RESUMO

BACKGROUND: The COVID-19 pandemic with the stay-at-home orders and lockdown has dramatically forced athletes to stop team training and competitions, causing deep changes in habits and lifestyle. Aim of this study was to evaluate in a retrospective single center study the cardiovascular (CV) health and fitness of elite football player after COVID-19 lockdown in Italy and to compare such findings with the 2019 off-season period, in order to identify potential differences in the CV features and outcomes. METHODS: All 29 professional football players of the first male team were enrolled before resuming training and competition after COVID-19 lockdown and underwent several exams including physical examination, resting and stress electrocardiography (ECG), echocardiography, spirometry and blood tests. RESULTS: Median age was 27 years (23; 31), with no athlete being COVID-19 positive at the time of the evaluation. In comparison with the usual off-season 2-month detraining, significant differences were found for left ventricular (LV) mass (189 g [172; 212] vs. 181 g [167; 206], P=0.024) and LV Mass Index for body surface area (94 g/m2 [85; 104] vs. 88 g/m2 [79.5; 101.5], P=0.017), while LV mass/fat free mass remained unchanged (2.8 g/kg [2.6; 2.9] vs. 2.9 g/kg [2.6; 3.2], P=0.222). Respiratory function and metabolic profile were improved, while no significant changes were found in ECG findings, at rest and during exercise. CONCLUSIONS: Prolonged abstinence from training and competitions induced by lockdown elicited significant changes in comparison with off-season in parameters ascribable to detraining, as the changes in LV mass, in respiratory function and in metabolic profile.

RESUMO

OBJECTIVES: To investigate a possible independent predictive role of systemic inflammation markers on renal function after renal artery stenting. BACKGROUND: An elevated baseline serum creatinine has previously been shown to be the strongest predictor of improved renal function after percutaneous renal artery stenting. The inflammatory system is implicated in every stage of chronic kidney disease, and we hypothesized an additional value of markers of systemic inflammation in predicting response after renal artery stenting. METHODS: This single center, prospective study includes 62 consecutive patients with chronic kidney disease at stage ≥ 3 or resistant hypertension who underwent stent placement for 74 angiographically significant atherosclerotic renal lesions. Inflammatory markers, including serum C-reactive protein (CRP), erythrocyte sedimentation rate, and white blood cell count were determined prior to renal angioplasty and related to changes in renal function at follow-up. RESULTS: Six-month clinical follow up was completed in 57 patients. Overall, median serum creatinine concentration exhibited a non significant reduction from 1.40 mg/dl (quartiles: 1.20, 1.75 mg/dl) at baseline to 1.30 mg/dl (quartiles: 1.1, 1.55 mg/dl) at 6 months (p=0.17). Significant multivariate independent predictors of decreased creatinine included higher baseline serum creatinine levels (adjusted OR per quartile increment, 2.5 [1.3 to 4.7], p=0.004) and lower C-reactive protein levels (adjusted OR per quartile increment 0.39 [0.19 to 0.82], p=0.013). CONCLUSIONS: Patients with higher serum creatinine and lower CRP derive the most benefit from renal artery stenting.

RESUMO

BACKGROUND: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is a simple risk model able to predict early and late mortality after cardiac surgery. Recent data suggest that this score may also predict early clinical outcome after percutaneous coronary intervention (PCI). Data regarding EuroSCORE usefulness to predict late outcome after PCI in unselected patients are lacking. METHODS: EuroSCORE was prospectively assessed in consecutive patients undergoing PCI during 18 months. The primary end-point was cardiac mortality during the follow-up after PCI. Total mortality was the secondary end-point. Kaplan-Meyer analyses were performed dividing the study population in three subgroups according to the additive EuroSCORE algorithm (low risk group: EuroSCORE 0-2; medium risk group: EuroSCORE 3-5; high-risk group: EuroSCORE ≥ 6). Receiver operating characteristics (ROC) curve and landmark analysis on cardiac mortality after 30 days were performed. RESULTS: The study population comprised 1170 patients undergoing PCI. Mean follow-up duration was 633 days (range: 365-1000 days). Cardiac mortality was 2%; 2.4%; 13.2% in patients with low, medium and high EuroSCORE respectively. Kaplan-Meyer survival curves for cardiac death differed significantly between EuroSCORE groups (p<0.0001). The area under the ROC curve for the prediction of cardiac death was 0.77. Similar results were obtained for total mortality. At landmark analysis starting 30 days after PCI, EuroSCORE groups were significantly associated with different survival in the long term (P=0.014). CONCLUSION: EuroSCORE risk model can be efficiently utilized to predict late mortality in consecutive, unselected, patients undergoing PCI.

RESUMO

BACKGROUND: Trans-radial approach (TRA) reduces vascular access-site complications but has some technical limitations. Usually, TRA procedures are performed using 5 Fr or 6 Fr sheaths, whereas complex interventions requiring larger sheaths are approached by trans-femoral access. METHODS: During 4 years, at two Institutions with high TRA use, we have attempted to perform selected complex coronary or peripheral interventions by TRA using sheaths larger than 6 Fr. Clinical and procedural data were prospectively collected. Attempt to place a 7 Fr or 8 Fr sheath (according to the planned strategy of the procedure) was performed after 5-6 Fr sheath insertion, administration of intra-arterial nitrates and radial artery angiography. Late (>3 months) patency of the radial artery was checked (by angiography in the case of repeated procedures or by palpation + reverse Allen test). RESULTS: We collected 60 patients in which TRA large sheath insertion was attempted. The large sheath (87% 7 Fr, 13% 8 Fr) was successfully placed in all cases. Most of the procedures were complex coronary interventions (bifurcated or highly thrombotic or calcific chronic total occlusive lesions), whereas 8.3% were carotid interventions. Procedural success rate was 98.3% (1 failure to reopen a chronic total occlusion). No access-site related complication occurred. In 57 (95%) patients, late radial artery patency was assessed and showed patency in 90% of the cases, the remaining patients having asymptomatic collateralized occlusion. CONCLUSIONS: In selected patients, complex percutaneous interventions requiring 7-8 Fr sheaths can be successfully performed by RA approach without access-site clinical consequences.

RESUMO

OBJECTIVES: This study sought to compare the procedural performance and the acute angiographic result on side-branch ostium obtained using 2 different drug-eluting stents (DES) to treat patients with bifurcated coronary lesions. BACKGROUND: Drug-eluting stents are routinely used in percutaneous coronary interventions (PCI) of bifurcated coronary lesions. Different DES types have major technical differences that may influence the procedural and clinical performance in bifurcation PCI. METHODS: Consecutive patients with bifurcated lesions undergoing DES implantation using a systematic provisional-stenting strategy were randomized to sirolimus-eluting stent (SES) or everolimus-eluting stent (EES) before intervention. The procedural details for PCI were prospectively recorded to assess the occurrence of any trouble in the side-branch (SB) management (primary end point). Post-PCI angiographic result (primary end point: minimal lumen diameter at SB ostium) was evaluated offline by 3-dimensional reconstruction and quantitative coronary analysis. Clinical outcome was prospectively recorded up to 18 months to assess the occurrence of target bifurcation failure. RESULTS: A total of 150 patients were enrolled in the study (29% diabetics, 17% unprotected left main). The stent was successfully implanted according to randomization in all cases. Procedural performance was not significantly different between the 2 kinds of DES. Three-dimensional reconstruction and quantitative coronary analysis showed similar post-PCI results in the main vessel and better results in the SB with EES than with SES (minimal lumen diameter at SB ostium: 1.94 ± 0.72 mm vs. 1.64 ± 0.62 mm; p = 0.013). At 18 months, target bifurcation failure occurred in 7 (9.0%) of SES-treated patients versus 8 (10.7%) of EES patients (p = 0.57). CONCLUSIONS: In patients with bifurcated lesions treated by provisional stenting technique, EES compared with SES is associated with similar procedural performance and better 3-dimensional reconstruction and quantitative coronary analysis result in the SB. Both DES are associated with low rates of major adverse events and angiographic failure.

RESUMO

BACKGROUND: Optimal management of patients needing non-cardiac surgery after coronary stenting has not been established. Objective. To assess the perioperative outcome of patients undergoing non-cardiac surgery after coronary bare-metal stent (BMS) or drug-eluting stent (DES) implantation. METHODS: We enrolled consecutive patients undergoing non-cardiac surgery (up to 2008) after coronary stenting in a single-center registry, prospectively registering clinical and procedural data about revascularization and retrospectively recording surgical details, perioperative therapy and in-hospital outcome after surgery. At our institution, we implant BMS for planned surgery at time of revascularization, and use antiplatelet therapy for surgery required within 1 month of BMS or within 12 months of DES implantation. The primary endpoint was defined as perioperative occurrence of major adverse events, both cardiovascular (death, myocardial infarction, stent thrombosis and repeated revascularization) and hemorrhagic (bleeding requiring transfusions or surgical hemostasis). RESULTS: We enrolled 101 patients: 70 treated with BMS (group 1) and 31 with DES (group 2). The mean interval between stenting and surgery was 288 days. The average number of antiplatelet drugs used during the operative period was higher in group 2 than group 1 (p = 0.02). Fifteen patients (15%) experienced major adverse events (5.9% had non-ST elevation myocardial infarction, 12% received blood transfusions), without a significant difference between the two groups (p = 0.72). At multivariate analysis, the predictor of primary endpoint was time interval between stenting and surgery (p = 0.022). CONCLUSION: We found similar outcomes for non-cardiac surgery after coronary stenting when BMS were selected for planned surgery and dual antiplatelet therapy was used, if indicated, during the operative period.

RESUMO

OBJECTIVES: To investigate the role of renal stenting in selected patients with chronic ischemic heart disease and renal artery stenosis. METHODS: Consecutive patients, with chronic ischemic heart disease and severe hypertension and/or impaired renal function undergoing renal stenting, were prospectively enrolled. Mid-term (at least 2 years) follow-up was performed to assess both changes in renal function [serum creatinine and estimated glomerular filtrate rate (eGFR)] and blood pressure (BP) control (number of required drugs) and to record the incidence of clinical major adverse events. Moreover, in the first consecutive 24 patients, out-of-range pressure values at 24-hr BP monitoring and GFR at renal scintigraphy were measured at baseline and 1 month after stenting. RESULTS: Seventy patients treated by stenting on 86 renal arteries entered the study. Procedural success rate was 99% and no major complication occurred. At 2-year follow-up, both mean serum creatinine (-0.1 +/- 0.7 mg/dl at follow-up compared to baseline, P = 0.6) and eGFR (+3.7 +/- 23.5 ml/min/1.73m(2) at follow-up compared to baseline, P = 0.2) did not significantly change while the number of drugs required to control BP significantly decreased (2.7 +/- 0.8 to 2.2 +/- 0.7, P < 0.0001). In the subset of 24 patients evaluated at 1 month, GFR significantly increased (62 +/- 20 ml/min to 67 +/- 21 ml/min; P = 0.008) and the rate of the out-of-range systolic pressure values at 24-hr monitoring significantly decreased (51-33%, P = 0.005). Elevated baseline creatinine values and the presence of global renal ischemia were identified as predictors of poor outcome at the multivariate analysis. CONCLUSIONS: In selected patients with chronic ischemic heart disease and hypertension and/or renal insufficiency, renal stenting may be performed with very low periprocedural complications and results in unchanged renal function and improved BP control.

RESUMO

OBJECTIVE: To assess the clinical outcome of unselected patients undergoing drug-eluting stent (DES) implantation on bifurcated lesions using a "provisional T And small Protrusion (TAP)" stenting strategy. METHODS: Consecutive patients undergoing DES implantation on one major bifurcation lesion were treated by main-vessel (MV) stenting, followed (if needed) by side-branch (SB) rewiring (with a "pullback" technique) and kissing balloon. SB stenting was performed according to the TAP-technique in selected cases. The endpoint of the study was a 12-month incidence of major adverse cardiac events (MACE) defined as cardiac death, myocardial infarction (MI), stent thrombosis and target vessel revascularization (TVR). RESULTS: The study population included 266 patients (9% unprotected left main). Only 19 patients (7.1%) (with more complex angiographic features) received stents in both the MV and SB using the TAP-technique. Overall, 22 (8.2%) patients had MACE at 1 year. Observed, non-hierarchical MACE were: 1 (0.4%) cardiac death, 11 (4.1%) MI, 2 probable stent thromboses and 12 (4.5%) TVRs. Postprocedural troponin T increase and adverse events up to 12 months were similar between patients treated by MV stenting only or double stenting. CONCLUSIONS: In unselected patients undergoing DES implantation on bifurcated lesions, a provisional TAP-stenting strategy (with a low rate of SB stenting) appears to be safe and effective.

RESUMO

INTRODUCTION AND OBJECTIVES: The Medina bifurcated lesion classification has been widely adopted because of its simplicity. However, no data are available on its use in helping select the best stenting technique for bifurcations. METHODS: Consecutive patients with bifurcated lesions (side branch >or=2.25 mm) were prospectively assessed using the Medina classification. The treatment strategy studied involved implanting two stents in lesions with a Medina classification of 1,1,1 (M3 group) and one stent in only the main vessel in lesions with other Medina classifications (OM group). Clinical endpoints were a major adverse cardiac event (MACE) and target lesion revascularization (TLR) during hospitalization and at 12-month follow-up. RESULTS: The study included 120 patients: 25 in the M3 group and 95 in the OM group. There was no difference in baseline characteristics between the groups. The treatment strategy was successfully implemented in 97% of the OM group and 68% of the M3 group (P< .001). No death or TLR was recorded during hospitalization, though three myocardial infarctions occurred postoperatively (2.1% in the OM group vs 4.0% in the M3 group; P=.6). At 12 months, there was no difference in clinical outcome between the two groups (MACE: 12.6% in the OM group vs 8% in the M3 group; P=.4; TLR: 13.7% in the OM group vs 8% in the M3 group; P=.5). Multivariate analysis showed that bare metal stent implantation (only in patients receiving a single stent) was the only independent predictor of TLR. CONCLUSIONS: The planned treatment strategy of implanting a single stent in patients with bifurcated lesions not classified as Medina 1,1,1 lesions was associated with a very low rate of second stent implantation. Moreover, bare metal stent use was a predictor of TLR, suggesting that drug-eluting stents should be used routinely to treat bifurcated lesions regardless of their angiographic complexity.

RESUMO

BACKGROUND: Transradial access reduces the incidence of access site complications of percutaneous revascularization procedures. However, in patients with peripheral vascular disease, the adoption of transradial approach for superficial femoral artery (SFA) angioplasty is usually prevented by the distance between the vascular access and the target lesions; thus, SFA angioplasty is commonly performed by transfemoral approach. Recently, low-profile balloons with extended shaft length became available, allowing to potentially address SFA lesions by transradial approach. As plain balloon angioplasty represents a valuable option for SFA in-stent restenosis treatment, we evaluated the feasibility of transradial approach in this clinical setting. METHODS: Transradial balloon angioplasty of SFA diffuse in-stent restenosis was attempted in 12 patients aged 69.4 +/- 5.1 years. Six-French 125 cm long MP guiding catheters, 300 cm long 0.018'' guidewire, and low-profile 4 Fr compatible 180 cm long shaft balloons (5 and 6 mm in diameter and 80-150 mm in length) were used. RESULTS: The procedural success was 100%, and no complications occurred during the hospital stay. Compared with a matched group of patients in whom angioplasty was performed by trans-femoral approach, main procedural key data resulted similar except for the amount of administered contrast dye, which was slightly but significantly lower in transradial group (170 +/- 59 ml vs. 241 +/- 103, P = 0.03). CONCLUSIONS: In conclusion, with the currently available equipment, the transradial approach is feasible and represents a valuable alternative for treatment of patients with SFA in-stent restenosis.

RESUMO

BACKGROUND: Subgroup analyses of trials enrolling acute coronary syndrome patients suggest that inhibition of glycoprotein IIb/IIIa can improve the outcome of diabetic patients undergoing percutaneous coronary interventions (PCIs), possibly by improving microvascular perfusion. However, the efficacy of small-molecule IIb/IIIa receptor inhibitors to improve microvascular perfusion in stable diabetic patients undergoing elective PCI has not been specifically investigated. METHODS: We randomized consecutive stable diabetic patients, undergoing elective PCI, to tirofiban or placebo groups along with double antiplatelet therapy. High-dose bolus (25 microg/kg per 3 min) of tirofiban was administered immediately before PCI followed by 8 h continuous infusion (0.15 microg/kg per min). Postprocedural myonecrosis was assessed prospectively by measurement of cardiac troponin T (cTnT) at 6 and 24 h after PCI. The primary end-points were post-PCI coronary flow estimated by corrected thrombolysis in myocardial infarction frame count and post-PCI myocardial infarction. Platelet aggregation was measured by platelet function analyser-100 values. RESULTS: Forty-six patients entered the study (22 randomized to placebo and 24 randomized to tirofiban). The study drug was associated with a significant increase of platelet function analyser-100 values that peaked immediately after PCI and was maintained at 6 h (pre-PCI: 131 +/- 65 s; post-PCI: 222 +/- 49 s; after 6 h: 219 +/- 55 s).Post-PCI corrected thrombolysis in myocardial infarction frame count was similar in tirofiban and in placebo groups (10.2 +/- 3.6 vs. 12.0 +/- 7.6, P = 0.30, respectively). The prevalence of raised cTnT levels was similar in the two groups (25 vs. 30%, P = 0.56, respectively). At multivariate analysis, direct stenting (associated with reduced myonecrosis) and postdilatation (associated with increased myonecrosis) predicted cTnT elevation. CONCLUSION: A high-dose bolus of tirofiban in stable diabetic patients undergoing elective PCI, along with double antiplatelet therapy, was associated with a significant further inhibition of platelet aggregation which, however, did not translate in a lower incidence of post-PCI distal embolization.

RESUMO

OBJECTIVES: To investigate the outcome of patients undergoing percutaneous coronary interventions (PCI) with implantation of a new thin-strut cobalt-chromium bare-metal-stent (BMS) in the drug-eluting-stent (DES) era. BACKGROUND: Despite the contemporary penetration of DES in the clinical practice, a relevant percentage of patients are still treated by BMS. Data on clinical outcome of novel BMSs are lacking. METHODS: This is a single-centre-registry enrolling patients treated by Skylor stent implantation. During the study, the criteria for BMS selection adopted at our institution ("internal" criteria) were as follows: (1) limited compliance to prolonged double antiplatelet therapy, (2) ST-elevation myocardial infarction (STEMI) or saphenous vein grafts (SVG) interventions, and (3) in the absence of these conditions, noncomplex (no bifurcations, no chronic total occlusions) lesions considered at low restenosis risk on the basis of arbitrary angiographic criteria (short lesions, large vessels). Primary and secondary end-points were respectively major adverse cardiovascular events (MACE) and target vessel failure (TVF) up to 9-month. RESULTS: A total of 150 patients were treated with Skylor stent on 169 lesions. At 9-month follow-up, MACE occurred in 12 patients (8.0%) and TVF in 21 lesions (12.4%). By multivariable analysis, the predictors of MACE were Euroscore>or=9 and ejection fraction < 30% while the predictors of TVF were the absence of the angiographic criteria of low restenosis risk and ejection fraction < 30%.
