Abstract
There are few theories and little empirical evidence about the bilateral impact of substance use and coronavirus disease 2019 (COVID-19), so a logical and accurate picture of this area is required. We investigated the effects of opium use on severity of disease on hospitalized COVID-19 patients in east of Iran. Demographic and clinical characteristics, vital signs, laboratory tests, mortality rate, type and duration of opium consumption in hospitalized patients who recovered from COVID-19 in the follow-up after 3 months were evaluated. In this study, 60 (20%) participants were the opium user and 251 (80%) were the non-user patients. Based on clinical symptoms, hypertension and systolic blood pressure in opium user were significantly higher than non-user patients (p < 0.05). In the laboratory tests, only the level of urea was higher in the opium positive group (37 [26.5-48.5] vs. 32 [23-43], respectively) and the percent of lymphocytes were lower in the opium positive (17 [8.2-25.8] vs. 18.7 [13.85-26.35], respectively). The initial therapies of both opium positive and negative infected patients showed not any significant changes (p > 0.05). Among the studied groups, one deceased case with COVID-19 was related to a drug user patient. Although, uses of opium reduced the levels of some risk factors, vital signs at admission and initial therapies during hospitalization in COVID-19 patients but it increased lung and heart diseases. Also, the severity of COVID-19 including hospitalization and mortality were associated with opium consumption.

Global Insights into Chronic Obstructive Pulmonary Disease and Coronary Artery Disease: A Systematic Review and Meta-Analysis of 6,400,000 Patients. Rev Cardiovasc Med 2024; 25:25. [PMID: 39077650 PMCID: PMC11262403 DOI: 10.31083/j.rcm2501025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 08/13/2023] [Accepted: 08/24/2023] [Indexed: 07/31/2024] Open
Abstract
Background The high prevalence of chronic obstructive pulmonary disease (COPD) in coronary artery disease (CAD) has been acknowledged over the past decade, although the cause/s remain uncertain due to differences in diagnoses. COPD has also become a leading CAD comorbidity, although again little is known about its interactions. This meta-analysis explored COPD prevalence in the global CAD population, as well as the influence of COPD on CAD. Methods PubMed, Web of Science, Embase, and grey literature were searched until 26th November 2021. The prevalence of COPD was calculated, and data were grouped according to COPD diagnostic methods, interventions, region, economic status, etc. Outcomes including all-cause death, cardiac death, myocardial infarction, revascularization, stroke, heart failure, and respiratory failure were analyzed. This study was registered with PROSPERO (CRD No.42021293270). Results There was an average prevalence of 14.2% for COPD in CAD patients (95% CI: 13.3-15.1), with diagnostics of COPD through spirometry, International Classification of the Diseases (ICD codes), and self-reported methods. Comorbid COPD-CAD patients were more likely to be smokers and suffer from cardiovascular and respiratory complications (all odds ratios [OR] > 1). COPD-CAD has higher mortality (hazard ratio [HR] 2.81, 95% CI: 2.40-3.29), and myocardial infarction, stroke, and respiratory failure rates (all HR > 1). Coronary artery bypass graft (CABG) reduces the need for revascularization (HR 0.43, 95% CI: 0.20-0.94) compared to percutaneous coronary intervention (PCI), without increasing mortality. Conclusions The global prevalence of COPD is particularly high in CAD patients. COPD-CAD patients are more likely to encounter cardiovascular and respiratory complications and endure poorer outcomes. Limited evidence suggests that CABG may reduce the need for revascularization without increasing mortality, although further research is required to confirm these observations.

Abstract
We performed a meta-analysis to evaluate the effect of chronic obstructive pulmonary disease on surgical site wound infection, and other postoperative problems after coronary artery bypass grafting. A systematic literature search up to April 2022 was performed and 37 444 subjects with coronary artery bypass grafting at the baseline of the studies; 4320 of them were with the chronic obstructive pulmonary disease, and 33 124 were without chronic obstructive pulmonary disease. Odds ratio (OR), and mean difference (MD) with 95% confidence intervals (CIs) were calculated to assess the effect of chronic obstructive pulmonary disease on surgical site wound infection, and other postoperative problems after coronary artery bypass grafting using the dichotomous, and contentious methods with a random or fixed-effect model. The chronic obstructive pulmonary disease subjects had a significantly higher surgical site wound infection (OR, 1.27; 95% CI, 1.01-1.60, P = 0.04), respiratory failure (OR, 1.84; 95% CI, 1.55-2.18, P < 0.001), mortality (OR, 1.61; 95% CI, 1.37-1.89, P < 0.001), pneumonia (OR, 2.30; 95% CI, 1.97-2.68, P < 0.001), pleural effusion (OR, 1.78; 95% CI, 1.12-2.83, P = 0.02), stroke (OR, 1.99; 95% CI, 1.17-3.36, P = 0.01), and length of intensive care unit stay (MD, 0.73; 95% CI, 0.19-1.26, P = 0.008) after coronary artery bypass grafting compared with subjects without chronic obstructive pulmonary disease. However, chronic obstructive pulmonary disease subjects did not show any significant difference in length of hospital stay (MD, 0.83; 95% CI, -0.01 to 1.67, P = 0.05), and pneumothorax (OR, 1.59; 95% CI, 0.98-2.59, P = 0.06) after coronary artery bypass grafting compared with subjects without chronic obstructive pulmonary disease. The chronic obstructive pulmonary disease subjects had a significantly higher surgical site wound infection, respiratory failure, mortality, pneumonia, pleural effusion, stroke, and length of intensive care unit stay, and no significant difference in length of hospital stay, and pneumothorax after coronary artery bypass grafting compared with subjects without chronic obstructive pulmonary disease. The analysis of outcomes should be with caution because of the low sample size of 1 out of 11 studies in the meta-analysis and a low number of studies in certain comparisons.

Abstract
INTRODUCTION Coronary artery bypass grafting (CABG) is a crucial intervention in acute myocardial infarction (AMI), particularly when AMI is not amenable for management with primary percutaneous coronary intervention (PCI). To optimise outcome in these patients, surgical teams must consider a host of predictive factors, with the most prominent being the timing of CABG. Despite numerous studies exploring timing of CABG following AMI in the past, optimal surgical timing remains controversial. The mortality rates vary with timing of CABG, but confounding factors such as age, impaired pulmonary function, renal insufficiency, and poor left ventricular function may contribute to varied outcomes reported. EVIDENCE ACQUISITON An electronic literature search of articles that discussed acute myocardial presentation and urgent in-patient or elective CABG was conducted. EVIDENCE SYNTHESIS The evidence was synthesised based on each reported article and their outcomes. CONCLUSIONS Current literature suggests multiple factors can guide CABG timing including, type of AMI at initial presentation, distinctive pathological status and patient characteristics. Thus, there is a need for large, multi-centre studies to identify optimal CABG timing in complex coronary artery disease or failed PCI in patients with AMI. Future guidelines should emphasise patient cohorts by taking their risk factors into consideration. As such, a need for greater cardiac screening methods and development of scoring systems can aid in the optimisation of CABG timing.

Abstract
OBJECTIVES This study sought to compare clinical outcomes between three categories of patients: non-chronic obstructive pulmonary disease (COPD), diagnosed COPD and undiagnosed COPD in coronary artery bypass grafting surgery. METHODS A single-centred retrospective study from January 2010 to December 2019. Primary outcomes were postoperative complications, length of ITU admission and in-hospital staying. Secondary outcomes were reintervention rate, in-hospital and long-term mortality. RESULTS A total of 4020 patients were analysed and divided into three cohorts: non-COPD (group A) (74.55%, n=2997), diagnosed COPD (group B) (14.78%, n=594) and undiagnosed COPD (group C) (10.67%, n=429). The rate of respiratory complications was noted in this order: group B>group C>group A (p 0.00000002). Periooperative acute kidney injury and wound complications were higher in group B (p 0.0004 and p 0.03, respectively). Prolonged in-hospital staying (days) resulted in group B (p 0.0009). Finally, long-term mortality was statistically higher in group B and C compared with group A (p 0.0004). No difference in long-term mortality was noted in relation to the expected FEV1% in group B (p 0.29) and group C (p 0.82). CONCLUSIONS In CABG surgery, COPD is a well-known independent risk factor for morbidity. Patients with preoperative spirometry results indicative of COPD result in the same outcomes of known patients with COPD. As a result of that, greater value should be given to the preoperative spirometry in the EuroSCORE. Finally, the expected FEV1% appears not be a predictor for long-term survival.

Abstract
STUDY DESIGN This was a retrospective cohort study. OBJECTIVE The objective of this study was to analyze readmission rates among patients undergoing anterior cervical discectomy and fusion (ACDF), determine which factors were associated with higher readmission rates, and develop a scale for utilization during surgical planning. SUMMARY OF BACKGROUND DATA ACDF is the most common surgical treatment for many cervical disk pathologies. With the Centers for Medicare and Medicaid Services selecting readmissions as a measure of health care quality, there has been an increased focus on reducing readmissions. MATERIALS AND METHODS There were 114,174 recorded ACDF surgeries in the derivation cohort, the State Inpatient Database (SID) of New York and California between 2006 and 2014. There were 115,829 ACDF surgeries recorded in the validation cohort, the SID from Florida and Washington over the same time period. After identification of risk factors using univariate and multivariate analysis of the derivation cohort, a predictive scale was generated and tested utilizing the validation cohort. RESULTS Overall, readmission rates within 30 days of discharge were 5.87% and 5.52% in the derivation and validation cohorts, respectively. On multivariate analysis of the derivation cohort, age older than 80 years [odds ratio (OR), 1.67] male sex (OR, 1.16), Medicaid insurance (OR, 1.90), Medicare insurance (OR, 1.64), revision ACDF (OR, 1.43), anemia (OR, 1.45), chronic lung disease (OR, 1.23), coagulopathy (OR, 1.42), congestive heart failure (OR, 1.31), diabetes (OR, 1.23), fluid and electrolyte disorder (OR, 1.56), liver disease (OR, 1.37), renal failure (OR, 1.59), and myelopathy (OR, 1.19) were found to be statistically significant predictors for readmission. These factors were incorporated into a numeric scale that, that when tested on the validation cohort, could explain 97.1% of the variability in readmission rate. CONCLUSIONS Overall, 30-day readmission following ACDF surgery was 5%-6%. A novel risk scale based on factors associated with increased readmission rates may be helpful in identifying patients who require additional optimization to reduce perioperative morbidity. LEVEL OF EVIDENCE Level III-prognostic.

Abstract
Objective To observe spirometry and its correlation with postoperative pulmonary complications in cardiac surgery patients. Study design Prospective observational study Place and duration of the study Chaudhary Pervaiz Elahi Institute of Cardiology (CPEIC) Multan, from January 1, 2017, to June 30, 2020 Methodology Written informed consent was taken from 357 patients. Spirometry was performed in all the patients using the conventional method. Baseline data, including gender, age, body mass index (BMI), living area, smoking history, known lung illness, six-minute walk distance, predicted forced vital capacity (FVC) %, predicted forced expiratory volume in one second (FEV1) %, and type of the procedure such as aortic valve replacement (AVR), coronary artery bypass grafting (CABG), double-valve replacement (DVR), and mitral valve replacement (MVR) were documented for all the patients. Outcome data included postoperative ICU length of stay (LOS), respiratory failure, respiratory infection, atelectasis, and mortality. Results The most common procedure was CABG and MVR proceeded by n=254 (71.1%) and n=83 (23.2%) patients, respectively. Postoperative complications, such as respiratory failure, respiratory infection, and atelectasis, was noted in n=29 (8.1%), n=28 (7.8 %), and n=127 (35.6 %) patients, respectively, while n=5 (1.4%) patients died. Conclusion Deranged pulmonary function tests (PFTs) are associated with poor prognosis following elective cardiac surgery in terms of postoperative pulmonary complications such as pulmonary infection, respiratory failure, and atelectasis. There is a significant difference in percentage predicted of FVC and FEV1 in patients who developed atelectasis and respiratory tract infection.

Abstract
Backgrounds Cardiovascular disease (CVD) is the leading cause of mortality all over the globe. Inflammation is believed to play a pivotal role in the pathophysiology of CVD. While there are studies on the interrelationship of telomerase and vitamin D and their involvement in CVD, their independent contributions to long-term outcomes in patients with CVD are not well-defined. This study aimed to investigate the association of both telomerase and vitamin D concentrations with 10-year survival among candidates of coronary artery bypass grafting (CABG) surgery. Methods Participants were 404 patients from Tehran Heart Center-Coronary Outcome Measurement (THC-COM) cohort who were recruited from CABG surgery candidates in 2006. In addition to demographic and clinical data including risk factors for coronary artery disease, laboratory parameters such as markers of inflammation as well as baseline serum 25-hydroxy vitamin D [25(OH)D] and telomerase concentrations were measured. Cardiac function indexes alongside outcome measures such as mortality and survival days were recorded for every patient up to 10 years after CABG. Cox-proportional hazard model was used to study the association between all-cause mortality and research parameters. Results The mean serum telomerase enzyme level was 24.92 ±21.4 nmol/L and the mean serum 25(OH)D was 27.27±10.3 ng/mL. 10-year mortality was reported in 64 (15.8%) patients. 25(OH)D was categorized into three groups (<20, 20–30, and >30) and the cut-point for telomerase was set at 25.0 nmol/L. In Cox regression analysis, higher levels of telomerase (>25 nmol/L) were significantly associated with longer survival (p = 0.041), whereas 25(OH)D concentrations were not associated with survival time. Further analysis showed that telomerase concentrations significantly predicted survival only in the presence of insufficient levels of 25(OH)D (20–30 ng/mL) (p = 0.037). Conclusions Telomerase can be regarded as a potential predictor of long-term outcomes in patients who underwent CABG. However, the association of telomerase with the mortality may be modified by vitamin D concentrations.

Abstract
Elective cardiac surgery accounts for a significant proportion of perioperative resource allocation in Australasia. Preoperative pulmonary function testing (PFT) is routinely undertaken in some centres to identify patients who may require prolonged ventilation and intensive care unit (ICU) stay, although there are currently no data supporting this practice. Routine PFT places a burden on respiratory diagnostic laboratories, is inconvenient to patients and may delay surgery. We aimed to identify whether PFT parameters identify patients requiring prolonged mechanical ventilation after elective cardiac surgery. Adult patients admitted to the Royal Adelaide Hospital ICU following elective cardiac surgery between July 2013 and December 2017 were identified retrospectively from the local ICU database. Preoperative PFT and operative and postoperative outcome data were retrieved from local databases, and multivariable logistic regression was undertaken to identify which PFT variables were associated with prolonged mechanical ventilation. PFT data were available for 835/1139 (73%) elective cardiac surgical cases. The best independent predictors of prolonged mechanical ventilation were post-bronchodilator forced vital capacity (FVC) and single-breath diffusing capacity for carbon monoxide (DLCO). Patients with FVC <80% predicted and DLCO <60% predicted had an odds ratio for prolonged postoperative ventilation of 7.5 (95% confidence intervals 3.6–15.6; P < 0.001). The area under the receiver operating characteristic curve derived from this model was 0.68. Abnormal PFT results were associated with prolonged postoperative mechanical ventilation. A PFT-based prediction tool does not accurately predict individual patient outcome but identifies a cohort of patients at higher risk of requiring prolonged ventilation, potentially informing ICU resource allocation and surgical planning.

Abstract
Although a simple and useful pulmonary function test, spirometry remains underutilized in India. The Indian Chest Society and National College of Chest Physicians (India) jointly supported an expert group to provide recommendations for spirometry in India. Based on a scientific grading of available published evidence, as well as other international recommendations, we propose a consensus statement for planning, performing and interpreting spirometry in a systematic manner across all levels of healthcare in India. We stress the use of standard equipment, and the need for quality control, to optimize testing. Important technical requirements for patient selection, and proper conduct of the vital capacity maneuver, are outlined. A brief algorithm to interpret and report spirometric data using minimal and most important variables is presented. The use of statistically valid lower limits of normality during interpretation is emphasized, and a listing of Indian reference equations is provided for this purpose. Other important issues such as peak expiratory flow, bronchodilator reversibility testing, and technician training are also discussed. We hope that this document will improve use of spirometry in a standardized fashion across diverse settings in India.

Postoperative outcomes of patients with chronic obstructive pulmonary disease undergoing coronary artery bypass grafting surgery: A meta-analysis. Medicine (Baltimore) 2019; 98:e14388. [PMID: 30732179 PMCID: PMC6380818 DOI: 10.1097/md.0000000000014388] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Revised: 01/03/2019] [Accepted: 01/12/2019] [Indexed: 01/14/2023] Open
Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a frequent comorbid disease in patients undergoing coronary artery bypass grafting (CABG) surgery, with an incidence ranging from 4% to 20.5%. Conventionally, COPD was recognized as a surgical contraindication to CABG. Because of the recent improvements in surgical techniques, anesthesia, and postoperative management, CABG has been performed more commonly in patients with COPD. However, studies have shown the various effects of COPD on postoperative morbidity and mortality after CABG, and this remains to be well defined. OBJECTIVES To compare the postoperative outcomes after CABG between patients with and those without COPD. METHODS A systematic search was conducted in the Cochrane Library, PubMed, EmBase, and Ovid databases (until May 10, 2018). Studies comparing perioperative results and mortality outcomes after CABG between patients with and those without COPD were evaluated independently by 2 reviewers to identify the potentially eligible studies. Review Manager and STATA software were used for statistical analyses. RESULTS No significant difference in the mortality rates were found between patients with and those without COPD. COPD was associated with a higher respiratory failure rate (odds ratio [OR] = 4.01; 95% CI: 1.19-13.51, P = .03; P <.001 for heterogeneity), higher pneumonia rate (OR = 2.92; 95% CI: 2.37-3.60, P <.00001; P = .73 for heterogeneity), higher stroke rate (OR = 2.91; 95% CI: 1.37-6.18, P = .005; P = .60 for heterogeneity), higher renal failure rate (OR = 1.60; 95% CI: 1.30-1.97, P <.00001; P = .19 for heterogeneity), and higher wound infection rate (OR = 2.16; 95% CI: 1.21-3.88, P = .01; P = .53 for heterogeneity) after CABG. CONCLUSIONS Patients with COPD were at higher risks for developing postoperative morbidities, particularly pneumonia, respiratory failure, stroke, renal failure, and wound infection. Although COPD was not associated with a higher risk of mortality, caution should be taken when a patient with COPD is indicated for CABG, considering the higher odds of postoperative complications involving the respiratory system and others.

Najafi M, Jahangiry L, Mortazavi SH, Jalali A, Karimi A, Bozorgi A. Outcomes and long-term survival of coronary artery surgery: The controversial role of opium as risk marker. World J Cardiol 2016; 8:676-683. [PMID: 27957254 PMCID: PMC5124726 DOI: 10.4330/wjc.v8.i11.676] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Revised: 07/31/2016] [Accepted: 09/08/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To study survival in isolated coronary artery bypass graft (CABG) patients and to evaluate the impact of preoperative chronic opium consumption on long-term outcome.
METHODS Cohort of 566 isolated CABG patients as Tehran Heart Center cardiac output measurement was conducted. Daily evaluation until discharge as well as 4- and 12-mo and 6.5-year follow-up information for survival status were fulfilled for all patients. Long-term 6.5-year overall and opium-stratified survival, adjusted survival curves based on opium consumption as well as possible predictors of all-cause mortality using multiple cox regression were determined by statistical analysis.
RESULTS Six point five-year overall survival was 91.8%; 86.6% in opium consumers and 92.7% in non-opium consumers (P = 0.035). Patients with positive history of opium consumption significantly tended to have lower ejection fraction (EF), higher creatinine level and higher prevalence of myocardial infarction. Multiple predictors of all-cause mortality included age, body mass index, EF, diabetes mellitus and cerebrovascular accident. The hazard ratio (HR) of 2.09 for the risk of mortality in opium addicted patients with a borderline P value (P = 0.052) was calculated in this model. Further adjustment with stratification based on smoking and opium addiction reduced the HR to 1.20 (P = 0.355).
CONCLUSION Simultaneous impact of smoking as a confounding variable in most of the patients prevents from definitive judgment on the role of opium as an independent contributing factor in worse long-term survival of CABG patients in addition to advanced age, low EF, diabetes mellitus and cerebrovascular accident. Meanwhile, our findings do not confirm any cardio protective role for opium to improve outcome in coronary patients with the history of smoking. Further studies are needed to clarify pure effect of opium and warrant the aforementioned findings.
