Abstract
PURPOSE Patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) are a high-risk subset of patients, whose optimal antithrombotic treatment strategy, involving a combination of anticoagulant and antiplatelet agents, has not been well defined. Our study aims to investigate contemporary "real-world" trends of antithrombotic treatment strategies in AF patients undergoing PCI, as well as identify factors affecting decision-making at hospital discharge. METHODS "Real-world" data were retrieved from the GReek-AntiPlatElet Atrial Fibrillation (GRAPE-AF) registry, a contemporary, nationwide, multicenter, observational study of AF patients undergoing PCI. Characteristics of patients discharged on triple antithrombotic therapy (TAT) or dual antithrombotic therapy (DAT) were compared in order to identify factors that could influence treatment decisions. RESULTS A total of 654 patients were enrolled (42% with stable coronary artery disease, 58% with acute coronary syndrome). TAT was adopted in 49.9% and DAT in 49.2% of patients at discharge. Regarding anticoagulants, the vast majority of patients (92.9%) received non-vitamin K antagonist oral anticoagulants (NOACs) and only 7.1% received vitamin K antagonists (VKAs). Dyslipidemia, insulin-dependent diabetes mellitus, prior myocardial infarction, acute coronary syndrome at presentation, and regional variations were predictive of TAT adoption, whereas the use of NOACs or ticagrelor was predictive of DAT adoption. CONCLUSION Contemporary "real-world" data concerning antithrombotic treatment in AF patients undergoing PCI indicate a strong shift towards the use of NOACs instead of VKAs, along with a large subset of patients adopting an aspirin-free strategy early after index PCI, with clinical as well as treatment characteristics affecting decision-making.

Abstract
PURPOSE Malnutrition has been shown to be related to adverse clinical outcomes in patients with heart failure, hypertension, atrial fibrillation and other cardiovascular diseases. However, in the patients with coronary artery disease (CAD) undergoing percutaneous coronary interventions (PCI), especially in the elderly, the association of nutritional state and all-cause mortality remains unknown. We aimed to investigate the association of malnutrition with all-cause mortality in the elder patients undergoing PCI. PATIENTS AND METHODS Based on the largest retrospective and observational cohort study from January 2007 to December 2017, the Controlling Nutritional Status (CONUT) score was applied to 21,479 consecutive patients with age ≥60 who undergoing PCI for nutritional assessment. Participants were classified as absent, mild, moderate and severe malnutrition by CONUT score. The Kaplan-Meier method was used to compare all-cause mortality among the above four groups. Multivariable Cox proportional hazard regression analyses were performed to examine the association of malnutrition with all-cause mortality. RESULTS According to the CONUT score, 48.19%, 15.08% and 0.94% patients were mildly, moderately and severely malnourished, respectively. During a median follow-up of 5.16 years (interquartile range: 3.02 to 7.89 years), 3173 (14.77%) patients died. Kaplan-Meier analysis showed that the risk of all-cause mortality was significantly higher in patients with a worse nutritional status. Compared with normal nutritional state, malnutrition was associated with significantly increased risk for all-cause mortality (adjusted hazard ratio for mild, moderate and severe degrees of malnutrition, respectively: 1.20 [95% confidence interval (CI): 1.09 to 1.33], 1.32 [95% CI: 1.17 to 1.49] and 1.76 [95% CI: 1.33 to 2.33]). CONCLUSION Malnutrition is prevalent among elderly patients with CAD undergoing PCI, and is strongly related to the all-cause mortality increasing. For elderly patients with CAD undergoing PCI, it is necessary to assess the status of nutrition, and evaluate the efficacy of nutritional interventions.

Abstract
BACKGROUND There are few reports on the significance for the combined evaluation of blood humoral factors and urinary biomarkers in terms of worsening renal function (WRF) after coronary angiography (CAG)/percutaneous coronary arterial intervention (PCI). METHOD AND RESULTS Urinary liver type-fatty acid-binding protein (L-FABP), neutrophil gelatinase associated lipocalin (NGAL), and adrenomedullin (AM) were measured less than 24 h before and 3 h, 6 h, 1 day, and 2 days after CAG/PCI. WRF was defined as a > 20% decrease in the estimated GFR. WRF occurred in seven of 100 patients and the increase in L-FABP/creatinine (Cr) at 1 day after CAG/PCI was significantly higher in the WRF group than in the non-WRF group. Plasma B-type natriuretic peptide (BNP) before CAG/PCI and L-FABP/Cr at 1 day after CAG/PCI were independent predictors for WRF. The areas under the receiver-operating characteristic curves were as follows: 0.760 for BNP before CAG/PCI, 0.731 for L-FABP/Cr at 1 day after CAG/PCI, and 0.892 for BNP and L-FABP/Cr. Urinary AM levels after PCI/CAG were negatively correlated only to serum potassium levels. Gene expressions of AM and AM-receptor were detectable in renal tubule epithelial cells. AM increased intracellular second messenger levels in a dose-dependent manner. CONCLUSIONS Our results suggest that combined evaluation of plasma BNP and urinary L-FABP/Cr is useful as a predictor of renal dysfunction in CAG/PCI patients.

Journal of Ayub Medical College, Abbottabad : JAMC. 2021;(1):26-29
Abstract
BACKGROUND Acute coronary syndrome (ACS) is one of the leading causes of death worldwide. It is characterized by the formation of coronary artery thrombus which can be either due to plaque rupture, plaque erosion or rupture of a calcific nodule. The aim of study was to assess the plaque morphology leading acute coronary syndrome using OCT and to guide management based on its findings. It was an observational study, conducted at Rawalpindi Institute of Cardiology from Jan to Dec 2019. METHODS Fifty patients meeting the inclusion criteria were included in the study. OCT procedure was performed following intracoronary injection of 100-150 ug of nitroglycerine. The imaging catheter (OFDI dragon view) of the OCT device (Terumo Luna wave OFDI, Tokyo, Japan) was inserted into the culprit artery. Blood clearance was achieved by injecting diluted iodinated contrast at the rate of 5 ml/sec. Imaging acquisition was obtained following automated pullback at the rate of 25 mm/sec. Pathologies like stent under deployment, mal-apposition, strut fracture, plaque erosion, plaque rupture were assessed by the operating interventionist well versed with the OCT technology and lesion assessment. Data analysis was done using the SPSS version 26. Categorical variables were presented as counts and percentages while continuous variables as mean±SD. RESULTS A total of 50 patients were included in the study. The mean age was 49.24±11.92. Majority of the patients were male comprising 78.0% of the cases. Plaque rupture was the most common underlying pathology seen in 32.5% of the patients and exclusively in STEMI patients which required stent deployment. Thin cap fibroatheroma was seen in 27.9% of the cases while lipid rich plaque in 23.2% of the cases; again, requiring stent deployment. 9.3% of the cases had plaque erosion while 4.6% had calcific nodule and only 2.3% had intramural hematoma which were treated conservatively. 42.8% of the stent thrombosis patients had under-deployed stents requiring balloon dilatation while 14.2% had mal-apposed stent again requiring balloon dilatation. In contrast 14.2% each had neo-atherosclerosis, stent strut fracture and uncovered stent struts as the underlying pathology for stent thrombosis each requiring stent deployment. CONCLUSIONS OCT guided PCI in cases of acute coronary syndrome is a valuable modality that gives insight into the underlying pathology of the disease process and also guides in proper management.

Abstract
BACKGROUND A strong association between on-thienopyridine platelet reactivity (PR) and the risk of both thrombotic and bleeding events in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) has been demonstrated. However, no study has analyzed the relationship between on-ticagrelor PR and clinical outcome in this clinical setting. OBJECTIVES We aimed to investigate the relationship between on-ticagrelor PR, assessed by the vasodilator-stimulated phosphoprotein (VASP) index, and clinical outcome in patients with ACS undergoing PCI. METHODS We performed a prospective, multicenter, observational study of patients undergoing PCI for ACS. PR was measured using the VASP index following ticagrelor loading dose. The primary study endpoint was the rate of Bleeding Academic Research Consortium (BARC) type ≥2 at 1 year. The key secondary endpoint was the rate of major adverse cardiovascular events (MACE) defined as the composite of cardiovascular death, myocardial infarction, stroke, and urgent revascularization. RESULTS We included 570 ACS patients, among whom 33.9% had ST-elevation myocardial infarction. BARC type ≥2 bleeding occurred in 10.9% and MACE in 13.8%. PR was not associated with BARC ≥2 or with MACE (p = 0.12 and p = 0.56, respectively). No relationship between PR and outcomes was observed, neither when PR was analyzed quantitatively nor when it was analyzed qualitatively (low on-treatment PR [LTPR] vs. no LTPR). CONCLUSION On-ticagrelor PR measured by the VASP was not associated with bleeding or thrombotic events in ACS patients undergoing PCI. PR measured by the VASP should not be used as a surrogate endpoint in studies on ticagrelor.

Abstract
BACKGROUND The aim of this study is to compare the long-term prognosis of non-ST elevation acute coronary syndrome (NSTE-ACS) patients with 3-vessel disease (3VD) who underwent percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) or medical therapy (MT).Methods and Results:Overall, 3,928 NSTE-ACS patients with 3VD were consecutively enrolled from April 2004 to February 2011 at Fu Wai Hospital. Patients were followed up for a median of 7.5 years, and were divided into PCI, CABG or MT groups according to their treatment. Compared with patients undergoing PCI, CABG patients had lower rates of myocardial infarction (MI), unplanned revascularization, major adverse cardiovascular and cerebrovascular events (MACCE) and a higher rate of stroke (all P<0.05). Compared with MT, PCI and CABG had lower incidences of all adverse outcomes (all P<0.05), except for a similar rate of stroke between PCI and MT. Kaplan-Meier analysis showed similar results. After adjusting for confounders, CABG was independently associated with a lower risk of cardiac death, revascularization and MACCE compared with PCI (all P<0.05). Compared with MT, PCI reduced long-term risk of death, whereas CABG reduced long-term risk of death, revascularization and MACCE events (all P<0.05). CONCLUSIONS In NSTE-ACS patients with 3VD, CABG is independently associated with a lower risk of long-term cardiac death, revascularization and MACCE compared with PCI. Patients who received MT alone had the highest risk of long-term MACCE.

Abstract
Myocardial injury is a problem associated with percutaneous coronary intervention (PCI). This study aimed to clarify the role of nicorandil administration in preventing myocardial injury. This study included patients with stable angina who underwent PCI from November 2013 to June 2016. Of 58 consecutive patients, the first 20 patients received only saline infusion after PCI (control group); the other 38 patients received a continuous intravenous infusion of nicorandil and saline after PCI (nicorandil group). Troponin I and brain natriuretic peptide (BNP) levels were measured. Vascular parameters, such as blood pressure (BP), cardiac output, cardio-ankle vascular index (CAVI), and estimated systemic vascular resistance (eSVR), were measured. Troponin I of both groups increased 12 h after PCI. Changes in BNP levels between immediately after PCI and 12 h after PCI were significantly higher in the control than in the nicorandil group (10.8 ± 44.2 vs. - 2.6 ± 14.6 pg/ml, p = 0.04). In the nicorandil group, BP, eSVR, and CAVI decreased significantly at 12 h after PCI compared with those immediately after PCI (p < 0.0001), whereas no change was observed in the control group. In a single linear analysis, the change in BP (r = 0.36, p < 0.01) and nicorandil administration (r = - 0.47, p < 0.001) was significantly correlated with the change in CAVI, multiple regression analysis revealed that the changes in CO and eSVR were significant contributing factors for the changes in CAVI. PCI could result in myocardial injury and/or cardiac burden in patients with stable angina. Nicorandil administration after PCI may be effective in relieving the burden by decreasing arterial stiffness (CAVI).

Abstract
OBJECTIVE This study assessed whether high levels of iodide administered during percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) differentially influenced thyroid function compared to PCI for non-complex coronary lesions. SUBJECTS AND METHODS A total of 615 patients were enrolled in the study; 205 underwent elective PCI for CTO lesions (Group I) and 410 underwent elective PCI for non-complex lesions including non-CTO, non-bifurcation, non-calcified, and non-tortuous lesions (Group II). Patients were monitored for development of incidental thyroid dysfunction between 1 and 6 months after PCI. RESULTS The patients in Group I were administered a median of 255 mL of contrast medium during PCI for CTO; a median of 80 mL was administered to the patients in Group II during non-complex PCI (p =0.001). Ten (5.4%) of the 186 euthyroid patients in Group I and 19 (5%) of the 379 eu-thyroid patients in Group II developed subclinical hyper-thyroidism (p = 0.854). However, 7 (50%) of the 14 subclinical hyperthyroid patients in Group I and only 3 (12%) of the 25 subclinical hyperthyroid patients in Group II developed overt hyperthyroidism (p = 0.019). CONCLUSION In euthyroid patients, PCI for coronary CTO lesions did not increase the risk for subclinical hyperthyroidism when compared to PCI for non-complex coronary lesions. However, in patients with subclinical hyperthyroidism at baseline, PCI for coronary CTO lesions significantly increased the development of overt hyperthyroidism when compared to PCI for non-complex coronary lesions.

Cardiovascular diabetology. 2020;(1):116
Abstract
BACKGROUND Previous studies have investigated the relationship of the triglyceride glucose (TyG) index with the incidence of cardiovascular events. However, to date, there have been no studies comparing the predictive values of fasting plasma glucose (FPG), glycosylated hemoglobin A (HbA1C) and the TyG index for the risk of cardiovascular events. This study aimed to use discordance analysis to evaluate and compare the effectiveness of FPG, HbA1C and the TyG index to predict the risk of cardiovascular events. METHODS Patients diagnosed with acute coronary disease (ACS) undergoing percutaneous coronary intervention (PCI) were enrolled in this study. The TyG index was computed using the following formula: ln [fasting triglycerides (mg/dL) × FPG (mg/dL)/2]. We categorized patients into 4 concordance/discordance groups. Discordance was defined as a TyG index equal to or greater than the median and an FPG or HbA1C less than the median, or vice versa. The primary outcome was the composite of death, nonfatal myocardial infarction, nonfatal stroke and unplanned repeat revascularization. A Cox proportional hazards regression model was performed to estimate the risk of cardiovascular events according to the concordance/discordance groups. Sensitivity analysis was performed on each patient group divided into high or low categories for HbA1C or FPG and were repeated according to diabetes status. RESULTS In total, 9285 patients were included in the final statistical analysis (male: 75.3%, age: 59.9 ± 10.05 years, BMI: 26.2 ± 9.21 kg/m2, diabetes: 43.9% and dyslipidemia: 76.8%). The medians defining concordance/discordance were 6.19 mmol/L for FPG, 6.1% for HbA1C and 8.92 for the TyG index. The TyG index was strongly related to triglycerides and HDL-C (r = 0.881 and -0.323, respectively; both P < 0.001). During the 17.4 ± 2.69 months of follow-up, there were 480 (5.1%) incident cardiovascular events. Among patients with a lower HbA1C or FPG, 15.6% and 16.3%, respectively, had a discordantly high TyG index and a greater risk of cardiovascular events compared with patients with a concordantly low TyG index after full adjustment (HR: 1.92, 95% CI 1.33-2.77; HR: 1.89, 95% CI 1.38-2.59; for HbA1C and FPG, respectively). Repeat risk estimation using high or low categories for FPG or HbA1C and diabetes status confirmed the results. CONCLUSIONS Patients with a discordantly high TyG index had a significantly greater risk of cardiovascular events regardless of diabetes status. The TyG index might be a better predictor of cardiovascular risk than FPG or HbA1C for patients with ACS undergoing PCI. This discordance may support better cardiovascular risk management regardless of diabetes status.

Abstract
BACKGROUND Iron deficiency (ID) is a known co-morbidity and a potential therapeutic target in heart failure. Whether ID is frequent also in ST-segment elevation acute myocardial infarction (STEMI) patients and is associated with worse in-hospital outcomes has never been evaluated. METHODS We defined ID as a serum ferritin < 100 μg/L or transferrin saturation < 20% at hospital admission. We assessed the association between ID and the primary endpoint (a composite of in-hospital mortality and Killip class ≥ 3). We explored the potential association between ID, circulating cell-free mitochondrial DNA (mtDNA), and cardiac magnetic resonance (CMR) parameters. RESULTS Four-hundred-twenty STEMI patients undergoing primary percutaneous coronary intervention (pPCI) were included. Of them, 237 (56%) had ID. They had significantly higher admission high-sensitivity troponin and mtDNA levels as compared to non-ID patients (145 ± 35 vs. 231 ± 66 ng/L, P < 0.001; 917 [404-1748] vs. 1368 [908-4260] copies/μL; P < 0.003, respectively). A lower incidence of the primary endpoint (10% vs. 18%, P = 0.01) was observed in ID patients (adjusted OR 0.50 [95% CI 0.27-0.93]; P = 0.02). At CMR (n = 192), ID patients had a similar infarct size (21 ± 18 vs. 21 ± 19 g; P = 0.95), but a higher myocardial salvage index (0.56 ± 0.30 vs. 0.43 ± 0.27; P = 0.002), and a smaller microvascular obstruction extent (3.6 ± 2.2 vs. 6.9 ± 3.9 g; P < 0.001). CONCLUSIONS Iron deficiency is frequent in STEMI patients, it is coupled with mitochondrial injury, and, paradoxically, with a better in-hospital outcome. This unexpected clinical result seems to be associated with a smaller myocardial reperfusion injury. The mechanisms underlying our findings and their potential clinical implications warrant further investigation.
