Treatment and outcomes of patients with chronic lung disease and acute myocardial infarction: Insights from the nationwide AMIS plus registry. Eur J Clin Invest 2024; 54:e14193. [PMID: 38481088 DOI: 10.1111/eci.14193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 02/25/2024] [Accepted: 02/25/2024] [Indexed: 05/15/2024]
Abstract
BACKGROUND Limited data are available on patients with chronic lung disease (CLD) presenting with acute myocardial infarction (AMI). We aimed to analyse baseline characteristics, treatment and outcome of those patients enrolled in the Swiss nationwide prospective AMIS Plus registry. METHODS All AMI patients enrolled between January 2002 and December 2021 with data on CLD, as defined in the Charlson Comorbidity Index, were included. The primary endpoints were in-hospital mortality and major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, reinfarction and cerebrovascular events. Baseline characteristics, in-hospital treatments and outcomes were analysed using descriptive statistics and logistic regression. RESULTS Among 53,680 AMI patients enrolled during this time, 5.8% had CLD. Compared with patients without CLD, CLD patients presented more frequently with non-ST-elevation myocardial infarction (MI) and type 2 MI (12.8% vs. 6.5%, p < 0.001). With respect to treatment, CLD patients were less likely to receive P2Y12 inhibitors (p < 0.001) and less likely to undergo percutaneous coronary interventions (68.7% vs. 82.5%; p < 0.001). In-hospital mortality declined in AMI patients with CLD over time (from 12% in 2002 to 7.3% in 2021). Multivariable regression analysis showed that CLD was an independent predictor for MACCE (adjusted OR was 1.28 [95% CI 1.07-1.52], p = 0.006). CONCLUSION Patients with CLD and AMI were less likely to receive evidence-based pharmacologic treatments, coronary revascularization and had a higher incidence of MACCE during their hospital stay compared to those without CLD. Over 20 years, in-hospital mortality was significantly reduced in AMI patients, especially in those with CLD.

Association between chronic obstructive pulmonary disease and cardiovascular disease in adults aged 40 years and above: data from NHANES 2013-2018. BMC Pulm Med 2023; 23:318. [PMID: 37653498 PMCID: PMC10472556 DOI: 10.1186/s12890-023-02606-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 08/14/2023] [Indexed: 09/02/2023] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) are two major age-related diseases prevalent in the elderly. However, it is unclear whether there is a higher prevalence of one or more CVDs in COPD patients compared to those without COPD, and the magnitude of this increased prevalence. METHODS This population-based cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (NHANES) 2013-2018 among American adults aged 40 years and above. Multivariable logistic regression models (including unadjusted model, minimally adjusted model, and fully adjusted model) were conducted to investigate the association between COPD and the prevalence of one or more CVDs, including coronary heart disease, heart failure, angina pectoris, heart attack, diabetes, and stroke. RESULTS This study included 11,425 participants, consisting of 661 participants with COPD and 10,764 participants without COPD. COPD patients had a significantly higher prevalence of CVD than those without COPD (59.6% vs. 28.4%). After adjusting for covariates, COPD was significantly associated with the prevalence of one CVD (OR = 2.2, 95% CI = 1.6-3.0, p < 0.001), two or more CVDs (OR = 3.3, 95% CI = 2.2-5.0, p < 0.001), and three or more CVDs (OR = 4.3, 95% CI = 2.9-6.5, p < 0.001). CONCLUSIONS Patients with COPD have a higher prevalence of one or more CVDs compared with those without COPD. Our findings highlight the importance of CVD prevention and management in patients with COPD.

Impact of chronic obstructive pulmonary disease on short-term outcome in patients with ST-elevation myocardial infarction during COVID-19 pandemic: insights from the international multicenter ISACS-STEMI registry. Respir Res 2022; 23:207. [PMID: 35971173 PMCID: PMC9376902 DOI: 10.1186/s12931-022-02128-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Accepted: 05/02/2022] [Indexed: 11/10/2022] Open
Abstract
Background Chronic obstructive pulmonary disease (COPD) is projected to become the third cause of mortality worldwide. COPD shares several pathophysiological mechanisms with cardiovascular disease, especially atherosclerosis. However, no definite answers are available on the prognostic role of COPD in the setting of ST elevation myocardial infarction (STEMI), especially during COVID-19 pandemic, among patients undergoing primary angioplasty, that is therefore the aim of the current study. Methods In the ISACS-STEMI COVID-19 registry we included retrospectively patients with STEMI treated with primary percutaneous coronary intervention (PCI) between March and June of 2019 and 2020 from 109 high-volume primary PCI centers in 4 continents. Results A total of 15,686 patients were included in this analysis. Of them, 810 (5.2%) subjects had a COPD diagnosis. They were more often elderly and with a more pronounced cardiovascular risk profile. No preminent procedural dissimilarities were noticed except for a lower proportion of dual antiplatelet therapy at discharge among COPD patients (98.9% vs. 98.1%, P = 0.038). With regards to short-term fatal outcomes, both in-hospital and 30-days mortality occurred more frequently among COPD patients, similarly in pre-COVID-19 and COVID-19 era. However, after adjustment for main baseline differences, COPD did not result as independent predictor for in-hospital death (adjusted OR [95% CI] = 0.913[0.658–1.266], P = 0.585) nor for 30-days mortality (adjusted OR [95% CI] = 0.850 [0.620–1.164], P = 0.310). No significant differences were detected in terms of SARS-CoV-2 positivity between the two groups. Conclusion This is one of the largest studies investigating characteristics and outcome of COPD patients with STEMI undergoing primary angioplasty, especially during COVID pandemic. COPD was associated with significantly higher rates of in-hospital and 30-days mortality. However, this association disappeared after adjustment for baseline characteristics. Furthermore, COPD did not significantly affect SARS-CoV-2 positivity. Trial registration number: NCT 04412655 (2nd June 2020).

Effects of COPD on Left Ventricular and Left Atrial Deformation in Patients with Acute Myocardial Infarction: Strain Analysis Using Speckle-Tracking Echocardiography. J Clin Med 2022; 11:jcm11071917. [PMID: 35407524 PMCID: PMC8999583 DOI: 10.3390/jcm11071917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 03/23/2022] [Accepted: 03/28/2022] [Indexed: 12/04/2022] Open
Abstract
Myocardial strain analysis, which describes myocardial deformation (shortening or lengthening), provides more detailed information about left ventricular (LV) and atrial (LA) functions than conventional echocardiography and delivers prognostic information. To analyze the effects of COPD on left heart function upon acute myocardial infarction (AMI), consecutive AMI patients were retrospectively screened, and patients were included if a post-AMI echocardiography and results of recent pulmonary function tests (PFTs) were available. Strain analysis was performed by a cardiologist who was blinded to clinical information. Overall, 109 AMI patients were included (STEMI: 38%, non-STEMI: 62%). COPD patients (41%) had significantly more impaired LV “global-longitudinal-strain” (LV-GLS) compared to non-COPD patients (−15 ± 4% vs. −18 ± 4%; p < 0.001, respectively), even after adjusting for LV-ejection-fraction (LVEF) and age (mean estimated difference: 1.7%, p = 0.009). Furthermore, COPD patients had more impaired LA strain (LAS) than non-COPD patients in all cardiac cycle phases (estimated mean differences after adjusting for LVEF and age: during reservoir phase: −7.5% (p < 0.001); conduit phase: 5.5% (p < 0.001); contraction phase: 1.9% (p = 0.034)). There were no correlations between PFT variables and strain values. In conclusion, the presence of COPD was associated with more impaired LV and LA functions after AMI, as detected by strain analysis, which was independent of age, LVEF, and PFT variables.

Predictors of in-hospital mortality in diabetic patients with non-ST-elevation myocardial infarction. Egypt Heart J 2022; 74:20. [PMID: 35347479 PMCID: PMC8960521 DOI: 10.1186/s43044-022-00256-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Accepted: 03/15/2022] [Indexed: 12/05/2022] Open
Abstract
Background There have been little data about the additive effects of coronary risk factors on mortality in diabetic patients presenting with non-ST-segment elevation myocardial infarction (NSTEMI). This study aimed to evaluate the predictors of mortality in diabetic patients presenting with NSTEMI. All patients admitted to Tehran Heart Center (THC) with a confirmed diagnosis of NSTEMI and a history of diabetes mellitus (DM) type 2 between September 2003 and April 2017 were included. Clinical characteristics and paraclinical data such as lipid profiles, creatinine, hemoglobin, and hemoglobin A1C (HbA1C) were evaluated in these patients to predict in-hospital mortality. The approach for model calibration was a logistic regression with the backward elimination method. Results Of a total of 9158 patients with non-ST-segment elevation myocardial infarction, 3133 had diabetes mellitus type 2 and met our criteria to enter the final analysis. In the multivariable analysis, age, chronic obstructive pulmonary disease, and a severely reduced left ventricular ejection fraction (LVEF) significantly increased the rate of in-hospital mortality, whereas mildly and moderately reduced left ventricular ejection fraction did not increase the rate of mortality. Conclusions Age, chronic obstructive pulmonary disease (COPD), and severely reduced LVEF (< 30%) independently increased in-hospital mortality in our diabetic patients with a confirmed diagnosis of NSTEMI. Severely reduced LVEF had the strongest relationship with in-hospital mortality, whereas the mean HbA1C level and the type of DM management exerted no significant effect on in-hospital mortality.

Abstract
The use of mechanical circulatory devices to support high-risk elective percutaneous coronary intervention (PCI) has become more common as the group of patients considered inoperable or high risk for surgical revascularization has grown. Most of the data examining outcomes in high-risk PCI are observational and retrospective. Limited prospective randomized studies have been unable to show improved clinical outcomes with routine mechanical circulatory support (MCS) in patients with a high burden of coronary artery disease and reduced ejection fraction. The role for MCS in high-risk PCI continues to evolve as understanding of the appropriate groups for this therapy evolves.

Abstract
The frequency, characteristics and outcomes of acute myocardial infarction (AMI) during exacerbation of chronic obstructive pulmonary disease (COPD) are unknown. Adult patients hospitalized with a principle diagnosis of acute COPD exacerbation were identified using retrospective analysis of the Nationwide Inpatient Sample (NIS) from 2003 to 2016. Patients were stratified into 2-groups with and without a secondary diagnosis of AMI. The study's endpoints were in-hospital morbidity, mortality, and resource utilization. We also assessed the impact of invasive management strategy on the same end-points. We included 6 894 712 hospitalizations, of which 56 515 (0.82%) were complicated with AMIs. Patients with AMI were older, and had higher prevalence of known coronary disease (48.9% vs. 27.4%), atrial fibrillation (23.3% vs. 15.2%), heart failure (47.8% vs. 26.2%), and anemia (20.7% vs. 14.8%) (p < 0.001). Rates of oxygen dependence were similar (16.3% vs. 16.1%, p = 0.24). In 56 486 propensity-matched pairs of patients with and without AMI, mortality was higher in the AMI group (12.1% vs. 2.1%, p < 0.001). Rates of major morbidities, non-home discharge, and cost were all higher in the AMI group. A minority (18.1%) of patients with AMI underwent invasive assessment, and those had lower in-hospital mortality before (4.9% vs. 13.8%) and after (5.0% vs. 10.0%) propensity-score matching (p < 0.001). This lower mortality persisted in a sensitivity analysis accounting for immortal time bias. AMI complicates ∼1% of patients admitted with acute COPD exacerbation, and those have worse outcomes than those without AMI. Invasive management for secondary AMI during acute COPD exacerbation may be associated with improved outcomes but is utilized in <20% of patients.

Impact of comorbidities on peak troponin levels and mortality in acute myocardial infarction. Heart 2020; 106:677-685.

Abstract
OBJECTIVES To characterise peak cardiac troponin levels, in patients presenting with acute myocardial infarction (AMI), according to their comorbid condition and determine the influence of peak cardiac troponin (cTn) levels on mortality. METHODS We included patients with the first admission for AMI in the UK. We used linear regression to estimate the association between eight common comorbidities (diabetes mellitus, previous angina, peripheral arterial disease, previous myocardial infarction (MI), chronic kidney disease (CKD), cerebrovascular disease, chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD)) and peak cTn. Peak cTn levels were adjusted for age, sex, smoking status and comorbidities. Logistic regression and restricted cubic spline models were employed to investigate the association between peak cTn and 180-day mortality for each comorbidity. RESULTS 330 367 patients with ST elevation myocardial infarction and non-ST elevation myocardial infarction were identified. Adjusted peak cTn levels were significantly higher in patients with CKD (adjusted % difference in peak cTnT for CKD=42%, 95% CI 13.1 to 78.4) and significantly lower for patients with COPD, previous angina, previous MI and CHF when compared with patients without the respective comorbidities (reference group) (cTnI; COPD=-21.7%, 95% CI -29.1 to -13.4; previous angina=-24.2%, 95% CI -29.6 to -8.3; previous MI=-13.5%, 95% CI -20.6 to -5.9; CHF=-28%, 95% CI -37.2 to -17.6). Risk of 180-day mortality in most of the comorbidities did not change substantially after adjusting for peak cTn. In general, cTnI had a stronger association with mortality than cTnT. CONCLUSIONS In this nationwide analysis of patients presenting with AMI, comorbidities substantially influenced systemic concentrations of peak cTn. Comorbid illness is a significant predictor of mortality regardless of peak cTn levels and should be taken into consideration while interpreting cTn both as a diagnostic and prognostic biomarker.

Early Invasive Versus Ischemia-Guided Strategy in Non-ST-Segment Elevation Acute Coronary Syndrome With Chronic Obstructive Pulmonary Disease: A National Inpatient Sample Analysis. Angiology 2019; 71:372-379.

Abstract
Chronic obstructive pulmonary disease (COPD) is a risk factor for non-ST-segment elevation-acute coronary syndromes (NSTE-ACS). Whether early invasive strategy (EIS) or ischemia-guided strategy (IGS) confers better outcomes in NSTE-ACS with COPD is largely unknown. Nationwide Inpatient Sample database of the United States was queried from 2010 to 2015 to identify NSTE-ACS with and without COPD. Early invasive strategy was defined as coronary angiogram with or without revascularization on admission day 0 or 1, whereas IGS included patients who did not receive EIS. Standardized morbidity ratio weight was used to calculate the adjusted odds ratio. A total of 228 175 NSTE-ACS admissions with COPD were identified of which 34.0% received EIS. In-hospital mortality was lower with EIS in patients with COPD (3.1% vs 5.5%, adjusted odds ratio 0.57, 95% confidence interval 0.50-0.63) compared to IGS, but the magnitude of mortality reduction observed in EIS in patients with COPD was less compared to non-COPD patients (P interaction = .02). Length of stay was shorter (4.2 vs 4.7 days, P < .0001) but the cost was higher (US$23 804 vs US$18 533, P < .0001) in EIS in COPD. Early invasive strategy resulted in lower in-hospital mortality and marginally shorter length of stay but higher hospitalization cost in NSTE-ACS with COPD.

Abstract
BACKGROUND Non-ST-segment elevation myocardial infarction (NSTEMI) comprises the majority of MI worldwide, yet mortality remains high. Management of NSTEMI is relatively delayed and heterogeneous compared with the "time is muscle" approach to ST-segment elevation MI, though it is unknown to what extent comorbid conditions drive NSTEMI mortality. OBJECTIVES We sought to quantify mortality due to MI versus comorbid conditions in patients with NSTEMI. METHODS Participants of the ARIC (Atherosclerosis Risk in Communities) study cohort ages 45 to 64 years, who developed incident NSTEMI were identified and incidence-density matched to participants who did not experience an MI by age group, sex, race, and study community. We estimated hazard ratios for all-cause mortality, comparing those who developed NSTEMI to those who did not experience an MI. RESULTS ARIC participants with incident NSTEMI were more likely at baseline to be smokers, have diabetes and renal dysfunction, and take blood pressure or cholesterol-lowering medications than were participants who did not have an MI. Over one-half of participants experiencing NSTEMI died over a median follow-up of 8.4 years; incident NSTEMI was associated with 30% higher risk of mortality after adjusting for comorbid conditions (hazard ratio: 1.30; 95% confidence interval: 1.11 to 1.53). CONCLUSIONS NSTEMI confers a significantly higher mortality hazard beyond what can be attributed to comorbid conditions. More consistent and effective strategies are needed to reduce mortality in NSTEMI amid comorbid conditions.

Presentation, management and mortality after a first MI in people with and without asthma: A study using UK MINAP data. Chron Respir Dis 2018; 15:60-70.

Abstract
Asthma has been associated with a higher incidence of myocardial infarction (MI), higher prevalence of MI risk factors and higher burden of cardiovascular diseases. However, detailed associations between the presentation and initial management at the time of MI and post-MI outcomes in people with asthma compared to the general population have not been studied. A total of 300,161 people were identified with a first MI over the period 2003-2013 in the Myocardial Ischaemia National Audit Project database, of whom 8922 (3%) had asthma. Logistic regression was used to compare presentation, in-hospital care, in-hospital and 180-day post-discharge all-cause mortality in people with and without asthma adjusting for demographics and comorbidities, diagnosis on arrival and secondary prevention. People with asthma were more likely to have a delay in their MI diagnosis following an STEMI (ST-elevation myocardial infarction; odds ratio (OR) 1.38, confidence interval CI 1.06-1.79) but not an nSTEMI (non-ST-elevation myocardial infarction; OR 1.04, CI 0.92-1.17) compared to people without asthma and a delay in reperfusion (OR 1.19, CI 1.09-1.30) following an STEMI. They were much less likely to be discharged on a beta blocker following an STEMI or nSTEMI (OR 0.24, CI 0.21-0.28 and OR 0.27, CI 0.24-0.30, respectively). There was no difference in in-hospital or 180-day mortality (OR 0.98, CI 0.59-1.62 and OR 0.99, CI 0.72-1.36) following an STEMI or nSTEMI (OR 0.89, CI 0.47-1.68 and OR 1.05, CI 0.85-1.28). Although people with asthma were more likely to have a delay in diagnosis following an STEMI but not an nSTEMI compared to the general population, were more likely to have a delay in reperfusion therapy and were much less likely to receive beta blockers following an STEMI or nSTEMI, there was no difference in the prescriptions of other secondary prevention medications. None of the differences in presentation or management were associated with an increase in all-cause in-hospital or 180-day mortality in people with asthma compared to the general population.

Abstract
Background Understanding the relative risk of cardiovascular versus noncardiovascular death is important for designing clinical trials. These risks may differ depending on patient age, sex, and type of acute coronary syndrome (ACS). Methods and Results IMPROVE‐IT (Improved Reduction of Outcomes: Vytorin Efficacy International Trial) was a randomized controlled trial of simvastatin plus either ezetimibe or placebo following stabilized ACS. Cause of death was adjudicated by an independent committee. We compared the cumulative incidence of cardiovascular and noncardiovascular death for patients with unstable angina/non‐ST‐segment elevation myocardial infarction (UA/NSTEMI) and ST‐segment elevation myocardial infarction (STEMI), in those <65 and ≥65 years old, and males and females, over 7 years of follow‐up. Of 18 131 patients, the presenting event was STEMI for 5190 (29%) and UA/NSTEMI for 12 941 (71%); 10 173 (56%) patients were <65 years old and 7971 (44%) were ≥65 years old at presentation. UA/NSTEMI patients were older than STEMI patients, with more cardiovascular and noncardiovascular risk factors. In STEMI patients, the cumulative incidence of cardiovascular death was higher for ∼4 years following the index event, after which noncardiovascular death predominated. In UA/NSTEMI patients, the cumulative incidence of cardiovascular death remained higher than noncardiovascular death over the full follow‐up period. Patients ≥65 years old and <65 years old had a higher incidence of cardiovascular death than noncardiovascular death over the entirety of follow‐up. Female patients had a higher incidence of cardiovascular death than noncardiovascular death for ∼6 years following the index event; male patients had a higher incidence of cardiovascular death than noncardiovascular death over the entirety of follow‐up. Conclusions Among post‐ACS patients enrolled in a long‐term clinical trial, the relative incidence of cardiovascular and noncardiovascular death differed based on type of ACS presentation and sex, but not age. These findings further delineate long‐term prognosis after ACS and should inform the design of future cardiovascular outcomes trials.

Abstract
There is controversy regarding in-hospital mortality, revascularization, and other adverse outcomes in patients with ST-segment elevation (STEMI) and chronic obstructive pulmonary disease (COPD). We queried the 2003 to 2011 Nationwide Inpatient Sample databases to identify patients aged ≥18 years with a primary diagnosis of STEMI. Univariate and multivariate analyses were performed to evaluate the association of COPD with in-hospital clinical outcomes. Patients with COPD comprised 13.2% of 2,120,005 patients with STEMI. COPD was associated with older age, Medicare insurance, greater co-morbidities, and lower socioeconomic status. Compared with non-COPD patients, patients with COPD had higher inpatient mortality even after adjustment for multiple potential other factors (12.5% vs 8.6%, adjusted odds ratio [AOR] 1.13, 95% CI 1.11 to 1.15, p <0.001). Patients with COPD were more likely to develop new-onset heart failure (AOR 2.01, 95% CI 1.99 to 2.03), cardiogenic shock (AOR 1.24, 95% CI 1.22 to 1.26), and acute respiratory failure (AOR 2.46, 95% CI 2.43 to 2.50) during their hospital stay. Patients with COPD were less likely to undergo diagnostic angiographies and any revascularization procedures. The mean length of stay (6.0 vs 4.6 days; p <0.001) was greater in patients with COPD, as were hospital average hospital charges ($63,956 vs $58,536; p <0.001). In conclusion, among patients with STEMI, COPD is associated with a greater risk of in-hospital mortality, new-onset heart failure, acute respiratory failure, and cardiogenic shock.

Impact of chronic obstructive pulmonary disease on in-hospital morbidity and mortality in patients with ST-segment elevation myocardial infarction treated by primary percutaneous coronary intervention. Int J Cardiol 2017; 243:437-442. [PMID: 28506549 DOI: 10.1016/j.ijcard.2017.05.044] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2017] [Revised: 05/07/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) presenting with ST-segment elevation myocardial infarction (STEMI) are less likely to beneficiate of primary percutaneous coronary intervention (pPCI), and have poorer prognosis. We aimed to evaluate the impact of COPD on the in-hospital outcomes of pPCI-treated STEMI patients. METHODS Data were collected from 418 STEMI patients treated by pPCI. Inotropics and diuretics usage, cardiogenic shock, asystole, kidney dysfunction, and left ventricular ejection fraction were used as markers of hemodynamic complications. Atrial and ventricular fibrillation, conduction disorders, and antiarrhythmics usage were used as markers of arrhythmic complications. In-hospital mortality was evaluated. The associations between these parameters and COPD were assessed. RESULTS COPD was present in 7.42% of STEMI patients. COPD patients were older (p=0.02) and less likely to receive beta-blockers (OR 0.29; 95%CI 0.13-0.64; p<0.01). They had higher Killip class on admission (p<0.001), received more often inotropics (p<0.001) and diuretics (p<0.01), and presented more often atrial (p=0.01) and ventricular fibrillation (p=0.02). Unadjusted in-hospital mortality was higher in COPD patients (OR 4.18, 95%CI 1.55-11.30, p<0.01). After adjustment for potentially confounding factors except beta-blockers, COPD remained an independent predictor of in-hospital mortality (p=0.02). After further adjustment with beta-blocker therapy, no excess mortality was noted in COPD patients. CONCLUSIONS Despite being treated by pPCI, COPD patients with STEMI are more likely to develop hemodynamic and arrhythmic complications, and have higher in-hospital mortality. This appears to be due to lower beta-blockers usage in COPD patients. Increasing beta-blockers usage in COPD patients with STEMI may improve survival.

Chronic obstructive pulmonary disease and acute myocardial infarction: effects on presentation, management, and outcomes. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2016; 2:81-90. [PMID: 29474627 PMCID: PMC5862020 DOI: 10.1093/ehjqcco/qcw005] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2015] [Indexed: 01/09/2023]
Abstract
Cardiovascular disease is a common cause of death in patients with chronic obstructive pulmonary disease (COPD) and is a key target for improving outcomes. However, there are concerns that patients with COPD may not have enjoyed the same mortality reductions from acute myocardial infarction (AMI) in recent decades as the general population. This has raised questions about differences in presentation, management and outcomes in COPD patients compared to non-COPD patients. The evidence points to an increased risk of death after AMI in patients with COPD, but it is unclear to what extent this is attributable to COPD itself or to modifiable factors including under-treatment with guideline-recommended interventions and drugs. We review the evidence for differences between COPD and non-COPD patients in terms of the presentation of AMI, its treatment, and outcomes both in hospital and in the longer term.

Low forced expiratory volume in one second is associated with the history of acute coronary syndrome in patients with organic coronary stenosis. J Cardiol 2016; 69:131-135. [PMID: 26946928 DOI: 10.1016/j.jjcc.2016.01.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2015] [Revised: 01/20/2016] [Accepted: 01/29/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND Chronic obstructive pulmonary disease often coexists with cardiovascular diseases and airflow limitation has been known as a risk of cardiovascular death. However, the association between airflow limitation and the history of acute coronary syndrome (ACS) in patients with coronary stenosis remains to be determined. METHODS Study subjects were 271 consecutive patients (age: 70.6±9.5 years, sex: 200 males) who underwent coronary angiography and in whom organic coronary stenosis was detected. We collected spirometric data from those patients and investigated the association of the pulmonary function and the history of ACS. We also compared the prevalence of airflow limitation of the present subjects with Japanese epidemiological data that had been previously published. RESULTS Multivariate analysis with multiple logistic regression analysis showed that the reduced forced expiratory volume in one second (FEV1.0) less than 80% of predicted value was significantly associated with a history of ACS (odds ratio: 2.81, 95% CI: 1.27-6.20, p<0.02) independently of age, sex, body mass index, and classic coronary risk factors including smoking habit, diabetes mellitus, hypertension, and dyslipidemia. Furthermore, the airflow limitation was more prevalent in the present subjects than in the Japanese general population (25.8% vs. 10.9%, p<0.05). CONCLUSIONS Reduced FEV1.0 is associated with a history of ACS in patients with coronary arterial stenosis irrespective of any coronary risk factors. Airflow limitation is more prevalent in patients with coronary stenosis than in the general population.

Abstract
OBJECTIVES Cardiovascular disease is an important comorbidity in patients with chronic obstructive pulmonary disease (COPD). We aimed to systematically review the evidence for: (1) risk of myocardial infarction (MI) in people with COPD; (2) risk of MI associated with acute exacerbation of COPD (AECOPD); (3) risk of death after MI in people with COPD. DESIGN Systematic review and meta-analysis. METHODS MEDLINE, EMBASE and SCI were searched up to January 2015. Two reviewers screened abstracts and full text records, extracted data and assessed studies for risk of bias. We used the generic inverse variance method to pool effect estimates, where possible. Evidence was synthesised in a narrative review where meta-analysis was not possible. RESULTS Searches yielded 8362 records, and 24 observational studies were included. Meta-analysis showed increased risk of MI associated with COPD (HR 1.72, 95% CI 1.22 to 2.42) for cohort analyses, but not in case-control studies: OR 1.18 (0.80 to 1.76). Both included studies that investigated the risk of MI associated with AECOPD found an increased risk of MI after AECOPD (incidence rate ratios, IRR 2.27, 1.10 to 4.70, and IRR 13.04, 1.71 to 99.7). Meta-analysis showed weak evidence for increased risk of death for patients with COPD in hospital after MI (OR 1.13, 0.97 to 1.31). However, meta-analysis showed an increased risk of death after MI for patients with COPD during follow-up (HR 1.26, 1.13 to 1.40). CONCLUSIONS There is good evidence that COPD is associated with increased risk of MI; however, it is unclear to what extent this association is due to smoking status. There is some evidence that the risk of MI is higher during AECOPD than stable periods. There is poor evidence that COPD is associated with increased in hospital mortality after an MI, and good evidence that longer term mortality is higher for patients with COPD after an MI.

Closing the mortality gap after a myocardial infarction in people with and without chronic obstructive pulmonary disease. Heart 2015; 101:1103-10. [PMID: 25765553 PMCID: PMC4516011 DOI: 10.1136/heartjnl-2014-307251] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2014] [Accepted: 02/13/2015] [Indexed: 11/06/2022] Open
Abstract
Objective Patients with chronic obstructive pulmonary disease (COPD) have increased mortality following myocardial infarction (MI) compared with patients without COPD. We investigated the extent to which differences in recognition and management after MI could explain the mortality difference. Methods 300 161 patients with a first MI between 2003 and 2013 were identified in the UK Myocardial Ischaemia National Audit Project database. Logistic regression was used to compare mortality in hospital and at 180 days postdischarge between patients with and without COPD. Variables relating to inhospital factors (delay in diagnosis, use of reperfusion and time to reperfusion/use of angiography) and use of secondary prevention were sequentially added to models. Results Mortality was higher for patients with COPD both inhospital (4.6% vs 3.2%) and at 180 days (12.8% vs 7.7%). After adjusting for inhospital factors, the effect of COPD on inhospital mortality after MI was reduced for both ST-elevation myocardial infarctions (STEMIs) and non-STEMIs (STEMIs OR 1.24 (95% CI 1.10 to 1.41) to 1.13 (95% CI 0.99 to 1.29); non-STEMIs OR 1.34 (95% CI 1.24 to 1.45) to 1.16 (95% CI 1.07 to 1.26)). Adjusting for inhospital factors reduced the effect of COPD on mortality after non-STEMI at 180 days (OR 1.56 (95% CI 1.47 to 1.65) to 1.37 (95% CI 1.31 to 1.44)). Adjusting for use of secondary prevention also reduced the effect of COPD on mortality at 180 days for STEMIs and non-STEMIs (STEMIs OR 1.45 (95% CI 1.31 to 1.61) to 1.25 (95% CI 1.11 to 1.41); non-STEMIs OR 1.37 (95% CI 1.31 to 1.44) to 1.26 (95% CI 1.17 to 1.35). Conclusions Delayed diagnosis, timing and use of reperfusion of a STEMI, use of angiography after a non-STEMI and use of secondary prevention medicines are all potential explanations for the mortality gap after MI in people with COPD.
