The optimal methods for measuring and analyzing anal resting and squeeze pressure with high-resolution manometry (HRM) are unclear.Anal resting and squeeze pressures were measured with HRM in 90 healthy women, 35 women with defecatory disorders (DD), and 85 with fecal incontinence (FI). Pressures were analyzed with Manoview™ software and a customized approach. Resting pressures measured for 20, 60, and 300 s were compared. During the squeeze period, (3 maneuvers, 20 s each), the squeeze increment, which was averaged over 5, 10, 15, and 20 s, and squeeze duration were evaluated.Compared to healthy women, the anal resting pressure, squeeze pressure increment, and squeeze duration were lower in FI (p ≤ 0.04) but not in DD. The 20, 60, and 300 s resting pressures were strongly correlated (concordance correlation coefficients = 0.96-0.99) in healthy and DD women. The 5 s squeeze increment was the greatest; 10, 15, and 20 s values were progressively lower (p 0.001). The squeeze pressure increment and duration differed (p 0.01) among the three maneuvers in healthy and DD women but not in FI women. The upper 95th percentile limit for squeeze duration was 19.5 s in controls, 19.9 s in DD, and 19.3 s in FI. Adjusted for age, resting pressure, and squeeze duration, a greater squeeze increment was associated with a lower risk of FI versus health (OR, 0.96; 95% CI, 0.94-0.97).These findings suggest that anal resting and squeeze pressures can be accurately measured over 20 s. In most patients, one squeeze maneuver is probably sufficient.

Background: Coronary artery disease (CAD) is a common cause of heart failure (HF). Whether the extent of coronary artery stenosis differs by HF type or prognosis for patients admitted with acute decompensated heart failure (ADHF) is uncertain. Methods: The Atherosclerosis Risk in Communities (ARIC) study conducted hospital surveillance of adjudicated HF in 4 US areas from 2005-2014. Medical histories were abstracted from the hospital record. Obstructive CAD was defined as > 49% stenosis in the left main coronary artery or >74% stenosis in the other major coronary arteries. Associations between obstructive CAD and 28-day mortality were analyzed separately for heart failure with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF), adjusting for age, race, sex, year of admission, and coronary revascularization procedures. All analyses were weighted by the inverse of the sampling probability. Results: A total of 5115 patients admitted with ADHF underwent coronary angiography during the hospital visit (mean age = 72, 45% women, 28% Black, 30% HFpEF). Obstructive CAD was more prevalent with HFrEF ( Figure 1 ), whether at the left main coronary artery (16% vs 12%), left anterior descending artery (50% vs 35%), left circumflex artery (42% vs 34%), right coronary artery (45% vs 34%), or multiple coronary vessels (47% vs 34%). A similar proportion of patients with obstructive CAD underwent revascularization, irrespective of HF type (HFrEF: 55%, HFpEF: 61%). After adjustments, obstructive CAD (in any vessel) was associated with higher 28-day mortality, both for HFrEF (OR: 3.21; CI: 1.91 - 5.97) and HFpEF (OR: 3.62; 95% CI: 1.43 - 9.18) with no significant interaction by HF type ( P -interaction = 0.9). Conclusion: Patients hospitalized with ADHF and coexisting obstructive CAD are at greater risk of short-term mortality, irrespective of the HF type, warranting the need for effective interventions as well as secondary preventive measures in this population.

Introduction The prevalence and outcomes of polyvascular disease (PVD) in patients admitted with acute decompensated heart failure (ADHF) have not been previously reported, nor is it known whether associations differ for heart failure (HF) with reduced vs. preserved ejection fraction (HFrEF vs HFpEF, respectively). Purpose To investigate the relationship between atherosclerotic involvement of multiple arterial territories and mortality in patients hospitalized with ADHF. Methods The Atherosclerosis Risk in Communities (ARIC) study conducted hospital surveillance of adjudicated heart failure in 4 US areas from 2005–2014, with events verified by physician review. Medical histories were abstracted from the hospital record. PVD was defined by coexisting disease in ≥2 arterial beds, identified by prevalent coronary artery disease, peripheral arterial disease, and cerebrovascular disease. Mortality hazards of PVD vs. no PVD were analyzed separately for HFpEF and HFrEF, with adjustment for age, race, sex, year of admission and geographic region. All analyses were weighted by the inverse of the sampling probability. Results Of 24,936 ADHF hospitalizations (52% female, 32% Black, mean age 75 years), 19% had PVD (22% among HFrEF hospitalizations, 17% among HFpEF hospitalizations), Figure 1. There was an increasing trend in 1-year mortality with 0, 1 and ≥2 arterial bed involvement, both for patients with HFrEF (29% to 32% to 38%; P-trend=0.0006) and HFpEF (26% to 32% to 37%; P-trend Conclusion Patients hospitalized with ADHF and coexisting PVD have an increased risk of death, irrespective of HF type. Clinical attention should be directed toward PVD, with secondary prevention strategies enacted to improve the prognosis of this vulnerable population.

An expanding number of therapies are now indicated for comorbidity management in heart failure with preserved ejection fraction (HFpEF). Whether comorbidity burdens differ for patients with HFpEF who are hospitalized for acute decompensated heart failure (ADHF) versus those with chronic stable heart failure (CSHF) who are hospitalized for other causes is uncertain. Since 2005, the Atherosclerosis Risk in Communities (ARIC) study has conducted adjudicated community surveillance of hospitalized heart failure. Hospitalized ADHF and CSHF were sampled identically, using prespecified discharge codes and demographic strata, but were differentiated by signs or symptoms of acute or worsening heart failure upon physician review of the medical record. HFpEF was defined by an ejection fraction ≥50%. All events were weighted by the inverse of the sampling probability for statistical analyses. From 2005 to 2014, 13,706 weighted (2,936 unweighted) hospitalizations (mean age 77 years, 64% women, 29% Black) were sampled among patients with HFpEF and adjudicated ADHF (86%) or CSHF (14%). Comorbidity prevalence was high both for ADHF and CSHF hospitalizations, irrespective of gender. Women hospitalized with ADHF versus CSHF had greater prevalence of hypertension (89% vs 84%) diabetes mellitus (48% vs 39%) and renal disease (85% vs 74%). Echocardiographic features such as left ventricular hypertrophy and valvular abnormalities were more common with ADHF than CSHF, for both genders. However, the 28-day and 1-year mortality risk were comparable for ADHF and CSHF. In conclusion, hospitalized patients with HFpEF have a high comorbidity burden and risk of death, irrespective of the cause of hospitalization.

Aims Shock index (SI), defined as the ratio of heart rate (HR) to systolic blood pressure (SBP), is easily obtained and predictive of mortality in patients with ST-segment elevation myocardial infarction. However, large-scale evaluations of SI in patients with non-ST-segment elevation myocardial infarction (NSTEMI) are lacking. Methods and results Hospitalizations for acute myocardial infarction were sampled from four US areas by the Atherosclerosis Risk in Communities (ARIC) study and classified by physician review. Shock index was derived from the HR and SBP at first presentation and considered high when ≥0.7. From 2000 to 2014, 18 301 weighted hospitalizations for NSTEMI were sampled and had vitals successfully obtained. Of these, 5753 (31%) had high SI (≥0.7). Patients with high SI were more often female (46% vs. 39%) and had more prevalent chronic kidney disease (40% vs. 32%). TIMI (Thrombolysis in Myocardial Infarction) risk scores were similar between the groups (4.3 vs. 4.2), but GRACE (Global Registry of Acute Coronary Syndrome) score was higher with high SI (140 vs. 118). Angiography, revascularization, and guideline-directed medications were less often administered to patients with high SI, and the 28-day mortality was higher (13% vs. 5%). Prediction of 28-day mortality by SI as a continuous measurement [area under the curve (AUC): 0.68] was intermediate to that of the GRACE score (AUC: 0.87) and the TIMI score (AUC: 0.54). After adjustments, patients with high SI had twice the odds of 28-day mortality (odds ratio = 2.02; 95% confidence interval: 1.46–2.80). Conclusion The SI is easily obtainable, performs moderately well as a predictor of short-term mortality in patients hospitalized with NSTEMI, and may be useful for risk stratification in emergency settings.

Introduction: Shock index (SI), defined as the ratio of heart rate (HR) to systolic blood pressure (SBP), is easily obtained and has been reported to predict all-cause mortality in acute myocardial infarction (AMI) hospitalizations, primarily among patients with STEMI. Large-scale investigations examining the prognostic value of SI in patients with NSTEMI are lacking. Methods: Hospitalizations for acute myocardial infarction were sampled from 4 US areas by the ARIC Study and classified by physician review. HR and SBP at first presentation were abstracted from the medical record. Pulseless patients, those with unobtainable SBP, and transfer patients were excluded. An SI value ≥0.7 was considered high. The TIMI risk score for NSTE-ACS was calculated using the established algorithm. Predictions of all-cause 28-day mortality were analyzed using receiver operating characteristics (ROC). Results: From 2000-2014, 18,301 weighted hospitalizations for NSTEMI patients were sampled and had vitals successfully obtained. Of these, 5753 (31%) had high SI (≥0.7). Patients with high SI were more often female (46% vs 39%) and older (65 vs 63 years), with more prevalent chronic kidney disease (40% vs. 32%), pneumonia (16% vs 8%), and complication by acute heart failure (42% vs 30%). However, the TIMI risk score was comparable for the 2 groups (4.3 vs. 4.2). Angiography (36% vs 58%), revascularization (19% vs 41%), and guideline-directed medications were less often administered to patients with high SI, and the 28-day mortality was nearly 3 times higher (13% vs 5%). Continuous values of SI were more predictive of 28-day mortality than the TIMI risk score, both overall (ROC-AUC: 0.68 vs 0.54; P P Conclusion: The SI outperformed the TIMI risk score for prediction of short-term mortality in patients hospitalized with NSTEMI, and may be useful for risk stratification in emergency settings.

Background Peripheral artery disease (PAD) is both a common comorbidity and a contributing factor to heart failure. Whether PAD is associated with hospitalization for recurrent decompensation among patients with established heart failure is uncertain. Methods and Results Since 2005, the ARIC (Atherosclerosis Risk in Communities) study has conducted active surveillance of hospitalized acute decompensated heart failure (ADHF), with events verified by physician review. From 2005 to 2016, 1481 patients were hospitalized with ADHF and discharged alive (mean age, 78 years; 69% White). Of these, 207 (14%) had diagnosis of PAD. Those with PAD were more often men (55% versus 44%) and smokers (17% versus 8%), with a greater prevalence of coronary artery disease (72% versus 52%). Patients with PAD had an increased risk of at least 1 ADHF readmission, both within 30 days (11% versus 7%) and 1 year (39% versus 28%) of discharge from the index hospitalization. After adjustments, PAD was associated with twice the hazard of ADHF readmission within 30 days (HR, 2.02; 95% CI, 1.14–3.60) and a 60% higher hazard of ADHF readmission within 1 year (HR, 1.60; 95% CI, 1.25–2.05). The 1‐year hazard of ADHF readmission associated with PAD was stronger with heart failure with reduced ejection fraction (HR, 2.01; 95% CI, 1.29–3.13) than preserved ejection fraction (HR, 1.04; 95% CI, 0.69–1.56); P for interaction=0.05. Conclusions Patients with ADHF and concomitant PAD have a higher likelihood of ADHF readmission. Strategies to prevent ADHF readmissions in this high‐risk group are warranted.
