACE) were defined as a composite of cardiac death, nonfatal myocardial infarction (according to the Universal Definition) and target vessel revascularization. Stent thrombosis was defined according to the Academic Research Consortium criteria. RESULTS: Overall, 203 real-world patients (152 men, 68 ± 9 years) were enrolled in the P38 Study. At 1-year follow-up, 6 (3.0%) patients had died from cardiac causes, 7 (3.4%) had a nonfatal myocardial infarction and 8 (3.9%) underwent target vessel revascularization, yielding a 10.3% cumulative rate of MACE. Two patients had a stent thrombosis (one definite and one probable). No significant differences in event rates were found between patients with and without an additional stent implanted overlapping the 38 mm one. CONCLUSIONS: The use of a new-generation polymer-based 38 mm EES in a real-world population with unselected long lesions is associated with excellent procedural results and good clinical outcomes at 12-month follow-up.

Efficacy of Modern Therapies for Heart Failure with Reduced Ejection Fraction in Specific Population Subgroups: A Systematic Review and Network Meta-Analysis.

INTRODUCTION: The efficacy and safety of emerging therapies for heart failure with reduced ejection fraction (HFrEF) have never been compared in specific subgroups of patients. METHODS: PubMed, Cochrane Registry, Web of Science, Scopus, and EMBASE libraries were used to extract data. We used the following keywords: (heart failure with reduced ejection fraction OR HFrEF) AND (treatment OR therapy) OR (cardiovascular death) OR (hospitalization for heart failure). We compared randomized clinical trials for HFrEF emerging therapies focusing on the elderly (patients >65 years old and >75 years old), chronic kidney disease (CKD) (estimated glomerular filtration rate (eGFR) < 60 mL/min), patients with diabetes mellitus (DM), coronary heart disease (CAD), New York Heart Association (NYHA) class III/IV, women, patients on sacubitril/valsartan (S/V). The primary outcome was the efficacy composite endpoint of cardiovascular death (CVD) and HF hospitalization (HFH). RESULTS: S/V significantly reduced the primary outcome in patients >65 years old (RR: 0.80; 95% CI: 0.68-0.94) and with CKD (RR: 0.79; 95% CI: 0.69-0.90); dapagliflozin in patients >65 (RR: 0.72; 95% CI: 0.60-0.86) and >75 years old (RR: 0.68; 95% CI: 0.53-0.87), in those with CKD (RR: 0.72; 95% CI: 0.59-0.88), DM (RR: 0.75; 95% CI: 0.63-0.89), and CAD (RR: 0.77; 95% CI: 0.65-0.92); empagliflozin in patients >65 years old (RR: 0.78; 95% CI: 0.66-0.93), those with DM (RR: 0.72; 95% CI: 0.60-0.86), CAD (RR: 0.82; 95% CI: 0.68-0.99), women (RR: 0.59; 95% CI: 0.44-0.79), and in patients on S/V (RR: 0.64; 95% CI: 0.45-0.91); vericiguat in patients with CKD (RR: 0.84; 95% CI: 0.73-0.97) and NYHA class III/IV (RR: 0.87; 95% CI: 0.77-0.98); omecamtiv mecarbil in patients with CAD (RR: 0.90; 95% CI: 0.82-0.99) and NYHA III/IV (RR: 0.88; 95% CI: 0.80-0.97). CONCLUSION: Emerging HFrEF therapies show a clinical benefit with the reduction of the primary composite endpoint of CVD and HFH, with each drug being more effective in specific patient population.

Radial versus femoral approach comparison in percutaneous coronary intervention with intraaortic balloon pump support: the RADIAL PUMP UP registry.

BACKGROUND: The role of intraaortic balloon pump (IABP) during percutaneous coronary intervention (PCI) in high-risk acute patients remains debated. Device-related complications and the more complex patient management could explain such lack of clinical benefit. We aimed to assess the impact of transradial versus transfemoral access for PCI requiring IABP support on vascular complications and clinical outcome. METHODS: We retrospectively analyzed 321 consecutive patients receiving IABP support during transfemoral (n = 209) or transradial (n = 112) PCI. Thirty-day net adverse clinical events (NACEs) (composite of postprocedural bleeding, cardiac death, myocardial infarction, target lesion revascularization, and stroke) were the primary end point, with access-related bleeding and hospital stay as secondary end points. RESULTS: Cardiogenic shock and hemodynamic instability were the most common indications for IABP support. Cumulative 30-day NACE rate was 50.2%, whereas an access site-related bleeding occurred in 14.3%. Patients undergoing transfemoral PCI had a higher unadjusted rate of NACEs when compared with the transradial group (57.4% vs 36.6%, P < .01), mainly due more access-related bleedings (18.7% vs 6.3%, P < .01). Such increased risk of NACEs was confirmed after propensity score adjustment (hazard ratio 0.57 [0.4-0.9], P = .007), whereas hospital stay appeared comparable in the 2 groups. CONCLUSIONS: In this observational registry, high-risk patients undergoing PCI and requiring IABP support appeared to have fewer NACEs if transradial access was used instead of transfemoral, mainly due to fewer access-related bleedings. Given the inherent limitations of this retrospective work, including the inability to adjust for unknown confounders, further controlled studies are warranted to confirm or refute these findings.

Closed versus open cell stent for high-risk percutaneous coronary interventions in ST-elevation acute myocardial infarction: the Closed versus Open Cells stent for High risk percutaneous coronary Interventions in ST-Elevation acute myocardial infarction (COCHISE) pilot study.

BACKGROUND: Stent deployment may be associated with distal embolization and slow flow in coronary thrombotic lesions. There are no data on the risk of distal thrombus embolization according to the stent design. The aim was to evaluate coronary flow after percutaneous coronary interventions (PCI) in acute myocardial infarction according to the employed stent (closed versus open cell design). METHODS: From March 2010 to December 2011, 223 consecutive patients with acute ST-elevation myocardial infarction were randomized to primary PCI either with an open cell (112 patients, 88 men) or with a closed cell stent design (111 patients, 92 men). The primary endpoint was the corrected TIMI frame count (cTFC) after the procedure. RESULTS: There were no significant differences in procedural success nor in-stent deployment in the 2 groups. At baseline, there were no significant differences in cTFC between the 2 groups (70 ± 37 and 67 ± 39, P = .65, respectively). After the procedure, the open cell group showed significantly higher cTFC compared to the closed cell group (18 ± 11 and 15 ± 5, P = .003 respectively). This difference was associated with a significant lower rate of TIMI 3 flow (87% and 95%, P = .037) and myocardial blush grade 3 (65% and 87%, P = .001) in the open compared to the closed cell group. There were 2 cases of death in the open cell and 1 case in the closed cell group. CONCLUSIONS: The use of a closed cell stent design rather than an open cell during PCI for acute ST-elevation myocardial infarction is associated with better coronary angiographic flow after PCI.

Pharmacoeconomic impact evaluation of statin adherence in high-risk unselected post myocardial infarction population: an administrative database-guided analysis.

BACKGROUND: The compliance to statins in secondary prevention is very low, increasing health-care costs principally for rehospitalization. OBJECTIVES: To evaluate the cost of lack of persistence to statin therapy together with identification and cost-estimation of poor compliance. METHODS: Retrospective observational study starting from administrative database analysis of statin prescription after myocardial infarction. RESULTS: Among 463 patients enrolled, 25.1% were never treated, 70.8% received statins regularly; 14.9% received only 1-2 prescriptions (spot prescription), and 12% were occasional users. Among the 288 nonoccasional users, we found a compliance rate of 80% only in the 59.7%. The cost analysis shows that 59.787,72 euros (23.4%) have been spent for patients with compliance of less than 80% (ineffective adherence). CONCLUSIONS: As the lower compliance affects the health-care costs, the identification of occasional users and spot prescriptions of the nonoccasional users, has a potential role in reducing medical expense with limited increase in costs.

Dual pathway inhibition in atherothrombosis prevention: yes, now we can!

Despite ongoing developments, prevention and treatment of atherothrombotic cardiovascular disease remains a common challenge. Antithrombotic options for cardiocerebrovascular disease prevention involves a choice between dual antiplatelet therapy (DAPT) and dual pathway inhibition (DPI), which includes an antiplatelet agent and a reduced dose anticoagulant agent. In selected patients at high risk of event and low risk of bleeding, especially those undergoing recent and complex coronary revascularization using drug-eluting stents (DES) ("revascularization-driven effect"), DAPT is superior to single antiplatelet therapy with aspirin. DPI involves a wider potential range of treatment and is superior to single antiplatelet therapy with aspirin, particularly in patients with atherothrombotic involvement in different vascular beds both previously revascularized and not ("no revascularization-driven effect"). After nearly thirty years of randomized trials and observational registries, we have sufficient data to customize antithrombotic therapy in patients at high cardiovascular risk. Therefore, "atherothrombosis stakeholders" must identify the right patient for the right therapy to ensure high levels of efficacy and safety with the best of current therapeutic opportunities.

New Challenges in Heart Failure with Reduced Ejection Fraction: Managing Worsening Events.

Patients with an established diagnosis of heart failure (HF) with reduced ejection fraction (HFrEF) are prone to experience episodes of worsening symptoms and signs despite continued therapy, termed "worsening heart failure" (WHF). Despite guideline-directed medical therapy, worsening of chronic heart failure accounts for almost 50% of all hospital admissions for HF, and patients experiencing WHF carry a substantially higher risk of death and hospitalization than patients with "stable" HF. New drugs are emerging as arrows in the quiver for clinicians to address the residual risk of HF hospitalization and cardiovascular deaths in patients with WHF. This question-and-answer-based review will discuss the emerging definition of WHF in light of the recent clinical consensus released by the Heart Failure Association (HFA) of the European Society of Cardiology (ESC), the new therapeutic approaches to treat WHF and then move on to their timing and safety concerns (i.e., renal profile).

Simultaneous transradial coronary and renal in stent restenosis treatment in diabetic patient with NSTEMI complicated by hypertensive emergency.

The elderly diabetic patients are increasingly referred for percutaneous coronary interventions during acute coronary syndromes. A nonegligible proportion of this population includes the in stent restenosis as a possible cause of ischemic syndrome. This population accounts an higher risk of ischemic, bleeding and vascular complications affecting the periprocedural management, the length of hospital stay and also the prognosis. The improvement of strategies concerning site of access choice, antithrombotic drug and timing of interventional treatment have significantly reduced the incidence of complications. This paper reports the case of a 76 years-old diabetic female with a high bleeding risk, referred to our hospital because of NSTEMI complicated by pulmonary edema during hypertensive emergency. The patient had a simultaneous in stent restenosis both in left descending coronary artery and left renal artery, undergoing percutaneous transradial treatment during bivalirudin infusion. The clinical, technical, pharmacological and prognostic implications are discussed.

Five Years of Direct Oral Anticoagulants Use in Italy: Adverse Drug Reactions from the Italian National Pharmacovigilance Network.

BACKGROUND: Direct oral anticoagulants (DOACs) are the preferred anticoagulant drugs for the prevention of atrial fibrillation (AF)-related thromboembolic complications and for the treatment and the prevention of recurrences of venous thromboembolism (VTE). The evaluation of self-reported adverse drug reactions (ADRs) available from databases of drug-regulatory agencies such as the Italian Medicines Agency (AIFA) pharmacovigilance database represents a novel aid to guide decision making. OBJECTIVE: To assess the safety profile of DOACs by analyzing ADR rates in the real-world Italian scenario. METHODS: Post-marketing surveillance data recorded by the National Pharmacovigilance Network were retrieved for the time period 2017-2021 from the AIFA online site. The following data were collected for each DOAC: total ADR number, serious ADR number, gastrointestinal (GI) ADR, intracranial hemorrhage events (ICH ADR), and more frequently reported ADR for the study year. The safety profile was expressed by the risk index (RI). RESULTS: Rivaroxaban use was associated with consistent and stable low rates of serious ADR, GI ADR, and ICH ADR across the 5-year study period. Rivaroxaban and apixaban showed the lowest RI for serious ADR and GI ADR, while rivaroxaban use was associated with significantly lower ICH events as compared to apixaban. Dabigatran was related to the highest RIs for every ADR class, in particular GI ADRs. CONCLUSIONS: DOACs presented an acceptable safety profile in the current post-market analysis. However, rivaroxaban and apixaban were associated with more favorable safety profiles as compared to dabigatran, while rivaroxaban provoked statistically significantly fewer ICH events as compared to apixaban.

Transradial approach (left vs right) and procedural times during percutaneous coronary procedures: TALENT study.

BACKGROUND: most of the studies assessing transradial approach for coronary angiography (CA) have been performed through right radial approach (RRA). Our aim was to evaluate the safety and efficacy of left radial approach (LRA) compared with RRA for coronary procedures. METHODS: from January 2009 to December 2009, in 2 hospitals, 1,540 patients were randomized to RRA (770 patients) or LRA (770 patients) for percutaneous coronary procedures. The primary end point was fluoroscopy time for CA and for percutaneous coronary intervention (PCI) evaluated independently. Prespecified subgroup analyses according to patient age and operator experience were planned. RESULTS: in 1,467 patients (732 RRA and 735 LRA), a CA (diagnostic group) was performed, and in 688 (344 each for RRA and LRA), a PCI. In the diagnostic group, LRA was associated with significantly lower fluoroscopy time (149 seconds, interquartile range [IQR] 95-270 seconds) and dose area product fluoroscopy (10.7 Gy cm(2), IQR 6-20.5 Gy cm(2)) compared with the RRA (168 seconds, IQR 110-277 seconds, P = .0025 and 12.1 Gy cm(2), IQR 7-23.8 Gy cm(2), P = .004, respectively). In the PCI group, there were no significant differences in fluoroscopy time (614 seconds, IQR 367-1,087 seconds for LRA and 695 seconds, IQR 415-1,235 seconds, P = .087 for RRA) and dose area product fluoroscopy (53.7 Gy cm(2), IQR 29-101 Gy cm(2) for LRA and 63.1 Gy cm(2), IQR 31-119 Gy cm(2), P = .17 for RRA). According to subgroup analyses, the differences between LRA and RRA were confined to older patients (≥ 70 years old) and to operators in training. CONCLUSIONS: left radial approach for coronary diagnostic procedures is associated with lower fluoroscopy time and radiation dose adsorbed by patients compared with the RRA, particularly in older patients and for operators in training.

The PREHAMI (PREsillion™ in high-risk acute myocardial infarction) registry: in-hospital and long-term outcomes.

OBJECTIVES: To evaluate the efficacy of the new Cobalt-Chromium (Co-Cr) Presillion™ stent for the treatment of high-risk acute myocardial infarction (MI) patients. BACKGROUND: Percutaneous coronary intervention (PCI) with stent represents the gold standard treatment for acute MI. METHODS AND RESULTS: We enrolled patients with high-risk acute MI (either ST-segment elevation MI or non-ST-segment elevation MI) treated with PCI using a new Co-Cr bare metal stent with closed cells design and limited balloon compliance. We considered high-risk features as one of the following: age ≥ 70 years, ejection fraction ≤ 35%, glomerular filtration rate ≤ 60 mL/min, diabetes mellitus, rescue PCI, or chronic atrial fibrillation or other conditions requiring long-term oral anticoagulation therapy. Primary outcome of the study was rate of major adverse cardiac events (MACE) defined as all-cause death, new MI, and target-vessel revascularization. A total of 129 consecutive patients were enrolled (69 ± 11 years, 74% men): 71 (55%) patients with ST-segment elevation MI and 58 (45%) patients with non-ST-segment elevation MI. A total of 153 vessels (169 lesions and 179 stents) were treated. The device success rate was high (98.8%). In-hospital MACE rate was 5.4% mainly because of death associated with the acute MI. At 1-year follow-up, the MACE rate was 17.3%, with 11% all-cause death (7.9% of cardiac origin), 0.6% of stent thrombosis, and 4.6% target-vessel revascularization. CONCLUSIONS: The use of the Co-Cr Presillion stent in patients with high-risk acute MI treated invasively seems to be safe and efficacious with optimal deliverability and good long-term outcomes and represents a good option in the treatment of these patients.

New evidence of direct oral anticoagulation therapy on cardiac valve calcifications, renal preservation and inflammatory modulation.

BACKGROUND: Rivaroxaban is a direct inhibitor of activated Factor X (FXa), an anti-inflammatory protein exerting a protective effect on the cardiac valve and vascular endothelium. We compare the effect of Warfarin and Rivaroxaban on inflammation biomarkers and their contribution to heart valve calcification progression and renal preservation in a population of atrial fibrillation (AF) patients with chronic kidney disease (CKD) stage 3b - 4. METHODS: This was an observational, multicenter, prospective study enrolling 347 consecutive CKD stage 3b - 4 patients newly diagnosed with AF: 247 were treated with Rivaroxaban and 100 with Warfarin. Every 12 months, we measured creatinine levels and cardiac valve calcification via standard trans-thoracic echocardiogram, while plasma levels of inflammatory mediators were quantified by ELISA at baseline and after 24 months. RESULTS: Over a follow-up of 24 months, long-term treatment with Rivaroxaban was associated with a significative reduction of cytokines. Patients treated with Rivaroxaban experienced a more frequent stabilization/regression of valve calcifications comparing with patients treated with Warfarin. Rivaroxaban use was related with an improvement in kidney function in 87.4% of patients, while in those treated with Warfarin was reported a worsening of renal clearance in 98% of cases. Patients taking Rivaroxaban experienced lower adverse events (3.2% vs 49%, p-value <0.001). CONCLUSIONS: Our findings suggest that Rivaroxaban compared to Warfarin is associated with lower levels of serum markers of inflammation. The inhibition of FXa may exert an anti-inflammatory effect contributing to reduce the risk of cardiac valve calcification progression and worsening of renal function.

[Indicators of statin use as a model for qualitative evaluation of chronic disease management in the Local Health Unit Roma B]. / Indicatori di farmacoutilizzazione nel trattamento con Statine come modello per la valutazione qualitativa nella gestione delle patologie croniche nell'Asl Roma B.

In chronic diseases the adherence and persistence to therapeutic treatments are often lower than guidelines said. This leads to a worse therapeutic effect of the treatments and to a misuse in healthcare costs. Our study evaluates the impact of a pharmacoutilization analysis model, derived from the administrative database of the Local Health Unit Roma B. In particularly we calculate some indicators of adherence, persistence, occasional treatment and switch in patients on statins secondary prevention treatment (patients discharged from Hospital with Acute Myocardial Infarction diagnosis). The model that we developed would be successfully used in the cost-effective analysis of other drugs.

Predictors of Residual Right-to-Left Shunt After Percutaneous Suture-Mediated Patent Fossa Ovalis Closure.

OBJECTIVES: This study sought to assess patent fossa ovalis (PFO) anatomy by transesophageal echocardiography (TEE) in patients undergoing percutaneous suture-mediated PFO closure to identify predictors of post-procedural residual atrial right-to-left shunt (RLS). BACKGROUND: Percutaneous suture-mediated PFO closure has been proven to be a safe and effective technique in most PFO patients. METHODS: From June 2016 to October 2019, 247 consecutive patients underwent percutaneous suture-mediated PFO closure at our institution. Of them, 230 (46 ± 13 years of age, 146 women) had complete and technically evaluable pre-procedural TEE. The following parameters in short-axis view were assessed: presence and grade of spontaneous RLS, PFO length and width, presence of atrial septal aneurysm and its maximal bulge, and presence of an embryonic or fetal remnant (Chiari network or Eustachian valve). RESULTS: At the first follow-up transthoracic echocardiography performed between 3 and 6 months from the closure procedure, a residual RLS ≥2 grade was found in 37 (16%) patients. Grade of pre-procedural spontaneous RLS (hazard ratio: 1.99; 95% confidence interval: 1.14 to 3.48; p = 0.016) shunt and PFO width (hazard ratio: 2.52; 95% confidence interval: 1.85 to 3.43; p < 0.001) were both found to be significantly associated with significant residual RLS at multivariable analysis. The presence of atrial septal aneurysm and its maximal bulge and of congenital remnants was not associated with significant residual RLS. CONCLUSIONS: Percutaneous suture-mediated PFO closure is feasible in the majority of septal anatomies; however, PFO >5 mm in width and spontaneous large RLS are less likely to be closed with 1 stitch only.

Angiographic and clinical outcome of invasively managed patients with thrombosed coronary bare metal or drug-eluting stents: the OPTIMIST study.

AIMS: Stent thrombosis (ST) is a major complication of percutaneous coronary interventions (PCIs). An invasive management by re-PCI is the commonly adopted treatment for ST, but data on outcome are limited. METHODS AND RESULTS: We performed a 2-year multicentre registry enrolling consecutive patients with angiographically confirmed ST undergoing PCI. The primary angiographic endpoint was optimal angiographic reperfusion (TIMI 3 + blush grade 2 or 3). The primary clinical endpoints were death and major adverse coronary and cerebrovascular events (MACCEs) at 6 months. A total of 110 patients underwent 117 urgent PCI during the study. Patients with drug-eluting stent (DES) thrombosis, compared with those with bare metal stent (BMS) thrombosis, exhibited a higher rate of late or very late presentation and of anti-platelet therapy withdrawal. Optimal angiographic reperfusion was obtained in 64% of the patients. Death and MACCE rates at 6 months were 17 and 30%, respectively. Clinical outcome was similar for BMS and DES thrombosis. Very late ST, implantation of stent during PCI for ST, and failure to achieve optimal angiographic reperfusion were the independent predictors of 6-month mortality. CONCLUSION: DES and BMS thromboses have different clinical features, but a similar poor outcome. Indeed, PCI for ST is associated with a low rate of reperfusion and to a high rate of death and MACCE, calling for action in order to prevent its occurrence and to improve its management.

Safety and Efficacy of Triple Therapeutic Targets with Rivaroxaban after Acute Myocardial Infarction Complicated by Left Ventricular Thrombi in a Case of Nonvalvular Atrial Fibrillation.

We present the complex case of a high-risk patient with nonvalvular atrial fibrillation, who experienced a non-ST elevation myocardial infarction complicated by left ventricular (LV) thrombi and underwent percutaneous coronary intervention with drug-eluting stent implantation. The patient was initially treated with short-term triple therapy including aspirin, clopidogrel, and rivaroxaban 15 mg/die. Following aspirin dropping one month after discharge, the patient continued on dual therapy with clopidogrel and rivaroxaban, and a clinical and imaging follow-up at 6 and 12 months confirmed the LV thrombi resolution, with no thromboembolic episodes and a good safety profile.
