RESUMEN
BACKGROUND: Hyperpolypharmacy is associated with adverse outcomes in older adults, but because literature on its association with cardiovascular (CV) outcomes after acute decompensated heart failure (ADHF) is sparse, we investigated the relationships among hyperpolypharmacy, medication class, and death in patients with HF.MethodsâandâResults: We evaluated the total number of medications prescribed to 884 patients at discharge following ADHF. Patients were categorized into nonpolypharmacy (<5 medications), polypharmacy (5-9 medications), and hyperpolypharmacy (≥10 medications) groups. We examined the relationship of polypharmacy status with the 2-year mortality rate. The proportion of patients taking ≥5 medications was 91.3% (polypharmacy, 55.3%; hyperpolypharmacy, 36.0%). Patients in the hyperpolypharmacy group showed worse outcomes than patients in the other 2 groups (P=0.002). After multivariable adjustment, the total number of medications was significantly associated with an increased risk of death (hazard ratio [HR] per additional increase in the number of medications, 1.05; 95% confidence interval [CI], 1.01-1.10; P=0.027). Although the number of non-CV medications was significantly associated with death (HR, 1.07; 95% CI, 1.02-1.13; P=0.01), the number of CV medications was not (HR, 1.01; 95% CI, 0.92-1.10; P=0.95). CONCLUSIONS: Hyperpolypharmacy due to non-CV medications was associated with an elevated risk of death in patients after ADHF, suggesting the importance of a regular review of the prescribed drugs including non-CV medications.

BACKGROUND: Acute decompensated heart failure (ADHF) has a poor prognosis and common comorbidities may be contributory. However, evidence for the association between dementia and clinical outcomes in patients with is sparse and it requires further investigation into risk reduction.MethodsâandâResults: We assessed the clinical profiles and outcomes of 1,026 patients (mean age 77.8 years, 43.2% female) with ADHF enrolled in the CURE-HF registry to evaluate the relationship between investigator-reported dementia status and clinical outcomes (all-cause death, cardiovascular (CV) death, non-CV death, and HF hospitalization) over a median follow-up of 2.7 years. In total, dementia was present in 118 (11.5%) patients, who experienced more drug interruptions and HF admissions due to infection than those without dementia (23.8% vs. 13.1%, P<0.01; 11.0% vs. 6.0%, P<0.01, respectively). Kaplan-Meier analysis revealed that dementia patients had higher mortality rates than those without dementia (log-rank P<0.001). After multivariable adjustment for demographics and comorbidities, dementia was significantly associated with an increased risk of death (adjusted hazard ratio, 1.43; 95% confidence interval, 1.06-1.93, P=0.02) and non-CV death (adjusted hazard ratio, 1.65; 95% confidence interval, 1.04-2.62, P=0.03), but no significant associations between dementia and CV death or HF hospitalization were observed (both, P>0.1). CONCLUSIONS: In ADHF patients dementia was associated with aggravating factors for HF admission and elevated risk of death, primarily non-CV death.

Peripheral artery disease (PAD) is commonly caused by atherosclerosis and has an unfavorable prognosis. Complete revascularization (CR) of the coronary artery reduces the risk of major adverse cardiovascular event (MACE) in patients with coronary artery disease (CAD). However, the impact of CR in patients with PAD has not been established to date. Therefore, we evaluated the impact of CR of CAD on the five-year clinical outcomes in patients with PAD. This study was based on a prospective, multicenter, observational registry in Japan. We enrolled 366 patients with PAD undergoing endovascular treatment. The primary endpoint was MACE, defined as a composite of all-cause death, non-fatal myocardial infarction, and non-fatal stroke. After excluding ineligible patients, 96 and 68 patients received complete revascularization of the coronary artery (CR group) and incomplete revascularization of the coronary artery (ICR group), respectively. Freedom from MACE in the CR group was significantly higher than in the ICR group at 5 years (66.7% vs 46.0%, p < 0.01). Multivariate analysis revealed that CR emerged as an independent predictor of MACE (Hazard ratio: 0.56, 95% confidential interval: 0.34-0.94, p = 0.03). CR of CAD was significantly associated with improved clinical outcomes in patients with PAD undergoing endovascular treatment.

PURPOSE OF REVIEW: Various definitions of periprocedural myocardial infarction (MI) have been proposed by academic groups and professional societies differing in terms of biomarker thresholds and ancillary criteria for myocardial ischemia. The incidence and clinical significance of periprocedural MI substantially varies according to the definitions applied. In this review, we summarize available clinical data on the frequency and outcomes of periprocedural MI according to various MI definitions in patients undergoing percutaneous coronary intervention (PCI). RECENT FINDINGS: Numerous clinical studies and meta-analyses have investigated the incidence and prognostic relevance of periprocedural MI following PCI. The incidence of periprocedural MI was higher when defined by universal definition of myocardial infarction (UDMI), which applies a lower biomarker threshold with broader ancillary criteria compared with the Society for Cardiovascular Angiography and Intervention (SCAI) and academic research consortium (ARC)-2. The prognostic impact of periprocedural MI defined by SCAI and ARC-2 on mortality was consistently greater compared with the UDMI definition. SUMMARY: Among chronic coronary syndrome patients undergoing PCI, the frequency and prognostic value of periprocedural MI varies considerably based on definitions. Periprocedural MI defined by the ARC-2 and SCAI occurred 3-6 times less frequently and were prognostically more relevant as compared with the UDMI. Clinically relevant definitions should be used in daily practice and clinical trials.

BACKGROUND: Little evidence is available regarding the long-term outcome in elderly patients after deferral of revascularization based on fractional flow reserve (FFR).MethodsâandâResults: From the J-CONFIRM registry (long-term outcomes of Japanese patients with deferral of coronary intervention based on fractional flow reserve in multicenter registry), 1,262 patients were divided into 2 groups according to age: elderly and younger patients (aged ≥75 or <75 years, respectively). The primary endpoint was the cumulative 5-year incidence of target vessel failure (TVF), defined as a composite of cardiac death, target vessel-related myocardial infarction (TVMI), and clinically driven target vessel revascularization (CDTVR). Cumulative 5-year incidence of TVF was not significantly different between elderly and younger patients (14.3% vs. 10.8%, P=0.12). Cardiac death occurred more frequently in elderly patients than younger patients (4.4% vs. 0.8%, P<0.001), whereas TVMI and CDTVR did not differ between groups (1.3% vs. 0.9%, P=0.80; 10.7% vs. 10.1%, P=0.80, respectively). FFR values in lesions with diameter stenosis <50% were significantly higher in elderly patients than in younger patients (0.88±0.07 vs. 0.85±0.07, P=0.01), whereas this relationship was not observed in those with diameter stenosis ≥50%. CONCLUSIONS: Elderly patients had no excess risk of ischemic events related to the deferred coronary lesions by FFR, although FFR values in mild coronary artery stenosis were modestly different between elderly and younger patients.

Significant improvements in percutaneous coronary intervention (PCI) technology have enabled cardiovascular procedures to be performed without onsite cardiac surgery facilities. However, little is known about the association between onsite cardiac surgical support and long-term outcomes of PCI, particularly among emergent and complex cases. We investigated whether the presence or absence of cardiovascular surgery affects the long-term prognosis after PCI, emergent and complex elective cases. The SHINANO 5-year registry, a prospective, observational, and multicenter cohort study registry in Nagano, Japan, consecutively included 1665 patients who underwent PCI between August 2012 and July 2013. The procedures were performed at 11 hospitals with onsite cardiac surgery facilities [onsite surgery (+) group; n = 1257] and 8 hospitals without onsite cardiac surgery facilities [onsite surgery (-) group; n = 408]. The primary endpoint was all-cause mortality and the secondary endpoint was major adverse cardiac and cerebrovascular events [MACCE: all-cause death, Q-wave myocardial infarction, non-fatal stroke, and target lesion revascularization]. The onsite surgery group (+) had a lower rate of emergent PCI and ST-segment elevation myocardial infarction (40.8% vs. 51.7%, p < 0.01 and 24.9% vs. 39.2%, p < 0.01, respectively), and a higher prevalence of hemodialysis and history of peripheral artery disease (7.6% vs. 2.45%, p < 0.01 and 12.1% vs. 6.9%, p < 0.01, respectively). However, the Kaplan-Meier analysis showed no difference in the 5-year mortality rate (16.4% vs. 15.2%, p = 0.421) and MACCE incidence (31.6% vs. 28.9%, p = 0.354) between the groups. Also, there were no differences in the mortality rate and incidence of MACCE among emergent cases of ST-segment elevation myocardial infarction and complex elective cases who underwent PCI. Long-term outcomes of PCI appear to be comparable between institutions with and without onsite cardiac surgical facilities.

Importance: Coronary plaques that are prone to rupture and cause adverse cardiac events are characterized by large plaque burden, large lipid content, and thin fibrous caps. Statins can halt the progression of coronary atherosclerosis; however, the effect of the proprotein convertase subtilisin kexin type 9 inhibitor alirocumab added to statin therapy on plaque burden and composition remains largely unknown. Objective: To determine the effects of alirocumab on coronary atherosclerosis using serial multimodality intracoronary imaging in patients with acute myocardial infarction. Design, Setting, and Participants: The PACMAN-AMI double-blind, placebo-controlled, randomized clinical trial (enrollment: May 9, 2017, through October 7, 2020; final follow-up: October 13, 2021) enrolled 300 patients undergoing percutaneous coronary intervention for acute myocardial infarction at 9 academic European hospitals. Interventions: Patients were randomized to receive biweekly subcutaneous alirocumab (150 mg; n = 148) or placebo (n = 152), initiated less than 24 hours after urgent percutaneous coronary intervention of the culprit lesion, for 52 weeks in addition to high-intensity statin therapy (rosuvastatin, 20 mg). Main Outcomes and Measures: Intravascular ultrasonography (IVUS), near-infrared spectroscopy, and optical coherence tomography were serially performed in the 2 non-infarct-related coronary arteries at baseline and after 52 weeks. The primary efficacy end point was the change in IVUS-derived percent atheroma volume from baseline to week 52. Two powered secondary end points were changes in near-infrared spectroscopy-derived maximum lipid core burden index within 4 mm (higher values indicating greater lipid content) and optical coherence tomography-derived minimal fibrous cap thickness (smaller values indicating thin-capped, vulnerable plaques) from baseline to week 52. Results: Among 300 randomized patients (mean [SD] age, 58.5 [9.7] years; 56 [18.7%] women; mean [SD] low-density lipoprotein cholesterol level, 152.4 [33.8] mg/dL), 265 (88.3%) underwent serial IVUS imaging in 537 arteries. At 52 weeks, mean change in percent atheroma volume was -2.13% with alirocumab vs -0.92% with placebo (difference, -1.21% [95% CI, -1.78% to -0.65%], P < .001). Mean change in maximum lipid core burden index within 4 mm was -79.42 with alirocumab vs -37.60 with placebo (difference, -41.24 [95% CI, -70.71 to -11.77]; P = .006). Mean change in minimal fibrous cap thickness was 62.67 µm with alirocumab vs 33.19 µm with placebo (difference, 29.65 µm [95% CI, 11.75-47.55]; P = .001). Adverse events occurred in 70.7% of patients treated with alirocumab vs 72.8% of patients receiving placebo. Conclusions and Relevance: Among patients with acute myocardial infarction, the addition of subcutaneous biweekly alirocumab, compared with placebo, to high-intensity statin therapy resulted in significantly greater coronary plaque regression in non-infarct-related arteries after 52 weeks. Further research is needed to understand whether alirocumab improves clinical outcomes in this population. Trial Registration: ClinicalTrials.gov Identifier: NCT03067844.

BACKGROUND: The risk for cardiovascular adverse events after acute myocardial infarction (AMI) remains high despite potent medical treatment including low-density lipoprotein cholesterol (LDL-C) lowering with statins. Proprotein convertase subtilisin/kexin type 9 (PCSK9) antibodies substantially reduce LDL-C when added to statin. Alirocumab, a monoclonal antibody to PCSK9, reduces major adverse cardiovascular events after AMI. The effects of alirocumab on coronary atherosclerosis including plaque burden, plaque composition and fibrous cap thickness in patients presenting with AMI remains unknown. AIMS: To determine the effect of LDL-C lowering with alirocumab on top of high-intensity statin therapy on intravascular ultrasound (IVUS)-derived percent atheroma volume (PAV), near-infrared spectroscopy (NIRS)-derived maximum lipid core burden index within 4 mm (maxLCBI4 mm) and optical coherence tomography (OCT)-derived fibrous cap thickness (FCT) in patients with AMI. METHODS: In this multicenter, double-blind, placebo-controlled trial, 300 patients with AMI (ST-elevation or non-ST-elevation myocardial infarction) were randomly assigned to receive either biweekly subcutaneous alirocumab (150 mg) or placebo beginning <24 hours after the acute event as add-on therapy to rosuvastatin 20 mg. Patients undergo serial IVUS, NIRS and OCT in the two non-infarct related arteries at baseline (at the time of treatment of the culprit lesion) and at 52 weeks. The primary endpoint, change in IVUS-derived PAV, and the powered secondary endpoints, change in NIRS-derived maxLCBI4 mm, and OCT-derived minimal FCT, will be assessed 52 weeks post randomization. SUMMARY: The PACMAN-AMI trial will determine the effect of alirocumab on top of high-intensity statin therapy on high-risk coronary plaque characteristics as assessed by serial, multimodality intracoronary imaging in patients presenting with AMI. CLINICAL TRIAL REGISTRATION: NCT03067844.

OBJECTIVES: We aimed to assess the ischemic and bleeding risks of single antiplatelet therapy (SAPT) with prasugrel compared with standard dual antiplatelet therapy (DAPT) (aspirin plus clopidogrel for 1 year) in patients with chronic coronary syndrome (CCS) treated with new generation drug-eluting stents (DES). BACKGROUND: To date, data on SAPT with potent P2Y12 inhibitors in the absence of aspirin immediately after PCI are limited. METHODS: Between January 2009 and November 2019, all CCS patients undergoing percutaneous coronary intervention (PCI) enrolled to the Bern PCI registry were considered for analysis. We performed propensity score matching in a 1:4 fashion to compare patients who received SAPT with prasugrel versus standard DAPT. The primary ischemic endpoint was a composite of cardiovascular death, myocardial infarction, and stroke and the primary bleeding endpoint was BARC 3 or 5 bleeding, both assessed at 1 year. RESULTS: After propensity score matching, the final study population consisted of 225 patients with SAPT and 889 with DAPT. There was no significant difference in rates of the primary ischemic (5.2% vs. 4.2%, p = .50) or the primary bleeding (1.5% vs. 2.0%, p = .60) endpoints between groups. SAPT was not associated with an increased risk of definite stent thrombosis (0.9% vs. 0.8%, p = .83). CONCLUSIONS: Among selected CCS patients undergoing PCI with DES, SAPT with prasugrel was not associated with an excess of ischemic events compared with standard DAPT. No difference in bleeding was observed either. The results may serve as the basis for larger trials assessing the potential benefits and risks of SAPT.

BACKGROUND: The high mortality of acute myocardial infarction (AMI) with cardiogenic shock (i.e., Killip class IV AMI) remains a challenge in emergency cardiovascular care. This study aimed to examine institutional factors, including the number of JCS board-certified members, that are independently associated with the prognosis of Killip class IV AMI patients.MethodsâandâResults:In the Japanese registry of all cardiac and vascular diseases-diagnosis procedure combination (JROAD-DPC) database (years 2012-2016), the 30-day mortality of Killip class IV AMI patients (n=21,823) was 42.3%. Multivariate analysis identified age, female sex, admission by ambulance, deep coma, and cardiac arrest as patient factors that were independently associated with higher 30-day mortality, and the numbers of JCS board-certified members and of intra-aortic balloon pumping (IABP) cases per year as institutional factors that were independently associated with lower mortality in Killip class IV patients, although IABP was associated with higher mortality in Killip classes I-III patients. Among hospitals with the highest quartile (≥9 JCS board-certified members), the 30-day mortality of Killip class IV patients was 37.4%. CONCLUSIONS: A higher numbers of JCS board-certified members was associated with better survival of Killip class IV AMI patients. This finding may provide a clue to optimizing local emergency medical services for better management of AMI patients in Japan.

Although antiarrhythmic drugs have long been used for the suppression of various types of arrhythmias, their prior use before the onset of ventricular arrhythmia with hemodynamic collapse and the effect on prognosis is not well known. Data from 1004 consecutive patients with cardiovascular shock in the Japanese Circulation Society's Shock Registry were analyzed. Eighty-four cases of ventricular arrhythmia-induced shock and ROSC (return of spontaneous circulation) were divided into the prior amiodarone or ß-blockers use group (Aß group, n = 27) and the non-amiodarone and non-ß-blockers use group (non-Aß group; n = 57) based on treatment before the onset of those arrhythmias. Clinical outcomes related to hemodynamic collapse such as OHCA (out-of-hospital cardiovascular arrest) was less in the Aß group [Aß group, 11/26 (42%) vs. non-Aß group, 41/56 (73%); p = 0.007]. Similarly, syncope was less common in the Aß group than in the non-Aß group [Aß group 4/27 (15%) vs. non-Aß group 27/57 (47%); p = 0.004]. Furthermore, prior amiodarone or ß-blockers use before the onset of ventricular arrhythmias was strongly associated with both survival at discharge (odds ratio 3.19; 95% confidence interval 1.06-9.67; p = 0.040) and neurological outcomes at discharge (odds ratio 3.96; 95% confidence interval 1.32-11.85; p = 0.014) based on multivariate logistic regression analysis. Prior amiodarone or ß-blockers use before the onset of malignant ventricular arrhythmia and maintaining appropriate blood concentrations in advance is associated with a good survival rate and better neurological outcomes after recovery from ventricular arrhythmia with hemodynamic collapse.

Intracoronary imaging - an essential tool on the way to an individualized therapy of coronary artery disease? Abstract. Since decades, coronary angiography is the standard method to assess coronary anatomy and guide percutaneous coronary intervention. However, coronary angiography is limited to the lumen and a resolution of 200 - 300 micrometers. Thus, anything beyond is not detectable. Intracoronary imaging methods by means of intravascular ultrasound (IVUS) and particularly optical coherence tomography (OCT), provide incremental effects on coronary diagnostics and therapeutic decisions. Plaque burden and -composition (lipid, fibrous, calcific tissue, intramural hematoma), small intraluminal structures (thrombus), and implanted stents are uniquely detectable by intracoronary imaging. The use of these techniques inevitably leads to improved precision in coronary diagnostics and optimization of stent implantation.

PURPOSE: To report the 1-year outcomes of a single-center, all-comers registry aimed to assess effectiveness and safety of endovascular revascularization for atherosclerotic erectile dysfunction (ED) in an unselected patient cohort. MATERIALS AND METHODS: Between April 2016 and October 2017, 50 consecutive patients (mean age 59.6±10.3 years) underwent endovascular revascularization for ED owing to >50% stenosis in 82 erection-related arteries. Patients were treated by means of standard balloon angioplasty (16%), drug-coated balloon angioplasty (27%), or drug-eluting stent (55%) implantation. The primary feasibility outcome measure was the incidence of a minimum clinically relevant improvement of ≥4 in the 6-question International Index of Erectile Function Questionnaire (IIEF-6) score at 12 months. Clinical effectiveness was improvement in erectile function as quantified in the mean difference (MD) of the IIEF-15 score at 3 and 12 months as well as the mean changes in IIEF-15 questions 3 and 4. RESULTS: Procedure success was achieved in 49 (98%) of 50 patients. At 12 months, 30 (65%) of 46 patients achieved a minimum clinically relevant improvement in the IIEF-6 score. The overall IIEF-15 score, as well as scores for questions 3 and 4, improved in 32 (65%) of 49 patients, 28 (57%) of 49 patients, and 29 (60%) of 48 patients, respectively. Change in the overall IIEF-15 score at 12 months was consistent among subgroups, except for elderly patients [MD -5.0 (95% CI -9.7 to -0.2), p=0.041] and those with hypertension [MD -11.0 (95% CI -20.5 to -1.5), p=0.025], who showed less improvement. CONCLUSION: Endovascular revascularization was safe and efficacious in the majority of ED patients through 1 year.

BACKGROUND: Consciousness disturbance is one of the major clinical signs associated with shock state, but its prognostic value has not been previously evaluated in cardiovascular shock patients. We aimed to evaluate the prognostic value of neurological status for 30-day mortality in cardiovascular shock patients without out-of-hospital cardiac arrest (OHCA). MethodsâandâResults: Patients with out-of-hospital onset cardiovascular shock were recruited from the Japanese Circulation Society Shock Registry. Neurological status upon hospital arrival was evaluated using the Japan Coma Scale (JCS). Patients were divided into 4 groups according to the JCS: alert, JCS 0; awake, JCS 1-3 (not fully alert but awake without any stimuli); arousable, JCS 10-30 (arousable with stimulation); and coma JCS 100-300 (unarousable). The primary endpoint was 30-day all-cause death. In total, 700 cardiovascular shock patients without OHCA were assessed. The coma group was associated with a higher incidence of 30-day all-cause death compared with other groups (alert, 15.3%; awake, 24.4%; arousable, 36.8%; coma, 48.5%, P<0.001). Similar trends were observed in etiologically divergent subgroups (acute coronary syndrome, non-ischemic arrhythmia, and aortic disease). On multivariate Cox regression analysis, arousable (hazard ratio [HR], 1.82; 95% CI: 1.16-2.85, P=0.009) and coma (HR, 2.72; 95% CI: 1.76-4.22, P<0.001) (reference: alert) independently predicted 30-day mortality. CONCLUSIONS: Neurological status upon hospital arrival was useful to predict 30-day mortality in cardiovascular shock patients without OHCA.

The exercise ankle-brachial index (ABI) helps diagnose lower extremity peripheral artery disease (PAD). Patients with comorbidities may be unable to perform treadmill exercise, the most common stress loading test. While the active pedal plantar flexion (APP) test using the leg loader, simple and easy stress loading device, could be an alternative, there are no data comparing the leg loader and treadmill exercise. Therefore, we aimed to compare APP using the leg loader and treadmill exercise to evaluate PAD. A total of 27 patients (54 limbs) diagnosed with PAD with intermittent claudication and considered for angiography and/or endovascular treatment were recruited prospectively, and both the leg loader and treadmill were performed. There was a strong correlation (r = 0.925, p < 0.001) between the leg loader ABI and treadmill ABI; however, the decrease rate of the leg loader ABI was significantly less than that of treadmill ABI (14.0% [5.6, 30.1] vs. 25.8% [6.1, 53.1], p < 0.001). The number of patients who terminated the exercise prematurely due to dyspnea was four during the treadmill and zero during the leg loader. There was a good correlation between the leg loader ABI and treadmill ABI. Although leg loader, a simple, safe, and easy method, could be an alternative to diagnose PAD, further studies are needed to evaluate the diagnostic value of the leg loader in patients with borderline ABI or those unable to perform the treadmill.

Cardiogenic shock frequently leads to death even with intensive treatment. Although the leading cause of cardiogenic shock is acute coronary syndrome (ACS), the clinical characteristics and the prognosis of ACS with cardiogenic shock in the present era still remain to be elucidated. We analyzed clinical characteristics and predictors of 30-day mortality in ACS with cardiogenic shock in Japan. The Japanese Circulation Society Cardiovascular Shock registry was a prospective, observational, multicenter, cohort study. Between May 2012 and June 2014, 495 ACS patients with cardiogenic shock were analyzed. The primary endpoint was 30-day all-cause mortality. The median [interquartile range; IQR] age was 71.0 [63.0, 80.0] years. The median [IQR] value of systolic blood pressure (SBP) and heart rate were 75.0 [50.0, 86.5] mm Hg and 65.0 [38.0, 98.0] bpm, respectively. Multivariable analysis showed an odds ratio (OR) of 4.76 (confidence intervals; CI 1.97-11.5, p < 0.001) in the lowest SBP category (< 50 mm Hg) for SBP ≥ 90 mm Hg. Moreover, age per 10 years increase (OR 1.38, CI 1.18-1.61, p = 0.002), deep coma (OR 3.49, CI 1.94-6.34, p < 0.001), congestive heart failure (OR 3.81, CI 2.04-7.59, p < 0.001) and left main trunk disease (LMTD) (OR 2.81, CI 1.55-5.10, p < 0.001) were independent predictors. Severe hypotension, older age, deep coma, congestive heart failure, and LMTD were independent unfavorable factors in ACS complicated by cardiogenic shock in Japan. A prompt assessment of high-risk patients referring to those predictors in emergency room could lead to appropriate treatment without delay.

BACKGROUND: Hyperventilation with a subsequent breath-hold has been successfully used as a non-pharmacological vasoactive stimulus to induce changes in myocardial oxygenation. The purpose of this pilot study was to assess if this maneuver is feasible in patients with multi-vessel coronary artery disease (CAD), and if it is effective at detecting coronary artery stenosis > 50% determined by quantitative coronary angiography (QCA). METHODS: Twenty-six patients with coronary artery stenosis (QCA > 50% diameter stenosis) underwent a contrast-free cardiovascular magnetic resonance (CMR) exam in the time interval between their primary coronary angiography and a subsequent percutaneous coronary intervention (PCI, n = 24) or coronary artery bypass (CABG, n = 2) revascularization procedure. The CMR exam involved standard function imaging, myocardial strain analysis, T2 mapping, native T1 mapping and oxygenation-sensitive CMR (OS-CMR) imaging. During OS-CMR, participants performed a paced hyperventilation for 60s followed by a breath-hold to induce a vasoactive stimulus. Ten healthy subjects underwent the CMR protocol as the control group. RESULTS: All CAD patients completed the breathing maneuvers with an average breath-hold duration of 48 ± 23 s following hyperventilation and without any complications or adverse effects. In comparison to healthy subjects, CAD patients had a significantly attenuated global myocardial oxygenation response to both hyperventilation (- 9.6 ± 6.8% vs. -3.1 ± 6.5%, p = 0.012) and apnea (11.3 ± 6.1% vs. 2.1 ± 4.4%, p < 0.001). The breath-hold maneuver unmasked regional oxygenation differences in territories subtended by a stenotic coronary artery in comparison to remote territory within the same patient (0.5 ± 3.8 vs. 3.8 ± 5.3%, p = 0.011). CONCLUSION: Breathing maneuvers in conjunction with OS-CMR are clinically feasible in CAD patients. Furthermore, OS-CMR demonstrates myocardial oxygenation abnormalities in regional myocardium related to CAD without the use of pharmacologic vasodilators or contrast agents. A larger trial appears warranted for a better understanding of its diagnostic utility. TRIAL REGISTRATION: Clinical Trials Identifier: NCT02233634 , registered 8 September 2014.

BACKGROUND: The geriatric nutritional risk index (GNRI) is a simple and objective nutritional assessment tool for elderly patients. Lower GNRI values are associated with a worse prognosis in patients with heart failure (HF). However, few data are available regarding the prognostic effect of the GNRI value for risk stratification in patients at risk for HF.MethodsâandâResults:We retrospectively investigated 1,823 consecutive patients at risk for HF (Stage A/B) enrolled in the IMPACT-ABI Study. GNRI on admission was calculated as follows: 14.89×serum albumin (g/dL)+41.7×body mass index/22. Patients were divided into 2 groups according to the median GNRI value (107.1). The study endpoint was a composite of cardiovascular (CV) events, including CV death and hospitalization for worsening HF. Over a 4.7-year median follow-up, CV events occurred in 130 patients. In the Kaplan-Meier analysis, patients with low GNRI (<107.1, n=904) showed worse prognoses than those with high GNRI (≥107.1, n=919) (20.2% vs. 12.4%, P<0.001). In the multivariable Cox proportional hazards analysis, low GNRI was significantly associated with the incidence of CV events (hazard ratio: 1.48, 95% confidence interval: 1.02-2.14; P=0.040). CONCLUSIONS: The simple and practical assessment of GNRI may be useful for predicting CV events in patients with Stage A/B HF.

Brachial-ankle pulse wave velocity (baPWV) is known as a significant predictor of cardiovascular events. However, the previous studies have not considered age, which can affect the baPWV value. We evaluated the predictive value of baPWV for cardiovascular events in various age groups. From January 2005 to December 2012, all patients admitted to our department with any cardiovascular disease and underwent ankle-brachial index (ABI) measurement were enrolled in the IMPACT-ABI registry. The primary endpoints included major adverse cardiovascular events (MACE; cardiovascular death, myocardial infarction, and stroke). Of the 3131 patients enrolled, 2554 were included in the analysis, whereas 577 were excluded due to missing baPWV data, ABI ≤0.9 and/or >1.4, and the previous endovascular therapy and/or surgical treatment for peripheral artery disease. Patients were divided according to age 30-59 years (n = 580), 60-69 years (n = 730), 70-79 years (n = 862), and ≥80 years (n = 330). The cumulative incidence of MACE through 5 year was significantly higher in the high baPWV group (>1644 cm/s) than in the low baPWV group (≤1644 cm/s; 8.7 vs. 4.6%; log-rank: p < 0.001). However, among the age groups, only the 30-59-year group showed a significant difference in MACE incidence between those with high and low baPWV (7.0 vs. 0.9%; log-rank: p = 0.001). In conclusion, the baPWV could serve as a useful marker to predict cardiovascular events, particularly among younger patients.

The ankle brachial index (ABI) is regarded as a predictor of future cardiovascular events. However, the relationship between ABI and incident heart failure (HF) in patients without previous HF is poorly understood. This study aimed to assess the prognostic value of ABI for incident HF in patients without previous HF. The IMPACT-ABI study was a retrospective, single-center, cohort study that enrolled and measured ABI in 3131 patients hospitalized for cardiovascular disease between January 2005 and December 2012. From this cohort, 307 patients were excluded because of previous HF and high (>1.4) ABI. The remaining 2824 patients were stratified into three groups: low ABI (≤0.9), borderline ABI (0.91-0.99), and normal ABI (1.0-1.4). The primary endpoint was hospitalization for HF. Over a mean 4.8-year follow-up, 105 cases of HF occurred. The cumulative incidence of HF was significantly higher in patients with low and borderline ABIs than in those with normal ABI (19.3 vs. 21.0 vs. 10.4 %, log rank P <0.001). In multivariate Cox proportional hazard analysis, low ABI and borderline ABI were independent predictors of incident HF [hazard ratio (HR) 3.00; 95 % confidence interval (CI) 1.70-5.28; P < 0.001 and HR 2.68; 95 % CI 1.35-5.34; P = 0.005, respectively]. In conclusion, low and borderline ABI were strong predictors for future incident HF in patients without previous HF.
