Fibrinolysis Versus Primary Pci In Stemi Patients Enrolled In The International Survey Of Acute Coronary Syndromes In Transitional Countries

Primary angioplasty has been shown to be more effective than fibrinolysis in terms of mortality and adverse outcomes. More recent data, however, suggests that timely reperfusion with fibrinolysis is comparable to primary angioplasty. The current study gathered data from the International Survey of Acute Coronary Syndromes in Transitional Countries registry. Among 7406 ST-elevation myocardial infarction patients presenting within 12 hours from symptom onset, 6315 underwent primary percutaneous coronary intervention and 1091 were treated with fibrinolysis. The primary outcome was 30-day mortality, while the secondary outcome was a composite of 30-day incidence of death, severe left ventricular dysfunction, stroke or reinfarction. Patients who underwent primary angioplasty tended to have a greater cardiovascular risk profile and were slightly older. On the other hand, patients treated with fibrinolysis received less anti-platelet medications yet were more often prescribed beta blockers in the acute phase. Among those who received fibrinolysis, 43% underwent coronary angiography while 32.3% were treated with a subsequent angioplasty. Total ischemic time was lower in patients undergoing fibrinolysis (185 minutes) than in those treated with primary angioplasty (258 minutes). Rates of primary and secondary combined endpoints were higher in patients receiving fibrinolysis compared to those receiving primary angioplasty (7.8% vs. 4.1%; p<0.0001; OR 1.97, 95% CI, 1.38-2.81; and 14.8% vs. 10.1%, p<0.0001; OR 1.43, 95% CI, 1.12-1.81). When considering only patients receiving reperfusion within 3 hours, regardless of reperfusion strategy, differences in mortality (6.3% vs. 4%, p=0.094, for fibrinolysis or primary angioplasty, respectively; OR 0.87, 95% CI, 0.35-2.16) and in the combined secondary endpoint were no longer observed (12.9% vs 10.8%, p=0.33; OR 0.98, 95% CI, 0.58-1.64), and female sex was no longer a significant predictor of adverse outcomes. When performed 3 hours from symptom onset, fibrinolysis is safe and feasible, in terms of mortality and adverse outcomes, compared to primary angioplasty.

Sex differences in coronary artery disease severity and mortality: the impact of conventional cardiovascular risk factors

It is still unknown whether traditional risk factors may have a sex specific impact on the severity of coronary artery disease (CAD) and subsequent mortality in acute coronary syndromes (ACS). We identified 14 793 patients who underwent coronary angiography for acute coronary syndromes in the ISACS-TC (NCT01218776) registry from 2010 to 2019. The main outcome measure was the association between conventional risk factors and severity of CAD and its relationship with 30-day mortality. Risk ratios (RRs) and 95% CIs were calculated from the ratio of the absolute risks of women versus men using inverse probability of weighting. Severity of disease was categorized as obstructive (≥50% stenosis) versus nonobstructive CAD, specifically Ischemia and No Obstructive Coronary Artery disease (INOCA) and Myocardial Infarction with Non obstructive Coronary Arteries (MINOCA). The RR ratio for obstructive CAD in women versus men among people without diabetes mellitus was 0.49(95%CI,0.41–0.60) and among those with diabetes mellitus was 0.89(95% CI,0.62–1.29), with an interaction by diabetes mellitus status of P =0.002. Exposure to smoking shifted the RR ratios from 0.50 (95% CI, 0.41–0.61) in nonsmokers to 0.75 (95%CI, 0.54–1.03) in current smokers, with an interaction by smoking status of P=0.018. There were no significant sex-related interactions with hypercholesterolemia and hypertension. Women with obstructive CAD had higher 30-day mortality rates than men (RR, 1.75; 95% CI, 1.48–2.07). No sex differences in mortality were observed in patients with INOCA/MINOCA. In conclusion, obstructive CAD in women signifies a higher risk for mortality compared with men. Current smoking and diabetes mellitus disproportionally increase the risk of obstructive CAD in women. Achieving the goal of improving cardiovascular health in women still requires intensive efforts toward further implementation of lifestyle and treatment interventions.

Trattamento transcatetere e chirurgico della stenosi valvolare aortica severa in Hesperia Hospital Modena nella seconda decade del ventunesimo secolo

Scopo Confrontare il trattamento transcatetere (TAVI) balloon-expandable con il trattamento chirurgico di sostituzione valvolare aortica (AVR) della stenosi valvolare aortica severa (SVAS) nella pratica clinica real world. Materiali e metodi Nel decennio 2010-2020, 1486 pazienti con SVAS isolata sono stati sottoposti a AVR (n=1049) o TAVI balloon-expandable (n=437) presso Hesperia Hospital Modena. Sono stati analizzati la Mortality nell’intera popolazione e gli episodi di ricovero cardiovascolare nei 5 anni precedenti e durante il follow-up nella popolazione residente in Emilia Romagna (n=1196) al momento della procedura (AVR n=879, TAVI balloon-expandable n=317). Risultati La popolazione TAVI è risultata mediamente più anziana di quella AVR (età media 82.2 vs. 72.7 anni) e maggiormente gravata da comorbidità. L’In-hospital mortality è stata del 1.4% nella AVR e 2.1% nella TAVI (pNS). La sopravvivenza a 5 anni è stata del 85.74% nella AVR e del 59.45% nella TAVI, con la TAVI come fattore predittivo di All-cause mortality (HR 1.44 95%CI 1.14-1.82). La riospedalizzazione per Heart Failure a 5 anni è stata del 20.6% per AVR e 51.3% per TAVI, con dialisi preoperatoria (HR 5.67 95%CI 3.06-10.49) come principale fattore predittivo. Il tasso di All Stroke a 5 anni è stato del 3.7% nella AVR e del 7.5% nella TAVI, con fibrillazione atriale preoperatoria come principale fattore predittivo (HR 1.91 95%CI 1.06-3.45). Il tasso di angioplastica coronarica percutanea (PCI) a 5 anni è stato del 3.1% sia nella AVR che nella TAVI, con previous PCI come principale fattore predittivo (HR 4.86 95%CI 2.57-9.21). L’impianto di pacemaker a 30 giorni è stato del 2.9% nella AVR e 3.4% nella TAVI (pNS). Conclusioni Nella pratica clinica real-world 2010-2020 di un centro cardiochirurgico a medio volume, la TAVI balloon-expandable ha mostrato una eccellente performance a 30 giorni in confronto con la AVR, che invece ha evidenziato una migliore performance durante follow-up.

Vascular access in patients with peripheral arterial disease undergoing TAVI: the hostile registry

BACKGROUND The optimal access route in patients with severe peripheral artery disease (PAD) undergoing TAVI remains undetermined. OBJECTIVE To compare clinical outcomes with transfemoral access (TFA), transthoracic access (TTA), and non-thoracic alternative access (TAA) in TAVI patients with severe PAD. METHODS Patients with PAD and hostile femoral access (TFA impossible, or possible only after percutaneous treatment) undergoing TAVI at 28 international centers were included in this registry. The primary endpoint was the propensity-adjusted risk of 30-day major adverse events (MAE) defined as the composite of all-cause mortality, stroke/transitory ischemic attack (TIA) or main access site-related VARC 3 major vascular complications. Outcomes were also stratified according to the severity of PAD using a novel risk score (Hostile score). RESULTS Among the 1,707 patients included in the registry, 518 (30.3%) underwent TAVI with TFA after percutaneous treatment, 642 (37.6%) with TTA, and 547 (32.0%) with TAA (mostly transaxillary). Compared with TTA, both TFA (adjusted HR=0.58, 95%CI 0.45-0.75) and TAA (adjusted HR=0.60, 95%CI 0.47-0.78) were associated with lower 30-day rates of MAE, driven by fewer access site-related complications. Composite risks at 1 year were also lower with TFA and TAA compared with TTA. TFA compared with TAA was associated with lower 1-year risks of stroke/TIA (adjusted HR=0.49, 95%CI 0.24-0.98), a finding confined to patients with low Hostile scores (Pinteraction=0.049). CONCLUSIONS Among patients with PAD undergoing TAVI, both TFA and TAA were associated with lower 30-day and 1-year rates of MAE compared with TTA, but 1-year stroke/TIA rates were higher with TAA compared with TFA.

Kissing stenting of aortic bifurcation for aorto-iliac obstructive disease: a comparison between bare metal stents and covered stents

INTRODUCTION Aim of this multicentric study:to compare the short-and mid-term results of bare metal stents(BMS)and covered stents(CS)in the Kissing Stent(KS)technique. METHODS Patients undertaking a KS with BMS or CS between January 2017-August 2021 included. Morphological features of plaques were classified as per the extension of calcifications and thrombosis. Every endpoint and outcome was compared in relation to BMS or CS. All patients included received dual anti-platelets DAPT)for at least one month. RESULTS Thirty-four patients enrolled,17 treated with BMS and 17 with CS. Average age 66 years. The 80% of patients were part of TASC C-D categories. DAPT was administered to 82.4%(28/34)of patients with a mean duration of 4.4±1.6 months. Mean follow-up 32.1±17.8 months. Technical Success was 100%. Immediate Clinical Success was reached in 29 cases(85.3%). Immediate and 30-day Clinical Success was higher in CS(64.7% vs 100%, p=.01). Overall Clinical Success at 1-year follow-up was 91.2%,and resulted significantly higher in CS(82.4% vs 100%,p .04). Overall Primary Patency,Assisted Patency,and Secondary Patency at 30 days were 97.1%,97.1%,and 100%,without differences between BMS and CS(94.1% vs 100%,94.1% vs 100%,and 100% vs 100%;p =.7). Two cases(5.9%)of thrombosis were registered,and both occurred within 3 months after the procedure and both in the BMS,without statistical differences with the CS group(11.8% vs 0%,p .48). Both cases of thrombosis occurred in patients who were not treated with dual antiplatelet therapy(33.3% vs 0%,p .027). Survival statistically differed only at the mean follow-up in favour of CS(70.6% and 100%,p .04). CONCLUSIONS The endovascular approach is currently safe and effective in the treatment of AIOD,and KS offers excellent results in particular if performed with CS; however,no statistically significant differences emerged between the two types of stents in terms of patency,reintervention,and complications. DAPT seems to warrant the best results in terms of patency,although there is still no consensus about the ideal duration of administration.

The frozen elephant trunk technique for the treatment of complex aortic arch and descending thoracic aorta pathologies: long term outcomes and distal reintervention

Background: The frozen elephant trunk(FET) technique is one of the last evolution in the treatment of complex pathologies of the aortic arch and the descending thoracic aorta.Materials and methods: Between January 2007 and March 2021, a total of 396 patients underwent total aortic arch replacements with the FET technique in our centre.The main indications were thoracic aortic aneurysm(n=104,28.2%), chronic aortic dissection(n=224,53.4%) and acute aortic dissection(n=68, 18.4%). We divided the population in two groups according the position of the distal anastomosis (zone 2 vs zone 3) and the length of the stent graft (< 150 mm vs > 150 mm): conservative group (Zone 2 anastomosis + stent length < 150mm, n. 140 pts) and aggressive group (zone 3 anastomosis + stent length > 150mm, n. 141). Results: The overall 30-day mortality rate was 13%(48/369); the risk factor analysis showed that an aggressive approach was neither a risk factor for major complication (permanent dialysis, tracheostomy, bowel malperfusion and permanent paraplegia) neither for 30-day mortality. The survival rate at 1, 5,10 and 15 years was 87.7%,75%,61.3% and 58.4% respectively. During the follow up, an aortic reintervention was performed in 122 patients (38%), 5 patients received a non-aortic cardiac surgery. Freedom from aortic reintervention at 1-,5- and 10-year was 77%,54% and 44% respectively. The freedom from aortic reintervention was higher in the ‘aggressive’ group (62.5%vs40.0% at 5 years, log-rank=0.056). An aggressive approach was not protective for aortic reintervention at follow up and for death at follow up. Conclusions: The FET technique represents a feasible and efficient option in the treatment of complex thoracic aortic pathologies. An aortic reintervention after FET is very common and the decision-making approach should consider and balance the higher risk of an aggressive approach in terms of post-operative complication versus the higher risk of a second aortic reintervention at follow-up.

Nuovi approcci al trattamento della valvulopatia aortica

Background L’incidenza di malattie valvolari aortiche è in costante aumento. La terapia definitiva è chirurgica o interventistica, determinando un evidente miglioramento della qualità di vita, a fronte di un rischio operatorio ormai estremamente basso. Le linee guida internazionali più recenti pongono in classe I entrambe le procedure nella fascia di età fra 65 e 80 anni. Materiali e metodi È stata effettuata un’analisi retrospettiva dei pazienti di età compresa fra 65 e 80 anni, sottoposti a sostituzione valvolare aortica isolata chirurgica con bioprotesi sutureless (gruppo SU-AVR), oppure trans-catetere (gruppo TAVR), presso Maria Cecilia Hospital tra gennaio 2011 e dicembre 2021. Mediante propensity score matching sono stati analizzati, nei due gruppi risultanti, gli outcomes di mortalità e complicanze intraospedaliere, a 30 giorni, ad un anno e attuariale. Risultati Sono stati inclusi nello studio 638 pazienti, di cui 338 (52.98%) nel gruppo SU-AVR e 300 (47.02%) nel gruppo TAVR. Dopo propensity score matching, sono stati ottenuti due gruppi di pazienti (124 per gruppo) senza differenze statisticamente significative nelle comorbidità preoperatorie. La mortalità a 30 giorni è risultata sovrapponibile nei 2 gruppi. Il gruppo TAVR ha mostrato un’incidenza significativamente maggiore di impianto di pacemaker definitivo e di danni vascolari maggiori, mentre il gruppo SU-AVR ha mostrato una maggior incidenza di fibrillazione atriale, di trasfusioni e di insufficienza renale. La mortalità per tutte le cause a un anno è risultata significativamente maggiore per il gruppo TAVR e il divario continua ad aumentare con il tempo. Conclusioni La sostituzione valvolare aortica trans-catetere (TAVR) mostra risultati molto buoni nel breve termine nei pazienti fra 65 e 80 anni di età. Al follow-up a medio termine, tuttavia, i risultati preliminari mostrano un miglior outcome dei pazienti sottoposti a sostituzione valvolare chirurgica, sia in termini di mortalità per qualsiasi causa che di eventi cardiovascolari e cerebrovascolari maggiori.

Traditional risk factors and lifetime risk of acute coronary events

Objective: To investigate the association between the four traditional coronary heart disease (CHD) risk factors (hypertension, smoking, hypercholesterolemia, and diabetes) and outcomes of first ACS. Methods: Data were drawn from the ISACS Archives. The study participants consisted of 70953 patients with first ACS, but without prior CHD. Primary outcomes were patient’ age at hospital presentation and 30-day all-cause mortality. The risk ratios for mortality among subgroups were calculated using a balancing strategy by inverse probability weighting. Trends were evaluated by Pearson's correlation coefficient (r). Results: For fatal ACS (n=6097), exposure to at least one traditional CHD-risk factor ranged from 77.6% in women to 74.5% in men. The presence of all four CHD-risk factors significantly decreased the age at time of ACS event and death by nearly half a decade compared with the absence of any traditional risk factors in both women (from 67.1±12.0 to 61.9±10.3 years; r=-0.089, P<0.001) and men (from 62.8±12.2 to 58.9±9.9 years; r=-0.096, P<0.001). By contrast, there was an inverse association between the number of traditional CHD-risk factors and 30-day mortality. The mortality rates in women ranged from 7.7% with four traditional CHD-risk factors to 16.3% with no traditional risk factors (r=0.073, P<0.001). The corresponding rates in men were 4.8% and 11.5% (r=0.078, P<0.001), respectively. The risk ratios among individuals with at least one CHD-risk factors vs. those with no traditional risk factors were 0.72 (95%CI:0.65-0.79) in women and 0.64 (95%CI:0.59-0.70) in men. This association was consistent among patient subgroups managed with guideline-recommended therapeutic options. Conclusions: The vast majority of patients who die for ACS have traditional CHD-risk factor exposure. Patients with CHD-risk factors die much earlier in life, but they have a lower relative risk of 30-day mortality than those with no traditional CHD-risk factors, even in the context of equitable evidence‐based treatments after hospital admission.

Quantitative evaluation of household nutrition patterns: an econometric assessment of the UK 5-a-day impact on fruit and vegetable consumption

The present work provides an ex-post assessment of the UK 5-a-day information campaign where the positive effects of information on consumption levels are disentangled from the potentially conflicting price dynamics. A model-based estimate of the counterfactual (no-intervention) scenario is computed using data from the Expenditure and Food Survey between 2002 and 2006. For this purpose fruit and vegetable demand is modelled employing Quadratic Almost Ideal Demand System (QUAIDS) specification with demographic effects and controlling for potential endogeneity of prices and total food expenditure.
