RESUMEN
Background: Neurolotic sequelae after transcatheter aortic valve replacement (TAVR) can cause significant morbidity and mortality. Transcranial Doppler (TCD) imaging can show real-time high intensity transient signals (HITS), which reflect active microembolization. Although it is well known that intraprocedural microembolism occurs, it is not known if this embolic phenomenon continues in the postprocedural period. We investigated whether microemboli occur post-TAVR and whether we could determine any clinical, procedural, or echocardiographic predictors. Methods: We evaluated HITS in 51 consecutive patients undergoing unprotected TAVR with low-, intermediate-, or high-risk Society of Thoracic Surgeons score. Patients were excluded if they did not have temporal windows for insonation of the middle cerebral artery or if they were not willing to participate. Primary outcomes of HITS 24 hours post-TAVR were observed using a Philips iU22 TCD. TCD was performed at 3 time points (pre-, peri-, and post-TAVR) for each patient, before, during, and 24 hours postprocedure. Results: While no HITS were detected in any of the patients preoperatively, all patients had HITS during the procedure. Interestingly, 56.8% had HITS 24 hours post-TAVR. One patient with HITS post-TAVR had a stroke 48 hours after TAVR. Conclusion: We observed a high prevalence of microemboli 24 hours post-TAVR. None of the predictors for intraprocedural microembolism seemed to play an important role for post-TAVR microemboli.
RESUMEN
BACKGROUND: Empagliflozin improves cardiovascular outcomes in patients with heart failure, patients with type 2 diabetes who are at high cardiovascular risk, and patients with chronic kidney disease. The safety and efficacy of empagliflozin in patients who have had acute myocardial infarction are unknown. METHODS: In this event-driven, double-blind, randomized, placebo-controlled trial, we assigned, in a 1:1 ratio, patients who had been hospitalized for acute myocardial infarction and were at risk for heart failure to receive empagliflozin at a dose of 10 mg daily or placebo in addition to standard care within 14 days after admission. The primary end point was a composite of hospitalization for heart failure or death from any cause as assessed in a time-to-first-event analysis. RESULTS: A total of 3260 patients were assigned to receive empagliflozin and 3262 to receive placebo. During a median follow-up of 17.9 months, a first hospitalization for heart failure or death from any cause occurred in 267 patients (8.2%) in the empagliflozin group and in 298 patients (9.1%) in the placebo group, with incidence rates of 5.9 and 6.6 events, respectively, per 100 patient-years (hazard ratio, 0.90; 95% confidence interval [CI], 0.76 to 1.06; P = 0.21). With respect to the individual components of the primary end point, a first hospitalization for heart failure occurred in 118 patients (3.6%) in the empagliflozin group and in 153 patients (4.7%) in the placebo group (hazard ratio, 0.77; 95% CI, 0.60 to 0.98), and death from any cause occurred in 169 (5.2%) and 178 (5.5%), respectively (hazard ratio, 0.96; 95% CI, 0.78 to 1.19). Adverse events were consistent with the known safety profile of empagliflozin and were similar in the two trial groups. CONCLUSIONS: Among patients at increased risk for heart failure after acute myocardial infarction, treatment with empagliflozin did not lead to a significantly lower risk of a first hospitalization for heart failure or death from any cause than placebo.

BACKGROUND: Empagliflozin reduces the risk of heart failure (HF) events in patients with type 2 diabetes at high cardiovascular risk, chronic kidney disease, or prevalent HF irrespective of ejection fraction. Whereas the EMPACT-MI trial (Effect of Empagliflozin on Hospitalization for Heart Failure and Mortality in Patients With Acute Myocardial Infarction) showed that empagliflozin does not reduce the risk of the composite of hospitalization for HF and all-cause death, the effect of empagliflozin on first and recurrent HF events after myocardial infarction is unknown. METHODS: EMPACT-MI was a double-blind, randomized, placebo-controlled, event-driven trial that randomized 6522 patients hospitalized for acute myocardial infarction at risk for HF on the basis of newly developed left ventricular ejection fraction of <45% or signs or symptoms of congestion to receive empagliflozin 10 mg daily or placebo within 14 days of admission. In prespecified secondary analyses, treatment groups were analyzed for HF outcomes. RESULTS: Over a median follow-up of 17.9 months, the risk for first HF hospitalization and total HF hospitalizations was significantly lower in the empagliflozin compared with the placebo group (118 [3.6%] versus 153 [4.7%] patients with events; hazard ratio, 0.77 [95% CI, 0.60, 0.98]; P=0.031, for first HF hospitalization; 148 versus 207 events; rate ratio, 0.67 [95% CI, 0.51, 0.89]; P=0.006, for total HF hospitalizations). Subgroup analysis showed consistency of empagliflozin benefit across clinically relevant patient subgroups for first and total HF hospitalizations. The need for new use of diuretics, renin-angiotensin modulators, or mineralocorticoid receptor antagonists after discharge was less in patients randomized to empagliflozin versus placebo (all P<0.05). CONCLUSIONS: Empagliflozin reduced the risk of HF in patients with left ventricular dysfunction or congestion after acute myocardial infarction.

BACKGROUND: Empagliflozin reduces the risk of heart failure (HF) hospitalizations but not all-cause mortality when started within 14 days of acute myocardial infarction (AMI). OBJECTIVES: This study sought to evaluate the association of left ventricular ejection fraction (LVEF), congestion, or both, with outcomes and the impact of empagliflozin in reducing HF risk post-AMI. METHODS: In the EMPACT-MI (Trial to Evaluate the Effect of Empagliflozin on Hospitalization for Heart Failure and Mortality in Patients with Acute Myocardial Infarction) trial, patients were randomized within 14 days of an AMI complicated by either newly reduced LVEF<45%, congestion, or both, to empagliflozin (10 mg daily) or placebo and were followed up for a median of 17.9 months. RESULTS: Among 6,522 patients, the mean baseline LVEF was 41 ± 9%; 2,648 patients (40.6%) presented with LVEF <45% alone, 1,483 (22.7%) presented with congestion alone, and 2,181 (33.4%) presented with both. Among patients in the placebo arm of the trial, multivariable adjusted risk for each 10-point reduction in LVEF included all-cause death or HF hospitalization (HR: 1.49; 95% CI: 1.31-1.69; P < 0.0001), first HF hospitalization (HR: 1.64; 95% CI: 1.37-1.96; P < 0.0001), and total HF hospitalizations (rate ratio [RR]: 1.89; 95% CI: 1.51-2.36; P < 0.0001). The presence of congestion was also associated with a significantly higher risk for each of these outcomes (HR: 1.52, 1.94, and RR: 2.03, respectively). Empagliflozin reduced the risk for first (HR: 0.77; 95% CI: 0.60-0.98) and total (RR: 0.67; 95% CI: 0.50-0.89) HF hospitalizations, irrespective of LVEF or congestion, or both. The safety profile of empagliflozin was consistent across baseline LVEF and irrespective of congestion status. CONCLUSIONS: In patients with AMI, the severity of left ventricular dysfunction and the presence of congestion was associated with worse outcomes. Empagliflozin reduced first and total HF hospitalizations across the range of LVEF with and without congestion.

BACKGROUND: Data regarding the impact of reduced left ventricular ejection fraction (LVEF) and/or reduced mean aortic valve gradient (AVG) on outcomes following transcatheter aortic valve intervention (TAVI) have been conflicting. We sought to assess the relationship between LVEF, AVG, and 1-year mortality in patients undergoing TAVI. METHODS: We prospectively evaluated 298 consecutive adults undergoing TAVI from 2015 to 2018 at an academic tertiary medical center. Patients were categorized according to LVEF and mean AVG. The primary outcome of interest was all-cause mortality at 1 year. RESULTS: Of 298 adults undergoing TAVI, 66 (22.1%) had baseline LVEF ≤45% while 232 (77.9%) had baseline LVEF >45%; 173 (58.1%) had baseline AVG < 40mmHg while 125 (41.9%) had baseline AVG ≥ 40mmHg. Rates of 1-year all-cause mortality were significantly higher in patients with LVEF ≤45% (28.8% vs 12.1%, p = 0.001) and those with AVG < 40mmHg (19.7% vs 10.4%, p = 0.031) compared to those with LVEF >45% and AVG ≥ 40mmHg respectively. In multivariable analysis, higher AVG (per mmHg) (OR 0.97, 95% CI 0.94-0.99, p = 0.026) was noted to be independently associated with lower rates of 1-year mortality, while LVEF was not (OR 0.98, 95% CI 0.96-1.01). CONCLUSIONS: In this prospective, contemporary registry of adults undergoing TAVI, while 1-year unadjusted mortality rates are significantly higher in patients with reduced LVEF and reduced AVG, risk-adjusted mortality at 1 year is only higher in those with reduced AVG - not in those with reduced LVEF.

BACKGROUND: In-hospital cardiac arrest (IHCA) continues to be associated with high morbidity and mortality. The objective of this study was to study the association of arterial carbon dioxide tension (PaCO2) on survival to discharge and favorable neurologic outcomes in adults with IHCA. METHODS: The study population included 353 adults who underwent resuscitation from 2011 to 2019 for IHCA at an academic tertiary care medical center with arterial blood gas testing done within 24 hours of arrest. Outcomes of interest included survival to discharge and favorable neurologic outcome, defined as Glasgow outcome score of 4-5. RESULTS: Of the 353 patients studied, PaCO2 classification included: hypocapnia (PaCO2 <35 mm Hg, n = 89), normocapnia (PaCO2 35-45 mm Hg, n = 151), and hypercapnia (PaCO2 >45 mm Hg, n = 113). Hypercapnic patients were further divided into mild (45 mm Hg < PaCO2 ≤55 mm Hg, n = 62) and moderate/severe hypercapnia (PaCO2 > 55 mm Hg, n = 51). Patients with normocapnia had the highest rates of survival to hospital discharge (52.3% vs. 32.6% vs. 30.1%, P < 0.001) and favorable neurologic outcome (35.8% vs. 25.8% vs. 17.9%, P = 0.005) compared those with hypocapnia and hypercapnia respectively. In multivariable analysis, compared to normocapnia, hypocapnia [odds ratio (OR), 2.06; 95% confidence interval (CI), 1.15-3.70] and hypercapnia (OR, 2.67; 95% CI, 1.53-4.66) were both found to be independently associated with higher rates of in-hospital mortality. Compared to normocapnia, while mild hypercapnia (OR, 2.53; 95% CI, 1.29-4.97) and moderate/severe hypercapnia (OR, 2.86; 95% CI, 1.35-6.06) were both independently associated with higher in-hospital mortality compared to normocapnia, moderate/severe hypercapnia was also independently associated with lower rates of favorable neurologic outcome (OR, 0.28; 95% CI, 0.11-0.73), while mild hypercapnia was not. CONCLUSIONS: In this prospective registry of adults with IHCA, hypercapnia noted within 24 hours after arrest was independently associated with lower rates of survival to discharge and favorable neurologic outcome.

Patients with severe aortic stenosis (AS) may develop heart failure (HF), the presence of which has traditionally been deemed as a final stage in AS progression with poor outcomes. The use of transcatheter aortic valve replacement (TAVR) has become the preferred therapy for most patients with AS and concomitant HF. With its instant afterload reduction, TAVR offers patients with HF significant haemodynamic benefits, with corresponding changes in left ventricular structure and improved mortality and quality of life. The prognostic covariates and optimal timing of TAVR in patients with less than severe AS remain unclear. The purpose of this review is to describe the association between TAVR and outcomes in patients with HF, particularly in the setting of left ventricular systolic dysfunction, acute HF, and right ventricular systolic dysfunction, and to highlight areas for future research.

BACKGROUND: The beneficial role of dual anti-platelet therapy (DAPT) in coronary artery disease is well established. However, there is limited data describing the effects of DAPT in patients with atherosclerotic peripheral artery disease (PAD). The aim of this meta-analysis is to compare clinical outcomes associated with DAPT versus single anti-platelet therapy (SAPT) in patients with symptomatic PAD. METHODS: We performed a literature search for studies assessing the risk of adverse cardiovascular and limb events in cohorts receiving either DAPT or SAPT. The primary endpoint was all cause mortality. The secondary endpoints included graft failure, amputation, total bleeding, severe bleeding and fatal bleeding. The search included the following databases: Ovid MEDLINE, EMBASE, Web of Science, and Google Scholar. The search was not restricted to time or publication status. RESULTS: A total of 11 studies with 54,331 participants (24,449 on SAPT and 29,882 on DAPT) were included. Patients with PAD treated with SAPT had higher all-cause mortality compared to patients treated with DAPT (OR 1.37, 95 % CI 1.09-1.74; p < 0.01). There was no difference in risk of graft failure or amputation between patients treated with SAPT or DAPT (OR 0.9, 95 % CI 0.77-1.06; p = 0.19; OR 1.11, 95 % CI 0.88-1.41; p = 0.37). Patients treated with SAPT had lower total bleeds compared to patients treated with DAPT (OR 0.53, 95 % CI 0.36-0.77; p < 0.01). However, For SAPT plus AC vs SAPT, a total of 8 studies with 17,100 participants (3447 with SAPT plus AC and 8619 with only SAPT) were included. Patients on SAPT plus AC did not have a statistically significant difference in risk for all-cause mortality, (OR 0.91, 95 % CI 0.67-1.24; p = 0.56). SAPT plus AC had significantly lower risk of MI (OR 0.82, 95 % CI 0.69-0.97; p = 0.02), amputation (OR 0.72, 95 % CI 0.53-0.97; p = 0.03), and graft failure (OR 0.66, 95 % CI 0.48-0.93; p = 0.02). There was no significant different in risk of fatal bleeding be-tween the two groups (OR 1.60, 95 % CI 0.76-3.35; p = 0.22). CONCLUSIONS: In patients with symptomatic PAD, a strategy of DAPT may confer a mortality benefit when compared to SAPT without significantly increasing the risk of serious bleeding events.

AIMS: The therapeutic mechanism of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on left cardiac remodelling in patients with heart failure with reduced ejection fraction (HFrEF) is not well-established. This study meta-analysed the impact of SGLT2i on left cardiac structure and function in patients with HFrEF. METHODS AND RESULTS: Online databases were queried up to April 2023 for trials reporting indicators of left cardiac structure and function in patients with HFrEF treated with SGLT2i. Data from studies were pooled using a random-effects model to derive weighted mean differences (WMDs) and 95% confidence intervals (CIs). Six trials were included (n = 555). Compared with control, SGLT2i significantly improved left ventricular end-diastolic volume (LVEDV; WMD: -17.07 ml [-23.84, -10.31]; p < 0.001), LVEDV index (WMD: -5.62 ml/m2 [-10.28, -0.97]; p = 0.02), left ventricular end-systolic volume (LVESV; WMD: -15.63 ml [-26.15, -5.12]; p = 0.004), LVESV index (WMD: -6.90 ml/m2 [-10.68, -3.11]; p = 0.001), left ventricular ejection fraction (WMD: 2.71% [0.70, 4.72]; p = 0.008), and left atrial volume index (WMD: -2.19 ml/m2 [-4.26, -0.11]; p = 0.04) in patients with HFrEF. SGLT2i use was associated with a non-significant trend towards a reduction in left ventricular mass index (WMD: -6.25 g/m2 [-12.79, 0.28]; p = 0.06). No significant impact on left ventricular global longitudinal strain was noted (WMD: 0.21% [-0.25, 0.67]; p = 0.38). CONCLUSIONS: Sodium-glucose cotransporter 2 inhibitors improve cardiac structure and function in patients with HFrEF.

BACKGROUND: The association between Medicare Severity-Diagnosis Related Group (DRG) and early and intermediate-term outcomes in patients undergoing transcatheter aortic valve implantation (TAVI) has not been well studied. We aimed to assess the relationship between DRG and 30-day and 1-year mortality in patients undergoing TAVI. METHODS: The study population included 289 patients with severe symptomatic AS who underwent TAVI from December 2015 to June 2018 at an academic tertiary care medical center. Patients were categorized as DRG 266 or DRG 267, specifying TAVI with or without major complication or comorbidities respectively. RESULTS: Of the 289 patients, 182 patients (63.0%) were classified under DRG 267 and 107 patients (37.0%) under DRG 266. The DRG 266 group had longer hospital lengths of stay and higher rates of discharge to a skilled nursing facility. While rates of in-hospital and 30-day mortality were similar in both DRG groups, the DRG 266 group had higher 1-year all-cause mortality (26.2% vs 8.8%, P less than .001). In multivariable analysis, serum creatinine (OR 1.42, 95%CI 1.05-1.93) was the only independent predictor of 1-year mortality in the DRG 266 group while atrial fibrillation (OR 3.04, 95%CI 1.03-8.92) was the only independent predictor of mortality in the DRG 267 group. CONCLUSIONS: In this prospective registry of patients undergoing TAVI, while rates of in-hospital and 30-day mortality were similar in both DRG 266 and 267 groups, the DRG 266 group had higher 1-year all-cause mortality. Distinct predictors of mortality in each DRG group exist.

BACKGROUND: Pre-procedural fasting to reduce aspiration risk is usual care prior to surgery requiring anesthesia. Prolonged fasting, however, can result in dehydration and may adversely affect patient experience and outcomes. Previous studies suggest that providing a supplemental beverage to patients undergoing cardiac and a variety of other surgical procedures improves patients' subjective assessment of thirst and hunger and potentially decreases the need for inotrope and vasopressor therapy. Less is known, however, about the effects of ad libitum clear liquids up to 2 h prior to surgery. METHODS: Adult patients undergoing transcatheter aortic valve replacement (TAVR) or arrhythmia ablation were randomized (1:1) to ad libitum clear liquids up to 2 h prior to their procedure vs. nil per os (NPO) after midnight (control group, usual care). The primary endpoint was a composite satisfaction score that included patient-reported thirst, hunger, headache, nausea, lightheadedness, and anxiousness prior to surgery. The incidence of case-delay was recorded. Intraoperative vasopressor administration, changes in creatinine, anti-emetic use, and hospital length of stay (LOS) were recorded. Safety endpoints including aspiration were assessed. RESULTS: A total of 200 patients were randomized and 181 patients were included in the final analysis. Overall, 92% of patients were ASA class III or IV and 23% of patients had NYHA class III or IV symptoms. Groups were well balanced with no significant differences in age, sex or baseline cardiac or renal disease. The composite satisfaction score (primary endpoint) was not significantly different between groups (Ad libitum median = 12, IQR = [6, 17], vs Standard NPO median = 10, IQR = [5, 15], [95% CI = [-1, 4]). No significant differences between the two groups were observed in any of the individual survey questions (thirst, hunger, headache, nausea, lightheadedness, anxiousness). No significant differences between groups were observed for intra-operative vasopressor use, changes in creatinine, rescue anti-emetic use or hospital LOS. There were no case delays attributed to the intervention. There were no cases of suspected aspiration. CONCLUSION: No adverse events or case delays were observed in the ad libitum clears group. No significant benefit, however, was observed in patient satisfaction or any of the pre-specified secondary endpoints in patients randomized to ad libitum clear liquids up to 2 h prior to their procedure.

RESUMEN
BACKGROUND: Heart failure (HF) may complicate acute coronary syndrome (ACS) and is associated with a high burden of short- and long-term morbidity and mortality. Only limited data regarding future ischemic events and rehospitalization are available for patients who suffer HF before or during ACS. METHODS: A secondary analysis of 4 large ACS trials (PLATO, APPRAISE-2, TRACER, and TRILOGY ACS) using Cox proportional hazards models was performed to investigate the association of HF status (no HF, chronic HF, de novo HF) at presentation for ACS with all-cause and cardiovascular death, major adverse cardiovascular event (MACE ), myocardial infarction, stroke, and hospitalization for heart failure (HHF) by 1 year. Cumulative incidence plots are presented at 30 days and 1 year. RESULTS: A total of 11.1% of the 47,474 patients presenting with ACS presented with evidence of acute HF, 55.0% of whom presented with de novo HF. Patients with chronic HF presented with evidence of acute HF at a higher rate than those with no previous HF (40.3% vs 6.9%). Compared to those without HF, those with chronic and de novo HF had higher rates of all-cause mortality (adjusted hazard ratio [aHR] 2.01, 95% confidence interval [CI] 1.72-2.34 and aHR 1.47, 95% CI1.15-1.88, respectively), MACE (aHR 1.47, 95% CI1.31-1-.66 and aHR 1.38, 95% CI1.12-1.69), and HHF (aHR 2.29, 95% CI2.02-2.61 and aHR 1.48, 95% CI 1.20-1.82) at 1 year. CONCLUSION: In this large cohort of patients with ACS, both prior and de novo HF complicating ACS were associated with significantly higher risk-adjusted rates of death, ischemic events and HHF at 30 days and 1 year. Further studies examining the association between HF and outcomes in this high-risk population are warranted, especially given the advent of more contemporary HF therapies.

In recent years, the treatment of aortic stenosis with TAVR has rapidly expanded to younger and lower-risk patients. However, persistent thrombotic events such as stroke and valve thrombosis expose recipients to severe clinical complications that hamper TAVR's rapid advance. We presented a novel methodology for establishing a link between commonly acceptable mild paravalvular leak (PVL) levels through the device and increased thrombogenic risk. It utilizes in vitro patient-specific TAVR 3D-printed replicas evaluated for hydrodynamic performance. High-resolution µCT scans are used to reconstruct in silico FSI models of these replicas, in which multiple platelet trajectories are studied through the PVL channels to quantify thrombogenicity, showing that those are highly dependent on patient-specific flow conditions within the PVL channels. It demonstrates that platelets have the potential to enter the PVL channels multiple times over successive cardiac cycles, increasing the thrombogenic risk. This cannot be reliably approximated by standard hemodynamic parameters. It highlights the shortcomings of subjectively ranked PVL commonly used in clinical practice by indicating an increased thrombogenic risk in patient cases otherwise classified as mild PVL. It reiterates the need for more rigorous clinical evaluation for properly diagnosing thrombogenic risk in TAVR patients.

Although gender-related disparities in intermediate-term outcomes have been reported after transcatheter aortic valve implantation (TAVI), disparate predictors of mortality in men and women who underwent TAVI have not been well studied. This prospective institutional registry study included 297 consecutive patients (153 men, 144 women) who underwent transfemoral TAVI from December 2015 to June 2018 at an academic tertiary medical center. Baseline and clinical characteristics, procedural data, and clinical outcomes at 1 year were recorded. Mortality rates at 1 year were 11.1% and 20.3% in women and men, respectively (p = 0.033). Risk-adjusted mortality was significantly higher in men who underwent TAVI than in women (odds ratio [OR] 2.45, 95% confidence interval [CI] 1.24 to 4.87, p = 0.010). Gender-specific risk-adjusted predictors of 1-year mortality post-TAVI included the presence of atrial fibrillation (OR 4.20, 95% CI 1.31 to 13.46, p = 0.016) and peripheral artery disease (OR 4.64, 95% CI 1.04 to 20.71, p = 0.044) in women and presence of chronic obstructive pulmonary disease (OR 3.14, 95% CI 1.13 to 8.72, p = 0.029), higher serum creatinine (OR 1.57, 95% CI 1.15 to 2.15, p = 0.004), and lower body mass index (OR 0.88, 95% CI 0.80 to 0.97, p = 0.008) in men. In this prospective institutional registry of adults who underwent TAVI, risk-adjusted 1-year mortality is significantly lower in women, and disparate predictors of risk-adjusted 1-year mortality exist in men and women.

BACKGROUND: Pulmonary hypertension (PH) has been associated with poor survival in multiple cardiopulmonary conditions, however its association with outcomes in cardiac arrest remains unknown. We aimed to evaluate the association of PH with survival and neurologic outcomes in adults with in-hospital cardiac arrest (IHCA). METHODS: The study population included adults with IHCA undergoing resuscitation at an academic tertiary-care medical center from 2011 to 2019. Patients were classified based upon the presence versus absence of PH, defined as a pulmonary artery systolic pressure >35 mmHg on pre-arrest echocardiogram. Survival to discharge and favorable neurological outcome (defined as a Glasgow Outcome Score of 4-5) served as the primary and secondary outcomes of interest respectively. RESULTS: Of the 371 patients studied, 203 (54.7%) had PH while 168 (45.3%) did not. Patients with PH had higher Charlson Comorbidity Score with higher rates of multiple baseline comorbidities. They also had worse multi-chamber enlargement, left ventricular diastolic dysfunction, right ventricular systolic dysfunction, and valvular heart disease compared to non-PH patients. Rates of survival to discharge (11.5% vs 10.9%, p = 0.881) and favorable neurologic outcome (8.0% vs 6.2%, p = 0.550) were similar in PH and non-PH patients respectively. In multivariable analysis, PH was not associated with survival to discharge (OR 1.23, 95%CI 0.57-2.65) or favorable neurologic outcome (OR 1.69, 95%CI 0.64-4.45). CONCLUSIONS: In this contemporary registry of adults with IHCA, while PH was associated with a higher risk patient profile, it was not associated with survival or neurologic outcomes in this population.
