RESUMO

TAVR acute recoil has not been properly assessed with current generation balloon-expandable prosthesis. Acute recoil was greater during initial deployment than in postdilatation, in middle stent than inflow or outflow, and in antero-posterior than lateral axis. No predictors or clinical implications of acute valvular recoil were detected, calling for further research to better understand this phenomenon.

RESUMO

The retrograde approach is needed to increase procedural success in chronic total occlusion angioplasty. This systematic review of the literature demonstrated that retrograde approach is associated with more complex anatomy, worse in-hospital and long-term outcomes. Retrograde approach needs expertise, used judiciously, and major focus in patient safety when performed.

RESUMO

Existen crecientes informes sobre una drástica caída en consultas y realización de procedimientos cardiovasculares (incluyendo urgencias y emergencias) en regiones afectadas por la pandemia de COVID-19, con el consecuente incremento marcado de la mortalidad total que no se explica totalmente por las defunciones atribuidas a COVID-19. En Argentina, la enfermedad cardiovascular lidera el ranking de muertes en adultos con 280 muertes por día, y en las últimas décadas hemos reducido su mortalidad entre 20 y 30% mediante diversas intervenciones basadas en la evidencia. En el presente trabajo realizamos análisis predictivos para entender cuáles podrían ser las consecuencias de una peor implementación de dichas intervenciones. Estimamos que un menor control de los factores de riesgo cardiovascular de abril a octubre de 2020 podría causar hasta 10 500 nuevos casos prevenibles de enfermedad cardiovascular. En términos de infarto de miocardio, una caída del 40% al 60% del tratamiento de reperfusión podría incrementar la mortalidad del 3% al 5%. Un incremento marginal de riesgo relativo de 10% a 15% de muerte cardiovascular equivaldría a un exceso de 6000 a 9000 muertes evitables. En conclusión, dada la alta prevalencia y fatalidad de la enfermedad cardiovascular, incluso un pequeño impacto negativo en la eficacia de su cuidado se traducirá en grandes cantidades de afectados en Argentina. Es necesario informar a las autoridades y educar al público para que sigan controlando enfermedades cardiovasculares y sus factores de riesgo, siempre que existan recursos y minimizando el riesgo de contagio y propagación del virus.


There are increasing reports of a drastic drop in consultations and cardiovascular procedures (including urgencies and emergencies) in regions affected by the COVID-19 pandemic, with a consequent marked increase in total mortality that is not fully explained by COVID-19. Cardiovascular disease leads the ranking in deaths in adults in Argentina with 280 deaths per day, and in recent decades we have reduced its mortality by 20-30% through various evidence-based interventions. Herein we conducted predictive analyses to understand what could be the consequences of a worse implementation of those interventions. We estimate that less control of cardiovascular risk factors from April to October 2020 could cause up to 10 500 new preventable cases of cardiovascular disease. In terms of myocardial infarction, a drop from 40% to 60% of the reperfusion treatment could increase mortality by 3% to 5%. A marginal 10% to 15% increase in relative risk of cardiovascular death would be equivalent to an excess of 6000 to 9000 preventable deaths. In conclusion, given the high prevalence and fatality of cardiovascular disease, even a small negative impact on the efficacy of its care will translate into large numbers of people affected in Argentina. It is necessary to inform the authorities and educate the public so cardiovascular diseases and their risk factors remain a health priority, as long as resources exist and minimizing the risk of contagion and spread of the virus.

RESUMO

OBJECTIVES: To inform about contemporary PCI practice of in-stent (IS) chronic total occlusions (CTO) from a large international registry in Latin America. BACKGROUND: IS-CTO represent a distinctive challenge for PCI, but literature is limited and restricted to high-resource regions of the world. METHODS: Patients undergoing CTO PCI enrolled in the LATAM CTO registry from 42 centers in eight countries were included. We analyzed demographics, angiographic, procedure technique, success and postprocedural outcomes between IS-CTO and non-IS-CTO PCI. RESULTS: From 1,565 patients IS-CTO was present in 181 patients (11.5%). IS-CTO patients had higher prevalence of diabetes and hypertension than patients without IS-CTO. IS-CTOs had less calcification (32.5 vs. 46.7%, p < .001), lower prevalence of a proximal branch (36.3 vs. 50.1%, p < .001), more likely to be ostial (24.4 vs. 18.1%, p = .042), were longer (28.5 vs. 25.2 mm, p = .062), and had less interventional collaterals (49.1 vs. 57.3%, p = .038) compared with non-IS-CTO. CTO complexity scores were similar between both groups. There was no statistically significant difference in the initial or successful strategy between IS-CTO and non-IS-CTO PCI. Technical success rates remained high in IS-CTO (86.7%) and non-IS-CTO (83.1%, p = .230). There was no independent association between IS-CTO and technical success in multivariable analysis. There were no differences between IS-CTO and non-IS-CTO groups for in-hospital clinical outcomes. CONCLUSION: In a contemporary, multicenter, and international registry from Latin America, IS-CTO PCI is frequent and has comparable technical success and safety profile compared to non-IS-CTO PCI.

RESUMO

Limited information is available about the performance of bioabsorbable-polymer drug-eluting stents in the setting of acute myocardial infarction. Patients treated with these stents presenting with acute myocardial infarction are at higher risk of adverse events compared with stable patients. Further clinical trials are needed to fully understand the role of bioabsorbable-polymer drug-eluting stents in patients presenting with acute myocardial infarction.

RESUMO

OBJECTIVES: To report clinical, angiographic characteristics, outcomes, and predictors of unsuccessful procedures in patients who underwent chronic total occlusion (CTO) percutaneous coronary interventions (PCI) in Latin America. BACKGROUND: CTO PCI has been increasingly performed worldwide, but there is a lack of information in this region. METHODS: An international multicenter registry was developed to collect data on CTO PCI performed in centers in Latin America. Patient, angiographic, procedural and outcome data were evaluated. Predictors of unsuccessful procedures were assessed by multivariable analysis. RESULTS: We have included data related to 1,040 CTO PCIs performed in seven countries in Latin America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, and Puerto Rico). The mean age was 64 ± 10 years, and CTO PCI was performed mainly for angina control (81%) or treatment of a large ischemic area (30%). Overall technical success rate was 82.5%, and it was achieved with antegrade wire escalation in 81%, antegrade dissection/re-entry in 8% and with retrograde techniques in 11% of the successful procedures. Multivariable analysis identified moderate/severe calcification, a blunt proximal cap and a previous attempt as independent predictors of unsuccessful procedures. In-hospital major adverse cardiovascular events (MACE) occurred in 3.1% of the cases, death in 1% and cardiac tamponade in 0.9% CONCLUSIONS: CTO PCI in Latin America has been performed mainly for ischemia relief. Procedures were associated with a success rate above 80% and low incidence of MACE. Predictors of unsuccessful procedures were similar to those previously reported in the literature.

RESUMO

Repeat revascularization is a commonly used outcome measure in trials comparing percutaneous coronary intervention and coronary artery bypass graft surgery, and differences in this outcome often drive the relative risk for the primary endpoint. However, repeat revascularization as an outcome measure has important limitations that complicates its meaningful interpretation, including confounding by indication (driven by varying use of stress testing and thresholds for invasive angiography), differential likelihood of revascularization after graft versus stent failure, uncertainty of the prognostic impact of repeat revascularization, and patient preferences and appraisal of the import of repeat revascularization. Knowledge of these issues will result in better appreciation of the utility of repeat revascularization as a clinically meaningful outcome measure. The authors describe these issues and provide recommendations for the use and assessment of repeat revascularization as an endpoint when comparing different revascularization modalities.

RESUMO

BACKGROUND: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions (CBL) remains a challenge in contemporary practice due to the procedural and technical difficulties involved. We sought to review the current evidence on the safety and clinical outcomes of dedicated bifurcation stent (DBS) implantation in comparison with established treatment strategies for CBL-PCI. METHODS: We conducted a comprehensive search to identify randomized control trials (RCTs) reporting 1-year clinical and angiographic outcomes of patients undergoing CBL-PCI with DBS vs conventional CBL-PCI strategies. Random-effects meta-analyses were performed to estimate the effect of DBS compared with conventional CBL-PCI using aggregate data. RESULTS: A total of 5 RCTs comprising 1249 participants met the inclusion criteria. The use of DBS was comparable to conventional stenting techniques in terms of major adverse cardiovascular event (MACE) rate (odds ratio [OR], 1.28; 95% confidence interval [CI], 0.90- 1.82; I²=0%), all-cause mortality (OR, 0.80; 95% CI, 0.31-2.07; I²=0%), cardiac mortality (OR, 0.16; 95% CI, 0.02-1.39; I²=0%), myocardial infarction (OR, 1.26; 95% CI, 0.84-1.89; I²=0%), definite stent thrombosis (OR, 1.75; 95% CI, 0.36-8.52; I²=0%), cumulative target-lesion revascularization (OR, 1.39; 95% CI, 0.85-2.27; I²=0%), clinically driven target-lesion revascularization (OR, 1.23; 95% CI, 0.68-2.22; I²=0%), or target-vessel revascularization (OR, 1.43; 95% CI, 0.92-2.22; I²=0%). CONCLUSION: The present analysis suggests that CBL-PCI with DBS may be associated with similar 1-year clinical and angiographic outcomes compared with conventional CBL-PCI strategies. However, the low quality of evidence and limited follow-up warrant further studies to ascertain any significant differences in patient-important outcomes before the adoption of DBS into routine CBL-PCI practice.

RESUMO

BACKGROUND: Hypertension is the leading cause of cardiovascular disease globally. Despite proven benefits, hypertension control is poor. We hypothesised that a comprehensive approach to lowering blood pressure and other risk factors, informed by detailed analysis of local barriers, would be superior to usual care in individuals with poorly controlled or newly diagnosed hypertension. We tested whether a model of care involving non-physician health workers (NPHWs), primary care physicians, family, and the provision of effective medications, could substantially reduce cardiovascular disease risk. METHODS: HOPE 4 was an open, community-based, cluster-randomised controlled trial involving 1371 individuals with new or poorly controlled hypertension from 30 communities (defined as townships) in Colombia and Malaysia. 16 communities were randomly assigned to control (usual care, n=727), and 14 (n=644) to the intervention. After community screening, the intervention included treatment of cardiovascular disease risk factors by NPHWs using tablet computer-based simplified management algorithms and counselling programmes; free antihypertensive and statin medications recommended by NPHWs but supervised by physicians; and support from a family member or friend (treatment supporter) to improve adherence to medications and healthy behaviours. The primary outcome was the change in Framingham Risk Score 10-year cardiovascular disease risk estimate at 12 months between intervention and control participants. The HOPE 4 trial is registered at ClinicalTrials.gov, NCT01826019. FINDINGS: All communities completed 12-month follow-up (data on 97% of living participants, n=1299). The reduction in Framingham Risk Score for 10-year cardiovascular disease risk was -6·40% (95% CI 8·00 to -4·80) in the control group and -11·17% (-12·88 to -9·47) in the intervention group, with a difference of change of -4·78% (95% CI -7·11 to -2·44, p<0·0001). There was an absolute 11·45 mm Hg (95% CI -14·94 to -7·97) greater reduction in systolic blood pressure, and a 0·41 mmol/L (95% CI -0·60 to -0·23) reduction in LDL with the intervention group (both p<0·0001). Change in blood pressure control status (<140 mm Hg) was 69% in the intervention group versus 30% in the control group (p<0·0001). There were no safety concerns with the intervention. INTERPRETATION: A comprehensive model of care led by NPHWs, involving primary care physicians and family that was informed by local context, substantially improved blood pressure control and cardiovascular disease risk. This strategy is effective, pragmatic, and has the potential to substantially reduce cardiovascular disease compared with current strategies that are typically physician based.

RESUMO

OBJECTIVES: The objective is to describe hypertension (HTN) prevalence, awareness, treatment and control in urban and rural communities in Latin America to inform public and policy-makers. METHODS: Cross-sectional analysis from urban (n = 111) and rural (n = 93) communities including 33 276 participants from six Latin American countries (Argentina, Brazil, Chile, Colombia, Peru and Uruguay)were included. HTN was defined as self-reported HTN on blood pressure (BP)medication or average BP over 140/90 mmHg, awareness as self-reported HTN, and controlled as those with BP under 140/90 mmHg. RESULTS: Mean age was 52 years,60% were Female and 32% belonged to rural communities. HTN prevalence was 44.0%, with the lowest rates in Peru (17.7%) and the highest rates in Brazil (52.5%)58.9% were aware of HTN diagnosis and 53.3% were receiving treatment. Prevalence of HTN were higher in urban (44.8%) than rural (42.1%) communities in all countries. Most participants who were aware of HTN were receiving medical treatment (90.5%), but only 37.6% of patients receiving medical treatment had their BP controlled (<140/<90 mmHg), with the rates being higher in urban (39.6%) than in rural (32.4%) communities. The rate of use of two or more drugs was low [36.4%, lowest in Argentina (29.6%) and highest in Brazil (44.6%)]. Statin use was low (12.3%), especially in rural areas (7.0%). Most modifiable risk factors were higher in people with HTN than people without HTN. CONCLUSION: HTN prevalence is high but BP control is low in Latin America, with marked differences between countries and between urban and rural settings. There is na urgent need for systematic approaches for better detection, treatment optimization and risk factor modification among those with HTN in Latin America.(AU)

RESUMO

Current transradial access (TRA) practices are unknown in the United States and the rest of the world. There is a decline in preprocedure collateral assessment, low use of ultrasound, and infrequent radial patency check after hemostasis. Significant knowledge-practice gaps exist in TRA calling for more dissemination and education.

RESUMO

Background Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status­wealth and education­differ among high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management. Methods In this large-scale prospective cohort study, we recruited adults aged between 35 years and 70 years from 367 urban and 302 rural communities in 20 countries. We collected data on families and households in two questionnaires, and data on cardiovascular risk factors in a third questionnaire, which was supplemented with physical examination. We assessed socioeconomic status using education and a household wealth index. Education was categorized as no or primary school education only, secondary school education, or higher education, defined as completion of trade school, college, or university. Household wealth, calculated at the household level and with household data, was defined by an index on the basis of ownership of assets and housing characteristics. Primary outcomes were major cardiovascular disease (a composite of cardiovascular deaths, strokes, myocardial infarction, and heart failure), cardiovascular mortality, and all-cause mortality. Information on specific events was obtained from participants or their family. (AU)

RESUMO

BACKGROUND: The associations between the extent of forced expiratory volume in 1 s (FEV1) impairment and mortality, incident cardiovascular disease, and respiratory hospitalisations are unclear, and how these associations might vary across populations is unknown. METHODS: In this international, community-based cohort study, we prospectively enrolled adults aged 35-70 years who had no intention of moving residences for 4 years from rural and urban communities across 17 countries. A portable spirometer was used to assess FEV1. FEV1 values were standardised within countries for height, age, and sex, and expressed as a percentage of the country-specific predicted FEV1 value (FEV1%). FEV1% was categorised as no impairment (FEV1% ≥0 SD from country-specific mean), mild impairment (FEV1% <0 SD to -1 SD), moderate impairment (FEV1% <-1 SD to -2 SDs), and severe impairment (FEV1% <-2 SDs [ie, clinically abnormal range]). Follow-up was done every 3 years to collect information on mortality, cardiovascular disease outcomes (including myocardial infarction, stroke, sudden death, or congestive heart failure), and respiratory hospitalisations (from chronic obstructive pulmonary disease, asthma, pneumonia, tuberculosis, or other pulmonary conditions). Fully adjusted hazard ratios (HRs) were calculated by multilevel Cox regression. FINDINGS: Among 126 359 adults with acceptable spirometry data available, during a median 7·8 years (IQR 5·6-9·5) of follow-up, 5488 (4·3%) deaths, 5734 (4·5%) cardiovascular disease events, and 1948 (1·5%) respiratory hospitalisation events occurred. Relative to the no impairment group, mild to severe FEV1% impairments were associated with graded increases in mortality (HR 1·27 [95% CI 1·18-1·36] for mild, 1·74 [1·60-1·90] for moderate, and 2·54 [2·26-2·86] for severe impairment), cardiovascular disease (1·18 [1·10-1·26], 1·39 [1·28-1·51], 2·02 [1·75-2·32]), and respiratory hospitalisation (1·39 [1·24-1·56], 2·02 [1·75-2·32], 2·97 [2·45-3·60]), and this pattern persisted in subgroup analyses considering country income level and various baseline risk factors. Population-attributable risk for mortality (adjusted for age, sex, and country income) from mildly to moderately reduced FEV1% (24·7% [22·2-27·2]) was larger than that from severely reduced FEV1% (3·7% [2·1-5·2]) and from tobacco use (19·7% [17·2-22·3]), previous cardiovascular disease (5·5% [4·5-6·5]), and hypertension (17·1% [14·6-19·6]). Population-attributable risk for cardiovascular disease from mildly to moderately reduced FEV1 was 17·3% (14·8-19·7), second only to the contribution of hypertension (30·1% [27·6-32·5]). INTERPRETATION: FEV1 is an independent and generalisable predictor of mortality, cardiovascular disease, and respiratory hospitalisation, even across the clinically normal range (mild to moderate impairment).

RESUMO

BACKGROUND: Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status-wealth and education-differ among high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management. METHODS: In this large-scale prospective cohort study, we recruited adults aged between 35 years and 70 years from 367 urban and 302 rural communities in 20 countries. We collected data on families and households in two questionnaires, and data on cardiovascular risk factors in a third questionnaire, which was supplemented with physical examination. We assessed socioeconomic status using education and a household wealth index. Education was categorised as no or primary school education only, secondary school education, or higher education, defined as completion of trade school, college, or university. Household wealth, calculated at the household level and with household data, was defined by an index on the basis of ownership of assets and housing characteristics. Primary outcomes were major cardiovascular disease (a composite of cardiovascular deaths, strokes, myocardial infarction, and heart failure), cardiovascular mortality, and all-cause mortality. Information on specific events was obtained from participants or their family. FINDINGS: Recruitment to the study began on Jan 12, 2001, with most participants enrolled between Jan 6, 2005, and Dec 4, 2014. 160 299 (87·9%) of 182 375 participants with baseline data had available follow-up event data and were eligible for inclusion. After exclusion of 6130 (3·8%) participants without complete baseline or follow-up data, 154 169 individuals remained for analysis, from five low-income, 11 middle-income, and four high-income countries. Participants were followed-up for a mean of 7·5 years. Major cardiovascular events were more common among those with low levels of education in all types of country studied, but much more so in low-income countries. After adjustment for wealth and other factors, the HR (low level of education vs high level of education) was 1·23 (95% CI 0·96-1·58) for high-income countries, 1·59 (1·42-1·78) in middle-income countries, and 2·23 (1·79-2·77) in low-income countries (pinteraction<0·0001). We observed similar results for all-cause mortality, with HRs of 1·50 (1·14-1·98) for high-income countries, 1·80 (1·58-2·06) in middle-income countries, and 2·76 (2·29-3·31) in low-income countries (pinteraction<0·0001). By contrast, we found no or weak associations between wealth and these two outcomes. Differences in outcomes between educational groups were not explained by differences in risk factors, which decreased as the level of education increased in high-income countries, but increased as the level of education increased in low-income countries (pinteraction<0·0001). Medical care (eg, management of hypertension, diabetes, and secondary prevention) seemed to play an important part in adverse cardiovascular disease outcomes because such care is likely to be poorer in people with the lowest levels of education compared to those with higher levels of education in low-income countries; however, we observed less marked differences in care based on level of education in middle-income countries and no or minor differences in high-income countries. INTERPRETATION: Although people with a lower level of education in low-income and middle-income countries have higher incidence of and mortality from cardiovascular disease, they have better overall risk factor profiles. However, these individuals have markedly poorer health care. Policies to reduce health inequities globally must include strategies to overcome barriers to care, especially for those with lower levels of education.

RESUMO

This study shows excellent transcatheter aortic valve replacement hemodynamic mid-term durability, aligned with prior research up to 5-years. Long-term (10+ years) data are needed before treating young low-risk people with aortic stenosis. Data so far are excellent, indicating a prosperous future for this procedure in young patients.

RESUMO

There is limited data regarding percutaneous ventricular support in chronic total occlusion angioplasty in terms of population, procedure, and outcomes. This is the largest report to date showing promising results in terms of technical and procedural success in this highly comorbid population. This study encourages more research in the area and its use in large volume and experienced centers.

RESUMO

Transcatheter aortic valve replacement has been used successfully to treat native aortic valve regurgitation. Current observational evidence shows promising results in terms of procedural success while outcome data are difficult to interpret given the observational nature of the evidence. We are ready for a randomized trial, which will be very challenging to run.
