RESUMO
Currently, gender is not considered in the choice of the revascularization strategy for patients with unprotected left main coronary artery (ULMCA) disease. This study analyzed the effect of gender on the outcomes of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) in patients with ULMCA disease. Females who had PCI (n = 328) were compared with females who had CABG (n = 132) and PCI in males (n = 894) was compared with CABG (n = 784). Females with CABG had higher overall hospital mortality and major adverse cardiovascular events (MACE) than females with PCI. Male patients with CABG had higher MACE; however, mortality did not differ between males with CABG vs PCI. In female patients, follow-up mortality was significantly higher in CABG patients, and target lesion revascularization was higher in patients with PCI. Male patients had no difference in mortality and MACE between groups; however, MI was higher with CABG, and congestive heart failure was higher with PCI. In conclusion, women with ULMCA disease treated with PCI could have better survival with lower MACE compared with CABG. These differences were not evident in males treated with either CABG or PCI. PCI could be the preferred revascularization strategy in women with ULMCA disease.

BACKGROUND: The use of dual antiplatelet therapy (DAPT) after coronary revascularization for left-main disease is still debated. The study aimed to characterize patients who received dual versus single antiplatelet therapy (SAPT) after coronary artery bypass grafting (CABG) for unprotected left-main disease and compare the outcomes of those patients. RESULTS: This multicenter retrospective cohort study included 551 patients who were grouped into 2 groups: patients who received SAPT (n = 150) and those who received DAPT (n = 401). There were no differences in age ( P = 0.451), gender ( P = 0.063), smoking ( P = 0.941), diabetes mellitus ( P = 0.773), history of myocardial infarction ( P = 0.709), chronic kidney disease ( P = 0.615), atrial fibrillation ( P = 0.306), or cerebrovascular accident ( P = 0.550) between patients who received SAPT versus DAPT. DAPTs were more commonly used in patients with acute coronary syndrome [87 (58%) vs. 273 (68.08%); P = 0.027], after off-pump CABG [12 (8%) vs. 73 (18.2%); P = 0.003] and in patients with radial artery grafts [1 (0.67%) vs. 32 (7.98%); P < 0.001]. While SAPTs were more commonly used in patients with low ejection fraction [55 (36.67%) vs. 61 (15.21%); P < 0.001] and in patients with postoperative acute kidney injury [27 (18%) vs. 37 (9.23%); P = 0.004]. The attributed treatment effect of DAPT for follow-up major adverse cerebrovascular and cardiac events was not significantly different from that of SAPT [ß, -2.08 (95% confidence interval (CI), -20.8-16.7); P = 0.828]. The attributed treatment effect of DAPT on follow-up all-cause mortality was not significantly different from that of SAPT [ß, 4.12 (CI, -11.1-19.32); P = 0.595]. There was no difference in bleeding between groups ( P = 0.666). CONCLUSIONS: DAPTs were more commonly used in patients with acute coronary syndrome, after off-pump CABG, and with radial artery grafts. SAPTs were more commonly used in patients with low ejection fraction and acute kidney injury. Patients on DAPT after CABG for left-main disease had comparable major adverse cerebrovascular and cardiac events and survival to patients on SAPT, with no difference in bleeding events.

BACKGROUND: Continuous automatic optimisation of cardiac resynchronisation therapy (CRT), stimulating only the left ventricle to fuse with intrinsic right bundle conduction (synchronised left ventricular stimulation), might offer better outcomes than conventional CRT in patients with heart failure, left bundle branch block, and normal atrioventricular conduction. This study aimed to compare clinical outcomes of adaptive CRT versus conventional CRT in patients with heart failure with intact atrioventricular conduction and left bundle branch block. METHODS: This global, prospective, randomised controlled trial was done in 227 hospitals in 27 countries across Asia, Australia, Europe, and North America. Eligible patients were aged 18 years or older with class 2-4 heart failure, an ejection fraction of 35% or less, left bundle branch block with QRS duration of 140 ms or more (male patients) or 130 ms or more (female patients), and a baseline PR interval 200 ms or less. Patients were randomly assigned (1:1) via block permutation to adaptive CRT (an algorithm providing synchronised left ventricular stimulation) or conventional biventricular CRT using a device programmer. All patients received device programming but were masked until procedures were completed. Site staff were not masked to group assignment. The primary outcome was a composite of all-cause death or intervention for heart failure decompensation and was assessed in the intention-to-treat population. Safety events were collected and reported in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT02205359, and is closed to accrual. FINDINGS: Between Aug 5, 2014, and Jan 31, 2019, of 3797 patients enrolled, 3617 (95·3%) were randomly assigned (1810 to adaptive CRT and 1807 to conventional CRT). The futility boundary was crossed at the third interim analysis on June 23, 2022, when the decision was made to stop the trial early. 1568 (43·4%) of 3617 patients were female and 2049 (56·6%) were male. Median follow-up was 59·0 months (IQR 45-72). A primary outcome event occurred in 430 of 1810 patients (Kaplan-Meier occurrence rate 23·5% [95% CI 21·3-25·5] at 60 months) in the adaptive CRT group and in 470 of 1807 patients (25·7% [23·5-27·8] at 60 months) in the conventional CRT group (hazard ratio 0·89, 95% CI 0·78-1·01; p=0·077). System-related adverse events were reported in 452 (25·0%) of 1810 patients in the adaptive CRT group and 440 (24·3%) of 1807 patients in the conventional CRT group. INTERPRETATION: Compared with conventional CRT, adaptive CRT did not significantly reduce the incidence of all-cause death or intervention for heart failure decompensation in the included population of patients with heart failure, left bundle branch block, and intact AV conduction. Death and heart failure decompensation rates were low with both CRT therapies, suggesting a greater response to CRT occurred in this population than in patients in previous trials. FUNDING: Medtronic.

BACKGROUND: The optimal revascularization strategy in patients with left main coronary artery (LMCA) disease in the emergency setting is still controversial. Thus, we aimed to compare the outcomes of percutaneous coronary interventions (PCI) vs. coronary artery bypass grafting (CABG) in patients with and without emergent LMCA disease. METHODS: This retrospective cohort study included 2138 patients recruited from 14 centers between 2015 and 2019. We compared patients with emergent LMCA revascularization who underwent PCI (n = 264) to patients who underwent CABG (n = 196) and patients with non-emergent LMCA revascularization with PCI (n = 958) to those who underwent CABG (n = 720). The study outcomes were in-hospital and follow-up all-cause mortality and major adverse cardiovascular and cerebrovascular events (MACCE). RESULTS: Emergency PCI patients were older and had a significantly higher prevalence of chronic kidney disease, lower ejection fraction, and higher EuroSCORE than CABG patients. CABG patients had significantly higher SYNTAX scores, multivessel disease, and ostial lesions. In patients presenting with arrest, PCI had significantly lower MACCE (P = 0.017) and in-hospital mortality (P = 0.016) than CABG. In non-emergent revascularization, PCI was associated with lower MACCE in patients with low (P = 0.015) and intermediate (P < 0.001) EuroSCORE. PCI was associated with lower MACCE in patients with low (P = 0.002) and intermediate (P = 0.008) SYNTAX scores. In non-emergent revascularization, PCI was associated with reduced hospital mortality in patients with intermediate (P = 0.001) and high (P = 0.002) EuroSCORE compared to CABG. PCI was associated with lower hospital mortality in patients with low (P = 0.031) and intermediate (P = 0.001) SYNTAX scores. At a median follow-up time of 20 months (IQR: 10-37), emergency PCI had lower MACCE compared to CABG [HR: 0.30 (95% CI 0.14-0.66), P < 0.003], with no significant difference in all-cause mortality between emergency PCI and CABG [HR: 1.18 (95% CI 0.23-6.08), P = 0.845]. CONCLUSIONS: PCI could be advantageous over CABG in revascularizing LMCA disease in emergencies. PCI could be preferred for revascularization of non-emergent LMCA in patients with intermediate EuroSCORE and low and intermediate SYNTAX scores.

INTRODUCTION: The evidence about the optimal revascularization strategy in patients with left main coronary artery (LMCA) disease and impaired renal function is limited. Thus, we aimed to compare the outcomes of LMCA disease revascularization (percutaneous coronary intervention [PCI] vs. coronary artery bypass grafting [CABG]) in patients with and without impaired renal function. METHODS: This retrospective cohort study included 2,138 patients recruited from 14 centers between 2015 and 2,019. We compared patients with impaired renal function who had PCI (n= 316) to those who had CABG (n = 121) and compared patients with normal renal function who had PCI (n = 906) to those who had CABG (n = 795). The study outcomes were in-hospital and follow-up major adverse cardiovascular and cerebrovascular events (MACCE). RESULTS: Multivariable logistic regression analysis showed that the risk of in-hospital MACCE was significantly higher in CABG compared to PCI in patients with impaired renal function (odds ratio [OR]: 8.13 [95% CI: 4.19-15.76], p < 0.001) and normal renal function (OR: 2.59 [95% CI: 1.79-3.73]; p < 0.001). There were no differences in follow-up MACCE between CABG and PCI in patients with impaired renal function (HR: 1.14 [95% CI: 0.71-1.81], p = 0.585) and normal renal function (HR: 1.12 [0.90-1.39], p = 0.312). CONCLUSIONS: PCI could have an advantage over CABG in revascularization of LMCA disease in patients with impaired renal function regarding in-hospital MACCE. The follow-up MACCE was comparable between PCI and CABG in patients with impaired and normal renal function.

BACKGROUND: Real-world data for managing patients with diabetes and left main coronary artery (LMCA) disease are scarce. We compared percutaneous coronary intervention (PCI) outcomes versus coronary artery bypass grafting (CABG) in diabetes and LMCA disease patients. METHODS: We retrospectively studied patients with LMCA presented to 14 centers from 2015 to 2019. The study included 2138 patients with unprotected LMCA disease; 1468 (68.7 %) had diabetes. Patients were grouped into; diabetes with PCI (n = 804) or CABG (n = 664) and non-diabetes with PCI (n = 418) or CABG (n = 252). RESULTS: In diabetes, cardiac (34 (5.1 %) vs. 22 (2.7 %); P = 0.016), non-cardiac (13 (2 %) vs. 6 (0.7 %); P = 0.027) and total hospital mortality (47 (7.1 %) vs. 28 (3.5 %); P = 0.0019), myocardial infarction (45 (6.8 %) vs. 11 (1.4 %); P = 0.001), cerebrovascular events (25 (3.8 %) vs. 12 (1.5 %); P = 0.005) and minor bleeding (65 (9.8 %) vs. 50 (6.2 %); P = 0.006) were significantly higher in CABG patients compared to PCI; respectively. The median follow-up time was 20 (10-37) months. In diabetes, total mortality was higher in CABG (P = 0.001) while congestive heart failure was higher in PCI (P = 0.001). There were no differences in major adverse cerebrovascular events and target lesion revascularization between PCI and CABG. Predictors of mortality in diabetes were high anatomical SYNTAX, peripheral arterial disease, chronic kidney disease, and cardiogenic shock. CONCLUSIONS: In this multicenter retrospective study, we found no significant difference in clinical outcomes during the short-term follow-up between PCI with second-generation DES and CABG except for lower total mortality and a higher rate of congestive heart failure in PCI group of patients. Randomized trials to characterize patients who could benefit from each treatment option are needed.

AIMS: The impact of left ventricular dysfunction on clinical outcomes following revascularization is not well established in patients with unprotected left main coronary artery disease (ULMCA). In this study, we evaluated the impact of left ventricular ejection fraction (LVEF) on clinical outcomes of patients with ULMCA requiring revascularization with percutaneous coronary intervention (PCI) compared with coronary artery bypass graft (CABG). METHODS: The details of the design, methods, end points, and relevant definitions are outlined in the Gulf Left Main Registry: a retrospective, observational study conducted between January 2015 and December 2019 across 14 centres in 3 Gulf countries. In this study, the data on patients with ULMCA who underwent revascularization through PCI or CABG were stratified by LVEF into three main subgroups; low (l-LVEF <40%), mid-range (m-LVEF 40-49%), and preserved (p-LVEF ≥50%). Primary outcomes were hospital major adverse cardiovascular and cerebrovascular events (MACCE) and mortality and follow-up MACCE and mortality. RESULTS: A total of 2137 patients were included; 1221 underwent PCI and 916 had CABG. During hospitalization, MACCE was significantly higher in patients with l-LVEF [(10.10%), P = 0.005] and m-LVEF [(10.80%), P = 0.009], whereas total mortality was higher in patients with m-LVEF [(7.40%), P = 0.009] and p-LVEF [(7.10%), P = 0.045] who underwent CABG. There was no mortality difference between groups in patients with l-LVEF. At a median follow-up of 15 months, there was no difference in MACCE and total mortality between patients who underwent CABG or PCI with p-LVEF and m-LVEF. CONCLUSION: CABG was associated with higher in-hospital events. Hospital mortality in patients with l-LVEF was comparable between CABG and PCI. At 15 months' follow-up, PCI could have an advantage in decreasing MACCE in patients with l-LVEF.

Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in revascularization of left main coronary artery (LMCA) disease has been evaluated in previous studies. However, there has been minimal study of the relationship between co-existing non-coronary atherosclerosis (NCA) and LMCA disease revascularization. We aim to examine this relationship. The Gulf-LM study is a retrospective analysis of unprotected LMCA revascularization cases undergoing PCI with second generation drug-eluting stent vs CABG across 14 centers within 3 Gulf countries between January 2015 and December 2019. A total of 2138 patients were included, 381 with coexisting NCA and 1757 without. Outcomes examined included major adverse cardiovascular and cerebrovascular events (MACCE), cardiac and non-cardiac death, and all bleeding. In patients with NCA, preexisting myocardial infarction and congestive heart failure were more common, with PCI being the most common revascularization strategy. A statistically significant reduction in in-hospital MACCE and all bleeding was noted in patients with NCA undergoing PCI as compared to CABG. At a median follow-up of 15 months, MACCE and major bleeding outcomes continued to favor the PCI group, though no such difference was identified between revascularization strategies in patients without NCA.In this multicenter retrospective study of patients with and without NCA who require revascularization (PCI and CABG) for unprotected LMCA disease, PCI demonstrated a better clinical outcome in MACCE both in-hospital and during the short-term follow-up in patients with NCA. However, no such difference was observed in patients without NCA.

The optimal stenting strategy for unprotected left main coronary artery (ULMCA) disease remains debated. This retrospective observational study (Gulf Left Main Registry) analyzed the outcomes of 1 vs 2 stents in patients with unprotected left main percutaneous coronary intervention (PCI). Overall, 1222 patients were evaluated; 173 had 1 stent and 1049 had 2 stents. The 2-stent group was older with more comorbidities, higher mean SYNTAX scores, and more distal bifurcation lesions. In the 1-stent group, in-hospital events were significant for major bleeding, and better mean creatinine clearance. At median follow-up of 20 months, the 1-stent group was more likely to have target lesion revascularization (TLR). Total mortality was numerically lower in the 1-stent group (.00% vs 2.10%); however, this was not statistically significant (P=.068). Our analysis demonstrates the benefits of a 2-stent approach for ULMCA patients with high SYNTAX scores and lesions in both major side branches, while the potential benefit of a 1-stent approach for less complex ULMCA was also observed. Further studies with longer follow-up are needed to definitively demonstrate the optimal approach.

Background: E-government platforms provide an opportunity to use a novel data source for population health surveillance (also known as e-health). Absher is a Saudi e-government platform with 23 million authenticated users, including residents and citizens in Saudi Arabia. All Absher users were invited to participate in a web-based survey to estimate the prevalence of noncommunicable diseases and their risk factors in Saudi Arabia. Objective: To assess the potential of using an e-government platform (Absher) to administer web-based health surveys. Methods: A cross-sectional, web-based health survey was administered to Absher users between April 2019 and March 2020. The survey instrument included eight items and took <5 min to complete. The respondents' data were compared to Saudi Arabia's 2016 census. Descriptive summary statistics of the prevalence of major noncommuncable diseases are presented and compared to population-based prevalence data from Saudi Arabia's World Health Survey (WHS) 2019. All analysis was conducted using Stata 13.0. Results: Overall, the Absher health survey had a 24.6% response rate, with most respondents being male (84%), Saudi (67%), and between 30 and 44 years of age (49%). Overall, the prevalence of noncommunicable diseases and risk factors among respondents was high for overweight (35%) and obesity (30%) and low for asthma (6%). The prevalence of diabetes, dyslipidemia, and hypertension was between 15 and 17% on average, and 26.5% were smokers. In comparison to population-based World Health Survey estimates, the Absher survey overestimated obesity, diabetes, dyslipidemia, hypertension, and smoking rates, and underestimated overweight, whereas asthma prevalence was similar for Absher and the WHS. Conclusions: With improvements in the study design, the use of e-government platforms can provide a useful and potentially low-cost data source for public health research.

Coronary artery bypass surgery (CABG) has been the standard of care for revascularization for patients with obstructive unprotected left main coronary disease (ULMCA). There have been multiple randomized and registry data demonstrating the technical and clinical efficacy of PCI in certain patients with ULMCA. The purpose of this study is to evaluate clinical outcomes of ULMCA PCI as compared to CABG in patients requiring revascularization in three Gulf countries. All ULMCA cases treated by PCI with DES versus CABG were retrospectively identified from 14 centers in 3 Arab Gulf countries (KSA, UAE, and Bahrain) from January 2015 to December 2019. In total, 2138 patients were included: 1222 were treated with PCI versus 916 with CABG. Patients undergoing PCI were older, and had higher comorbidities and mean European System for Cardiac Operative Risk Evaluation (EuroSCORE). Aborted cardiac arrest and cardiogenic shock were reported more in the PCI group at hospital presentation. In addition, lower ejection fractions were reported in the PCI group. In hospital mortality and major adverse cardiovascular and cerebrovascular events (MACCE) occurred more in patients undergoing CABG than PCI. At median follow-up of 15 months (interquartile range, 30), no difference was observed in freedom from revascularization, MACCE, or total mortality between those treated with PCI and CABG. While findings are similar to Western data registries, continued follow-up will be needed to ascertain whether this pattern continues into latter years.

BACKGROUND: Most sudden cardiac arrests occur at home, with low rates of bystander cardiopulmonary resuscitation being performed. We aimed to assess knowledge of cardiopulmonary resuscitation among individuals in Riyadh City, Saudi Arabia, who are not involved in health care. METHODS: A community-based cross-sectional study was conducted between January and February 2020 in 4 different areas in Riyadh City: North, South, East, and West. The participants were surveyed using a validated self-administered questionnaire. The Statistical Package for Social Sciences version 25.0 was used for inferential statistics and binary logistic regression analysis. RESULTS: A total of 856 participants completed the questionnaire, 51.8% were unaware of cardiopulmonary resuscitation. Only 4.4% of the participants had attended a formal cardiopulmonary resuscitation training course, 5.1% were campaign attendees, and 38.7% acquired their experience through the media. Having a higher level of education was positively associated with having knowledge of cardiopulmonary resuscitation. The main concern among attendees of cardiopulmonary resuscitation training courses and campaigns was legal issues, whereas inadequate knowledge was the major barrier for those who had learned about cardiopulmonary resuscitation through the media. CONCLUSION: The level of knowledge of cardiopulmonary resuscitation among non-health care individuals in Riyadh City was found to be insufficient. Therefore, coordinated efforts among different authorities should be considered to implement a structured strategy aiming to increase awareness and knowledge of cardiopulmonary resuscitation among non-health care individuals.
RESUMO
Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome and sudden cardiac death. The triggers for SCAD often do not include traditional atherosclerotic risk factors. The most commonly reported triggers are extreme physical or emotional stress. The current study compared in-hospital and follow-up events in patients with SCAD with and without reported stress. Data from 83 patients with a confirmed diagnosis of SCAD were collected retrospectively from 30 centers in 4 Arab Gulf countries (KSA, UAE, Kuwait, and Bahrain) from January 2011 to December 2017. In-hospital myocardial infarction (MI), percutaneous coronary intervention (PCI), ventricular tachycardia/ventricular fibrillation, cardiogenic shock, death, ICD placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) events were compared between those with and without reported stress. Emotional and physical stress was defined as new or unusually intense stress, within 1 week of their initial hospitalization. The median age of patients in the study was 44 (37-55) years. Foty-two (51%) were women. Stress (emotional, physical, and combined) was reported in 49 (59%) of all patients. Sixty-two percent of women with SCAD reported stress, and 51 % of men with SCAD reported stress. Men more commonly reported physical and combined stress. Women more commonly reported emotional stress (P < 0.001). The presence or absence of reported stress did not impact on overall adverse cardiovascular events (Pâ¯=â¯0.8). In-hospital and follow-up events were comparable in patients with SCAD in the presence or absence of reported stress as a trigger.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome (ACS) and sudden cardiac death. Physical or emotional stressors are the most commonly reported triggers for SCAD. Unemployment has been identified as a source of emotional stress and is linked to poor mental and physical health. OBJECTIVE: To examine the association between employment status and in-hospital and follow-up adverse cardiovascular events in patients with SCAD. METHODS: We conducted a retrospective, multi-center, observational study of patients undergoing coronary angiography for ACS between January 2011 and December 2017. The total number of patients enrolled was 198,000. Patients were diagnosed with SCAD based on angiographic and intravascular imaging modalities whenever available. There were 83 patients identified with SCAD from 30 medical centers in 4 Arab gulf countries. In-hospital (myocardial infarction, percutaneous intervention, ventricular tachycardia/ventricular fibrillation, cardiogenic shock, death, internal cardioverter/ defibrillator placement, dissection extension) and follow-up (myocardial infarction, de novo SCAD, death, spontaneous superior mesenteric artery dissection) cardiac events were compared among those who were employed and those who were not. RESULTS: The median age of patients in the study was 44 (37- 55) years. There were 42 (50.6%) female patients, and 41 (49.4) male patients. Of the cohort, 50 (60%) of the patients were employed and the remaining 33 (40%) were unemployed. 66% of all men were employed and 76% of all women were unemployed. After adjusting for gender unemployment was associated with worse in- -hospital and follow-up cardiac events (adjusted OR 7.1, [1.3, 37.9]), p = 0.021. CONCLUSION: Adverse cardiovascular events were significantly worse for patients with SCAD who were unemployed.

The COVID-19 pandemic had significant impact on health care worldwide which has led to a reduction in all elective admissions and management of patients through virtual care. The purpose of this study is to assess changes in STEMI volumes, door to reperfusion, and the time from the onset of symptoms until reperfusion therapy, and in-hospital events between the pre-COVID-19 (PC) and after COVID-19 (AC) period. All acute ST-segment elevation myocardial infarction (STEMI) cases were retrospectively identified from 16 centers in the Kingdom of Saudi Arabia during the COVID-19 period from January 01 to April 30, 2020. These cases were compared to a pre-COVID period from January 01 to April 30, 2018 and 2019. One thousand seven hundred and eighty-five patients with a mean age 56.3 (SD ± 12.4) years, 88.3% were male. During COVID-19 Pandemic the total STEMI volumes was reduced (28%, nâ¯=â¯500), STEMI volumes for those treated with reperfusion therapy was reduced too (27.6%, n= 450). Door to balloon time < 90 minutes was achieved in (73.1%, noâ¯=â¯307) during 2020. Timing from the onset of symptoms to the balloon of more than 12 hours was higher during 2020 comparing to pre-COVID 19 years (17.2% vs <3%, respectively). There were no differences between the AC and PC period with respect to in-hospital events and the length of hospital stay. There was a reduction in the STEMI volumes during 2020. Our data reflected the standard of care for STEMI patients continued during the COVID-19 pandemic while demonstrating patients delayed presenting to the hospital.

BACKGROUND: Atherosclerotic coronary plaque dissection (ACPD) is one cause of acute coronary syndrome (ACS) caused by underlying atherosclerosis. Spontaneous coronary artery dissection (SCAD) occurs outside the setting of atherosclerosis among young women and individuals with few or no conventional atherosclerotic risk factors, and has emerged as an important cause of ACS, and sudden death. A comparison between ACPD and SCAD has not been previously addressed in the literature. Our study will compare ACPD and SCAD. METHODS: Patients with confirmed diagnosis of SCAD and ACPD were retrospectively identified from 30 centers in 4 Arab Gulf countries between January 2011 and December 2017. In-hospital (ventricular tachycardia/ventricular fibrillation, myocardial infarction (MI), percutaneous coronary intervention, dissection extension, cardiogenic shock, death, implantable cardioverter-defibrillator placement) and follow-up (MI, de novo SCAD, spontaneous superior mesenteric artery dissection, death) events were compared between them. RESULTS: Eighty-three cases of SCAD and 48 ACPD were compared. ACPD patients were more frequently male (91.67% vs. 49.40%, P < 0.001) and older (58.5 vs. 44, P < 0.001). Cardiovascular risk factors were more prevalent in patients with ACPD, including diabetes mellitus (60.4% vs. 25.3%), dyslipidemia (62.5% vs. 38.5%), and hypertension (62.5% vs. 31.3%), P < 0.001. Hospital presentation of ST-elevation MI was diagnosed in 48% of SCAD versus 27% of ACPD patients (P = 0.012). SCAD patients received medical-only treatment in 40% of cases and ACPD in 21% (P = 0.042). In-hospital and follow-up events were comparable in both groups (P = 0.25). CONCLUSIONS: Despite a completely different pathophysiology of ACS between SCAD and ACPD, in-hospital and follow-up events were comparable.

AIMS: Although cardiac resynchronization therapy (CRT) has proven beneficial in several randomized trials, a subset of patients have limited clinical improvement. The AdaptivCRT algorithm provides automated selection between synchronized left ventricular or biventricular pacing with optimization of atrioventricular delays. The rationale and design of the economic analysis of the AdaptResponse clinical trial are described. RATIONALE: The costs associated with HF hospitalization are substantial and are compounded by a high rate of readmission. HF hospitalization payments range from $1,001 for Greece to $12,235 for US private insurance. When examining the breakdown of HF-related costs, it is clear that approximately 55% of the hospitalization costs are directly attributable to length of stay. Notably, the mean costs of a CRT patient in need of a HF-related hospitalization are currently estimated to be an average of $10,679. METHODS: The economic analysis of the AdaptResponse trial has two main objectives. The hospital provider objective seeks to test the hypothesis that AdaptivCRT reduces the incidence of all-cause re-admissions after a heart failure admission within 30 days of the index event. A negative binomial regression model will be used to estimate and compare the number of readmissions after an index HF hospitalization. The payer economic objective will assess cost-effectiveness of CRT devices with the AdaptivCRT algorithm relative to traditional CRT programming. This analysis will be conducted from a U.S. payer perspective. A decision analytic model comprised of a 6-month decision tree and a Markov model for long term extrapolation will be used to evaluate lifetime costs and benefits. CONCLUSION: AdaptivCRT may offer improvements over traditional device programming in patient outcomes. How the data from AdaptResponse will be used to demonstrate if these clinical benefits translate into substantial economic gains is herein described.

AIMS: Response to cardiac resynchronization therapy (CRT) is known to be associated with a number of clinical characteristics, including QRS duration and morphology, gender, height, and the aetiology of heart failure (HF). We assessed the relation of gender and baseline characteristics with QRS duration and Kansas City Cardiomyopathy Questionnaire. METHODS AND RESULTS: AdaptResponse is a global randomized trial. The trial enrolled CRT-indicated patients with New York Heart Association classes II-IV HF, left bundle branch block (QRS ≥ 140 ms in men, ≥130 ms in women), and baseline PR interval ≤200 ms. In total, 3620 patients were randomized, including 1569 women (43.3%) approaching the actual proportion of women in the HF population. Women were older and more often New York Heart Association class III or IV than men (55.6% vs. 48.7%), had less frequent ischaemic cardiomyopathy (21.2% vs. 39.5%), and had a 5.1 ms shorter QRS duration than men. Women were more often depressed (18.5% vs. 9.7%), had a significantly lower Kansas City Cardiomyopathy Questionnaire score, and had differences in medication prescriptions. CONCLUSIONS: AdaptResponse is the largest randomized CRT trial and enrolled more women than any other landmark CRT trial. Women differed from men with regard to baseline characteristics and quality of life. Whether these differences translate into clinical outcome differences will be examined further in the AdaptResponse trial.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome in young women, with a wide clinical spectrum of severity. Ventricular arrhythmia (VA) can occur and worsen prognosis. The current study compared in-hospital and follow-up adverse cardiovascular events in patients with and without VA at presentation. METHODS: Eighty-three cases of SCAD were collected retrospectively from 4 Gulf countries (KSA, UAE, Kuwait, and Bahrain) during the period from January 2011 to December 2017. We divided the patients into 2 groups: those with and without VA at presentation. VA was defined as ventricular tachycardia and/or ventricular fibrillation. In-hospital (recurrent VA, cardiogenic shock, death, implantable cardioverter-defibrillator placement, dissection extension) and follow-up (MI, de novo SCAD, death, spontaneous superior mesenteric artery dissection) events were compared among the 2 groups. RESULTS: The median age of patients in the study was 44 (37-55) years. Forty-two (51%) were women. VA occurred in 10 (12%) patients in the first 24-hour of hospitalization, and 5 (50%) of those patients had recurrent in-hospital VA. Among those with recurrent VA, 1 died during hospitalization and 1 died within the first year following hospital discharge. CONCLUSIONS: In-hospital adverse cardiovascular events were significantly more frequent for patients with SCAD who presented with VA. However, follow-up events were not statistically significant between those with and without VA at presentation.
