Partial-Cost Analysis and Economic Impact of Ambulatory Coronary Angioplasty in a Private Hospital in the Caribbean: Análisis Parcial de Costos e Impacto Económico de la Angioplastia Coronaria Ambulatoria en un Hospital Privado del Caribe.

OBJECTIVES: This study aimed to assess direct costs of percutaneous coronary intervention (PCI) without hospital admission versus PCI with hospital admission longer than 24 hours in a private hospital-institutional perspective in the Dominican Republic in 2022. METHODS: This study has a comparative approach based on a prospective cross-sectional partial-cost analysis. We evaluated the direct costs of 10 patients from PCI without hospital admission approach and 10 patients from a hospital admission longer than 24 hours as a control group. We used a "first-come-first-served" approach from December 2021 to March 2022. The analysis used the electronic invoice generated for each patient. RESULTS: PCI without hospital admission approach represents $472.56 in patient savings, equivalent to a cost reduction of 12.5%. The subcosts analysis showed the pharmacy section as the main driver of the overall cost difference. CONCLUSIONS: PCI without hospital admission was economically cost-saving compared with the control approach in direct costs in the Dominican perspective. The economic benefit is substantial and compliments the ease of use. This analysis may lead to improvements in institutional management of resources and can potentially be adapted to other health systems in the region.

Retrospective Study of 573 Patients with Heart Failure Evaluated for Coronary Artery Disease at Toulouse University Center, France.

BACKGROUND Heart failure (HF) most commonly occurs due to ischemic heart disease from stenotic coronary artery disease (CAD). HF is classified into 3 groups based on the percentage of the ejection fraction (EF): reduced (HFrEF), mid-range (HFmrEF), and preserved (HFpEF). This retrospective study included 573 patients who presented with HF based on the evaluation of EF and were evaluated for CAD by coronary angiography before undergoing coronary angioplasty at a single center in Toulouse, France. MATERIAL AND METHODS This retrospective observational study included patients recently diagnosed with HF or acute decompensation of chronic HF and referred for coronary angiography at Toulouse University Hospital between January 2019 and May 2020. RESULTS Significant CAD was found in 55.8%, 55%, and 55% of the whole population, HFpEF, and HFrEF groups, respectively. Older age, male sex, and diabetes mellitus were the main risk factors for ischemic HF. Except for age and sex, patients with ischemic HFpEF were comparable to those with non-ischemic HFpEF, unlike the ischemic HFrEF group, which had more common cardiovascular risk factors than the non-ischemic HFrEF group. The ischemic HFpEF group had an older age and higher rate of dyslipidemia than the ischemic HFrEF group. CONCLUSIONS At our center, CAD was diagnosed in more than half of patients who presented with heart failure with preserved or reduced EF. Older age and male sex were the common risk factors in patients with HFpEF and HFrEF.

Impact of intravascular ultrasound and final kissing balloon dilatation on long-term clinical outcome in percutaneous revascularization with 1-stent strategy for left main coronary artery stenosis in drug-eluting stent era.

BACKGROUND: It remains uncertain whether intravascular ultrasound (IVUS) use and final kissing balloon (FKB) dilatation would be standard care of percutaneous coronary intervention (PCI) with a simple 1-stent technique in unprotected left main coronary artery (LMCA) stenosis. This study sought to investigate the impact of IVUS use and FKB dilatation on long-term major adverse cardiac events (MACEs) in PCI with a simple 1-stent technique for unprotected LMCA stenosis. METHODS: Between June 2006 and December 2012, 255 patients who underwent PCI with 1 drug-eluting stent for LMCA stenosis were analyzed. Mean follow-up duration was 1663 ± 946 days. Long-term MACEs were defined as death, nonfatal myocardial infarction (MI) and repeat revascularizations. RESULTS: During the follow-up, 72 (28.2%) MACEs occurred including 38 (14.9%) deaths, 21 (8.2%) nonfatal MIs and 13 (5.1%) revascularizations. The IVUS examination and FKB dilatation were done in 158 (62.0%) and 119 (46.7%), respectively. IVUS use (20.3 versus 41.2%; log-rank P < 0.001), not FKB dilatation (30.3 versus 26.5%; log-rank P = 0.614), significantly reduced MACEs. In multivariate analysis, IVUS use was a negative predictor of MACEs [hazards ratio 0.51; 95% confidence interval (CI) 0.29-0.88; P = 0.017], whereas FKB dilatation (hazard ratio 1.68; 95% CI, 1.01-2.80; P = 0.047) was a positive predictor of MACEs. In bifurcation LMCA stenosis, IVUS use (18.7 versus 48.0%; log-rank P < 0.001) significantly reduced MACEs. In nonbifurcation LMCA stenosis, FKB dilatation showed a trend of increased MACEs (P = 0.076). CONCLUSION: IVUS examination is helpful in reducing clinical events in PCI for LMCA bifurcation lesions, whereas mandatory FKB dilatation after the 1-stent technique might be harmful in nonbifurcation LMCA stenosis.

Impact of Coronary Stent Design in Proximal Balloon Edge Dilation Technique for Bifurcation Percutaneous Coronary Intervention.

The proximal optimizing technique (POT) -proximal balloon edge dilation (PBED) sequence for side branch (SB) dilatation with cross-over single-stent implantation decreases both strut obstruction at the SB ostium and stent deformation at the main branch (MB).The purpose of this experimental bench test was to assess the impact of stent design on stent deformation, obstruction by stent struts at a jailed SB ostium, and stent strut malapposition in the POT-PBED sequence.Fractal coronary bifurcation bench models (60- and 80-degree angles) were used, and crossover single-stent implantation (3-link stent: XIENCE Sierra, Abbott Vascular, Santa Clara, CA, n = 10; 2-link stent: Synergy, Boston Scientific, Marlborough, MA, n = 10) was performed from the MB using the POT-PBED sequence. Jailing rates at the SB ostium, stent deformation, and stent strut malapposition of the bifurcation segment were assessed using videoscopy and optical coherence tomography.After SB dilatation using the PBED technique, jailing rates at the SB ostium and stent deformation did not differ significantly between the two types of stents. Conversely, the rate of malapposed struts of the bifurcation segment after the PBED procedure was significantly lower with 3-link stents than with 2-link stents for both 60- and 80-degree angles (60-degree angle: 4.3% ± 4.4% versus 22.0% ± 11.1%, P = 0.044; 80-degree angle: 20.8% ± 15.1% versus 57.2% ± 17.0%, P < 0.001, respectively).In the POT-PBED sequence, 3-link stents might be a preferable coronary bifurcation stent, maintaining a jailed SB ostium while significantly reducing stent strut malapposition of the bifurcation segment when compared with 2-link stents.

Perfil clínico y angiográfico de las mujeres con infarto agudo al miocardio en un hospital nacional / Clinical and angiographic profile of women with acute myocardial infarction in a national hospital

Resumen Justificación: La cardiopatía isquémica es la principal causa de muerte de mujeres en Costa Rica, y su incidencia ha aumentado con los años. A pesar de esto, hay pocos estudios clínicos a este respecto en nuestro país. El objetivo del presente trabajo es presentar las principales características clínicas y angiográficas de un grupo de pacientes con infarto agudo del miocardio con la idea de establecer no solo sus particularidades sino permitir comparaciones con otras poblaciones. Métodos: Se trató de un estudio observacional, descriptivo y retrospectivo, de un periodo de cinco años, en el cual se incluyeron a las pacientes ingresadas con infarto del miocardio a la Unidad de Cuidados Intensivos. Se registraron datos demográficos, de evolución clínica, complicaciones, hallazgos angiográficos, tratamiento y desenlace. El análisis estadístico fue cuantitativo descriptivo, realizado con el programa informático SPSS v.21 (IBM Corp., EEUU) y éste consistió en cálculos de frecuencia, tendencia central, medidas de variabilidad de rango, percentiles, y chi-cuadrado. El protocolo de la investigación fue aprobado por el Comité Ético Científico del Hospital Rafael Ángel Calderón Guardia (DG-3380-2020). Resultados: De 190 pacientes se incluyeron un total de 54. La edad promedio fue de 60 años, con una mortalidad del 17,9%, la cual fue 5,4 % más alta que en los hombres. La mayor parte de las pacientes padecía de hipertensión arterial (74%), 24 (44,5%) eran taba- quistas y 23 (42,5%) tenían diabetes mellitus. Los síntomas más frecuentes fueron: dolor torácico, criodiaforesis y disnea. Se consideró que hubo dolor torácico atípico en 8 casos (15%). A 48 pacientes se le llevó a angioplastia coronaria y solo 35% la recibieron en tiempo oportuno. A 17 pacientes se les aplicó trombólisis farmacológica y solo en 3 pacientes fue exitosa. La arteria coronaria derecha y la arteria descendente anterior fueron los vasos responsables en la mayoría de los casos (19 casos (39,5%) cada uno de ellas.) Conclusión: Esta población tuvo síntomas isquémicos claros, con enfermedad coronaria severa y una mortalidad mayor que los hombres. En general la terapia farmacológica, así como la mecánica se aplicaron en forma tardía.

Abstrac Justification: The ischemic heart disease is the main cause of death of women in Costa Rica, and its incidence has increased with the years. In spite of this, there are few clinical studies in this respect in our country. The aim of this paper is to present the main clinical and angiographic characteristics of a group of patients with acute myocardial infarction in order to establish not only their particularities but also to allow comparisons with other populations. Methods: An observational, descriptive and retrospective study was carried out over a period of five years, in which patients admitted with myocardial infarction to the Intensive Care Unit were included. Demographic data, clinical evolution, complications, angiographic findings, treatment, and outcome were recorded. Statistical analysis was quantitative and descriptive, performed with SPSS v.21 software (IBM Corp., USA) and consisted of calculations of frequency, central tendency, measures of variability, percentiles, and chi-square. The Ethical Committee of the Hospital Rafael Angel Calderon Guardia approved the research protocol (DG-3380-2020). Results: A total of 54 out of 190 patients were included. The average age was 60 years, with a mortality rate of 17.9%, which was 5.4% higher than in men. Most of the patients suffered from arterial hypertension (74%), 24 (44.5%) were smokers and 23 (42.5%) had diabetes mellitus. The most frequent symptoms were chest pain, cryodiaphoresis and dyspnea. It was considered that there was atypical chest pain in 8 cases (15%). Forty-eight patients were taken for coronary angioplasty and only 35% received it in time. Pharmacological thrombolysis was applied to 17 patients, and it was successful in only 3 patients. The right coronary artery and the anterior descending artery were the vessels responsible in most cases (19 cases (39.5%) each). Conclusión: This population had clear ischemic symptoms, with severe coronary disease and higher mortality than men. In general, pharmacological as well as mechanical therapy was applied late.

Statin use and incident cardiovascular events in renal transplant recipients.

BACKGROUND: Statins achieve potent LDL lowering in the general population leading to a significant cardiovascular (CV) risk reduction. In renal transplant recipients (RTR) statins are included in treatment guidelines, however, conclusive evidence of improved cardiovascular outcomes has not been uniformly provided and concerns have been raised about simultaneous use of statins and the immunosuppressant cyclosporine. This study aimed to elucidate the effect of statins on a compound CV endpoint, comprised of ischaemic CV events and CV mortality in RTR, with subgroup analysis focussing on cyclosporine users. METHOD: 622 included RTR (follow-up 5.4 years) were matched based on propensity scores and dichotomized by statin use. Survival analysis was conducted. RESULTS: Cox regression showed that statin use was not significantly associated with the compound CV endpoint in a fully adjusted model (HR = 0.81, 95% CI = 0.53-1.24, P = .33). Subgroup analyses in RTR using cyclosporine revealed a strong positive association of statin use with the CV compound outcome in a fully adjusted model (HR = 6.60, 95% CI 1.75-24.9, P = .005). Furthermore, statin use was positively correlated with cyclosporine trough levels (correlation coefficient 0.11, P = .04). CONCLUSION: In conclusion, statin use does not significantly decrease incident CV events in an overall RTR cohort, but is independently associated with CV-specific mortality and events in cyclosporine using RTR, possibly due to a bilateral pharmacological interaction.

Impact of COVID-19 pandemic on STEMI care: An expanded analysis from the United States.

OBJECTIVE: To evaluate the impact of COVID-19 pandemic migitation measures on of ST-elevation myocardial infarction (STEMI) care. BACKGROUND: We previously reported a 38% decline in cardiac catheterization activations during the early phase of the COVID-19 pandemic mitigation measures. This study extends our early observations using a larger sample of STEMI programs representative of different US regions with the inclusion of more contemporary data. METHODS: Data from 18 hospitals or healthcare systems in the US from January 2019 to April 2020 were collecting including number activations for STEMI, the number of activations leading to angiography and primary percutaneous coronary intervention (PPCI), and average door to balloon (D2B) times. Two periods, January 2019-February 2020 and March-April 2020, were defined to represent periods before (BC) and after (AC) initiation of pandemic mitigation measures, respectively. A generalized estimating equations approach was used to estimate the change in response variables at AC from BC. RESULTS: Compared to BC, the AC period was characterized by a marked reduction in the number of activations for STEMI (29%, 95% CI:18-38, p < .001), number of activations leading to angiography (34%, 95% CI: 12-50, p = .005) and number of activations leading to PPCI (20%, 95% CI: 11-27, p < .001). A decline in STEMI activations drove the reductions in angiography and PPCI volumes. Relative to BC, the D2B times in the AC period increased on average by 20%, 95%CI (-0.2 to 44, p = .05). CONCLUSIONS: The COVID-19 Pandemic has adversely affected many aspects of STEMI care, including timely access to the cardiac catheterization laboratory for PPCI.

Pre-infarction angina is associated with improved prognosis in diabetic patients with ST-elevation myocardial infarction - data from a contemporary cohort.

BACKGROUND: Pre-infarction angina (PIA) is associated with improved prognosis in patients with ST-elevation myocardial infarction (STEMI). Some studies suggest that diabetes may blunt the effect of ischaemic preconditioning. We sought to study the impact of PIA in diabetic patients with STEMI. METHODS: Consecutive patients with STEMI who underwent primary angioplasty were included. PIA was defined as ≥1 episode of chest pain during the week preceding STEMI diagnosis. Incident major adverse cardiovascular events (MACE) were defined as the first occurrence of all-cause death, stroke or acute myocardial infarction. RESULTS: Of the 1143 included patients, 25% were diabetic and 32% had a history of PIA. Diabetic patients with PIA had smaller infarct sizes as estimated by peak creatine kinase (CK) [1144 (500-2212) vs. 1715 (908-3309) U/L, P = 0.003] and peak troponin [3.30 (1.90-6.58) vs. 4.88 (2.50-9.58) ng/ml, P = 0.002], compared to diabetics without PIA. They also had a lower likelihood of evolving with moderate to severe reduced left ventricle ejection fraction (LVEF) (25.6%, n = 22 vs. 46.6%, n = 82, P = 0.001). In non-diabetic patients, PIA was associated with reduced peak CK [1549 (909-2909) vs. 1793 (996-3078), P = 0.0497], but not troponin (3.74 [2.23-7.11] vs. 4.56 [2.44-7.77] ng/ml, P = 0.19), and was not associated with reduced LVEF (32.0%, n = 85 vs. 37.4%, n = 207, P = 0.13). Both diabetic and non-diabetic patients with PIA had a lower likelihood of evolving with a Killip class III/VI (non-diabetic patients: 5.6% vs. 14.1%, P = 0.002; diabetic patients: 12.8% vs. 24.6%, P = 0.049). Over a median follow-up of 18.0 (12.1-25.5) months, PIA was associated with a significant reduction in the incidence of MACE [hazard ratio 0.52, 95% confidence interval (CI) 0.37-0.74, P < 0.001], irrespective of diabetes status. CONCLUSION: PIA is an independent predictor of favourable outcomes in the setting of STEMI for both diabetic and non-diabetic patients.

Impact of Lesion Preparation Technique on Side Branch Compromise in Calcified Coronary Bifurcations: A Subgroup Analysis of the PREPARE-CALC Trial.

OBJECTIVES: To analyze the impact of different techniques of lesion preparation of severely calcified coronary bifurcation lesions. BACKGROUND: The impact of different techniques of lesion preparation of severely calcified coronary bifurcation lesions is poorly investigated. METHODS: We performed an as-treated analysis on 47 calcified bifurcation lesions treated with scoring/cutting balloons (SCB) and 68 lesions treated with rotational atherectomy (RA) in the PREPARE-CALC trial. Compromised side branch (SB) as assessed in the final angiogram was the primary outcome measure and was defined as any significant stenosis, dissection, or thrombolysis in myocardial infarction flow <3. RESULTS: True bifurcation lesions were present in 49% vs. 43% of cases in the SCB and RA groups, respectively. After stent implantation, SB balloon dilatation was necessary in around one-third of cases (36% vs. 38%; p = 0.82), and a two-stent technique was performed in 21.3% vs. 25% (p = 0.75). At the end of the procedure, the SB remained compromised in 15 lesions (32%) in the SCB group and 5 lesions (7%) in the RA group (p = 0.001). Large coronary dissections were more frequently observed in the SCB group (13% vs. 2%; p = 0.02). Postprocedural levels of cardiac biomarkers were significantly higher in patients with a compromised SB at the end of the procedure. CONCLUSIONS: In the PREPARE-CALC trial, side branch compromise was more frequently observed after lesion preparation with SCB as compared with RA. Consequently, in calcified bifurcation lesions, an upfront debulking with an RA-based strategy might optimize the result in the side branch.

Door-to-balloon time in the treatment of ST segment elevation myocardial infarction in a tertiary care center in Saudi Arabia.

BACKGROUND: Atherosclerotic heart disease is still a leading cause of mortality despite improvements in cardiovascular care. Percutaneous coronary intervention (PCI) is the recommended reperfusion therapy in acute ST-elevation myocardial infarction (STEMI), and the international guideline is to achieve a door-to-balloon (D2B) time within 90 minutes of patient arrival to an emergency department (ED). OBJECTIVES: Describe interventions, data for the study period, challenges in ensuring 24/7 patient access to PCI and quality indicators. DESIGN: Retrospective observational study. SETTING: Tertiary care institution in Riyadh, Saudi Arabia. PATIENTS AND METHODS: We included all acute coronary syndrome patients from 2010-2018 who presented or were transferred to our ED from nearby non-PCI capable hospitals, and for whom a 'code heart' was activated. Electronic medical records and the patient care report from the ambulance services were accessed for data collection. MAIN OUTCOME MEASURES: D2B time, readmission and mortality rate. SAMPLE SIZE AND CHARACTERISTICS: 354 patients, mean age (standard deviation) 55.6 (12.6) years, males 84.5% (n=299). RESULTS: STEMI patients constituted 94% (n=334) of the study group; the others had non-STEMI or unstable angina. Hypertension (51%) was the most prevalent risk factor. Coronary artery stenting was the most frequent intervention (77.4%) followed by medical therapy (14.7%). The most common culprit artery was the left anterior descending (52.5%) followed by the right coronary artery (26.0%). A D2B time of within 90 minutes was achieved in over 85% of the patients in four of the years in the 278 patients who underwent PCI. The median D2B time (interquar-tile range) over 2010-2018 was 79 (31) minutes. CONCLUSION: Meeting the international benchmark of D2B time within 90 minutes for STEMI patients is achievable when the main stakeholders collaborate in patient-centric care. Our patient demographics represent regional trends. LIMITATIONS: Patient acceptance to our institution is based upon eligibility criteria. Transfer of 'code heart' patients from other institutions was carried out by our ambulance team. The credentials and experience of cardiologists, emergency physicians, and ambulance services are not standardized across the country. Therefore, the results may not be generalizable to other institutions. CONFLICT OF INTEREST: None.

Direct Stenting Versus Balloon Pre-Dilatation In Elective Percutaneous Coronary Intervention.

BACKGROUND: Stents are now deployed in almost 95% of all percutaneous coronary interventions (PCIs). Recent advances in balloon and stent technology has improved the technique of direct stent (DS) strategy, i.e., stent delivery without pre-dilatation instead of conventional stenting (CS), i.e., stent implantation after balloon pre-dilatation with multiple advantages. METHODS: This randomized controlled trial was conducted at the Cardiology. Department, Punjab Institute of Cardiology, Lahore from April to September, 2017. One hundred patients who were being treated by percutaneous coronary intervention (PCI) were enrolled into two Groups e.g., Group I & group II. 50 patients undergoing direct stenting were enrolled in group I and 50 patients undergoing stenting after balloon pre-dilatation were enrolled in group II after randomization. All patients were treated by single type drug eluting or bare metal stents. Chi square test was used for association and t-test for mean difference between two groups in comparison to post dilatation, fluoroscopy time, procedure time, amount of contrast used, procedural success, side branch compromise, slow flow. The p-value of ˂ 0.05 was significant. RESULTS: This study consisted of 76 males and 24 females out of a total count of 100, with the average age of 52.2±0.01 years. Overall, 43 (43%) patients were diabetic and overall, 44 (44%) were hypertensive. Most of the patients 55 (55%) had PCI to LAD. Average fluoroscopy time 4.l±2.5 minutes in Group I was significantly lesser as compared to 6.7±3.8 minute group II (p-value <0.05). The average procedure time was also marginally lesser in Group I, 23.4±11.6 in comparison to the second Group 33.7±14 (p-value <0.05). Side branch compromise was observed in 10 (20%) in the first group as compared to 8 (16%) the second group. CONCLUSIONS: In comparison to stenting preceded by balloon predilatation, direct stenting is a safer and more feasible procedure with respect to radiation exposure, cost and time duration of the procedure.

[Impact of the COVID-19 pandemic on admissions for acute coronary syndrome: review of the literature and single-center experience]. / Impatto della pandemia COVID-19 sui ricoveri per sindrome coronarica acuta: revisione della letteratura ed esperienza monocentrica.

During the early phase of the lockdown following the COVID-19 pandemic, an alarm on the impact on cardiology admissions for cardiac causes, particularly in the field of acute coronary syndromes (ACS), has emerged. In order to evaluate this trend, we analyzed the literature data published since the beginning of the COVID-19 pandemic to date, in addition to our intensive cardiac care unit (ICCU) experience. This analysis showed (i) a reduction of the overall ICCU admissions up to 50%; (ii) a 40-50% reduction of ACS admissions, greater for non-ST-elevation myocardial infarction (NSTEMI) than for ST-elevation myocardial infarction (STEMI); (iii) a reduction greater than 50% of coronary angiography and percutaneous coronary angioplasty; (iv) a higher time delay of STEMI; and (v) a higher number of ICCU admissions for non-primarily cardiac problems. In conclusion, the lockdown imposed due to the spread of COVID-19 infection has led to a change in the number and type of cardiology admissions. It seems therefore necessary that patients, especially for time-dependent diseases such as ACS, continue to refer to hospital care; that contemporary standard of care for acute cardiac disease should be guaranteed, and that intensivist cardiologists acquire specific skills for the treatment of patients with clinical conditions normally treated by other specialists.

[Partnership development between two hospitals: the integration process of Interventional Cardiology Units between the San Luigi Gonzaga University Hospital and the Local Health Unit Torino 3]. / Lo sviluppo di una partnership tra Aziende Sanitarie: l'integrazione dei laboratori di Emodinamica tra l'Azienda Ospedaliera Universitaria San Luigi Gonzaga di Orbassano e l'Azienda Sanitaria Locale Torino 3.

BACKGROUND: The healthcare sector is among the most complex ones where partnerships and interdependencies between different hospitals can achieve real technical and managerial operational models aimed at optimizing resources. However, the construction of this type of interdependence is not simple to implement, making it necessary to integrate at different organizational and professional levels. The aim of this work is to present the integration process and results achieved during the first 3 years of experience after a synergic integration of the interventional cath lab units of the San Luigi Gonzaga University Hospital, Orbassano and the Infermi Hospital Local Health Unit TO 3, Rivoli. METHODS: Starting from March 2016, data concerning number and type of procedures as well as the distribution of workloads of each operator in the two cath labs were recorded and monitored. Moreover, numbers of urgent procedures performed as well as the door-to-balloon time in case of primary angioplasty were recorded. RESULTS: Compared to the first 12 months of non-integrated activity, the number of procedures remained constant with an overall trend of activity increase (total procedures: +2.6% from 2016 to 2017; +8.7% from 2017 to 2018). No statistically significant differences were found in the average door-to-balloon time, either by stratifying by period (year 2015 vs 2016 vs 2017 vs 2017 vs 2018) or by single institution. All ST-elevation myocardial infarctions were treated at the arrival site, displacing the medical availability team. The mortality rate and the number of complications were not different compared to the trend recorded in previous years. The implementation of joint programs with an exchange of expertise between operators has allowed the rapid development of skills necessary for the execution of structural heart procedures not previously performed in one of the operating centers. CONCLUSIONS: The model of an integrated cath lab unit represents an example of a partnership between two hospitals, which allows a synergistic growth of professional skills, even facing daily logistical challenges. The integration has made it possible to expand the number and type of procedures performed as well to join the on-call equipe without impacting on the door-to-balloon time in case of primary coronary angioplasty.

Cardiologists' and patients' views about the informed consent process and their understanding of the anticipated treatment benefits of coronary angioplasty: A survey study.

BACKGROUND: Percutaneous coronary intervention is a common revascularisation technique. Serious complications are uncommon, but death is one of them. Seeking informed consent in advance of percutaneous coronary intervention is mandatory. Research shows that percutaneous coronary intervention patients have inaccurate perceptions of risks, benefits and alternative treatments. AIM: To assess cardiologists' and patients' views about the informed consent process and anticipated treatment benefits. METHODS: Two cross-sectional, anonymous surveys were distributed in England: an electronic version to a sample of cardiologists and a paper-based version to patients recruited from 10 centres. RESULTS: A sample of 118 cardiologists and 326 patients completed the surveys. Cardiologists and patients shared similar views on the purpose of informed consent; however, over 40% of patients and over a third of cardiologists agreed with statements that patients do not understand, or remember, the information given to them. Patients placed less value than cardiologists on the consent process and over 60% agreed that patients depended on their doctor to make the decision for them. Patients' and cardiologists' views on the benefits of percutaneous coronary intervention were significantly different; notably, 60% of patients mistakenly believed that percutaneous coronary intervention was curative. CONCLUSIONS: The percutaneous coronary intervention informed consent process requires improvement to ensure that patients are more involved and accurately understand treatment benefits to make an informed decision. Redesign of the patient pathway is recommended to allow protected time for health professionals to engage in discussions using evidence-based approaches such as 'teach back' and decision support which improve patient comprehension.

Climate changes and ST-elevation myocardial infarction treated with primary percutaneous coronary angioplasty.

BACKGROUND: The impact of seasonal changes on the incidence of acute myocardial infarction has been incompletely appraised, especially in the modern era of primary percutaneous coronary intervention (PPCI). We aimed to appraise the overall and season-specific impact of climate changes on the daily rate of PCCI. METHODS: Details on PPCI and climate changes were retrospectively collected in three high-volume Italian institutions with different geographical features. The association between rate of PPCI and temperature, atmospheric pressure (ATM), humidity and rainfall was appraised with Poisson models, with overall analyses and according to season of the year. RESULTS: Details on 6880 days with a total of 4132 PPCI were collected. Overall adjusted analysis showed that higher minimum atmospheric pressure 3 days before PPCI were associated with lower risk (regression coefficient = 0.999 [95% confidence interval 0.998-1.000], p = 0.030). Focusing on season, in Winter PPCI rates were increased by lower same day mean temperature (0.973 [0.956-0.990], p = 0.002) and lower rainfall (0.980 [0.960-1.000], p = 0.049). Conversely, in Spring greater changes in atmospheric pressure 3 days before PPCI were associated with increased risk (1.023 [1.002-1.045], p = 0.032), with similar effects in Summer for minimum temperature on the same day (1.022 [1.001-1.044], p = 0.040). CONCLUSIONS: Climate has a significant impact on the risk of PPCI in the current era, with a complex interplay according to season. Higher risk risk is expected with lower minimum atmospheric pressure in the preceding days, lower rainfall in Winter, greater changes in atmospheric pressure in Spring, and higher temperatures in Summer. These findings have important implications for prevention strategies.
