Association of ectatic non-infarct-related artery with 1-month stent thrombosis in patients with ST elevation myocardial infarction.

BACKGROUND: Ectatic infarct-related artery (IRA) has been shown to be associated with higher thrombus burden, no-reflow, stent thrombosis (ST) and major adverse cardiovascular events in patients with ST-elevation myocardial infarction (STEMI). The effect of ectatic non-IRA on ST without ectatic IRA is not known. We aimed to assess the effect of ectatic non-IRA presence on ST within 1 month after primary percutaneous intervention (pPCI) in patients with STEMI. METHODS: A total of 1541 patients with a diagnosis of STEMI and underwent pPCI between 2015 and 2020 were retrospectively included in the study. Patients with and without 1 month ST were compared. Penalised logistic regression method was used to assess the association between ST and candidate predictors due to the risk of overfitting. RESULTS: Median age of the study group was 56.5 (48.7 to 67.2) years. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score, ectatic non-IRA presence and use of tirofiban were significantly higher in the ST group (18.2±9.9 vs 15.1±9.9, p=0.03; 25% vs 7.2%, p<0.001; 54.2% vs 30.5%, p<0.001; respectively). Significantly higher thrombus aspiration (14.3% vs 6.7%, p=0.03) and lower stent implantation (67.7% vs 84%, p<0.001) rates were observed in ectatic IRA group compared with ectatic non-IRA group. In multivariable analysis, ectatic non-IRA presence was independently associated with 1-month ST (OR 4.01, 95% CI 1.86 to 8.63, p=0.01). CONCLUSION: Ectatic non-IRA presence without ectatic IRA in patients with STEMI increases the risk of ST within the first month of pPCI.

Effects of RAAS blocker use on AKI in elderly hypertensive STEMI patients with propensity score weighed method.

Studies reported conflicting results on the effect of renin-angiotensin-aldosterone system (RAAS) blocker use on acute kidney injury (AKI) in patients undergoing elective coronary angiography but association in elderly patients with ST-elevation myocardial infarction (STEMI) is not known. Also, there are limited data on the effect of inflammatory markers on AKI. We aimed to investigate the effects of RAAS blocker pretreatment and inflammatory markers on AKI in this population. A total of 471 patients were compared according to presence of RAAS blocker pretreatment at admission. Conventional and inverse probability weighed conditional logistic regression were used to determine independent predictors of AKI. Mean age of the study group was 75.4 ± 7.1 years and 29.1% of the patients were female. AKI was observed in 17.2% of the study population. Weighted conditional multivariable logistic regression analysis revealed that AKI was associated with baseline creatinine levels and C-reactive protein/albumin ratio (CAR) (OR 2.08, 95% CI = 1.13-3.82, p = .02 and OR 1.19, 95% CI = 1.01-1.41, p = .04, respectively). No significant association was found between RAAS blocker pretreatment and AKI. CAR and elevated baseline creatinine levels were independent predictors of AKI in this patient group.

Speckle tracking echocardiography in severe patient-prosthesis mismatch.

BACKGROUND: Although aortic valve replacement (AVR) when successfully performed boasts low mortality rates in selected patients, prosthesis-patient mismatch (PPM) can be found in the majority of these individuals. Limited research is available supporting the benefit of two-dimensional speckle tracking echocardiography (2D-STE) in patients with severe PPM. This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction. MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65 cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected and compared between the two groups of patients with severe PPM (n = 27) and those with normofunctional aortic prosthesis valve as a control group (n = 27). All patients underwent baseline echocardiography. Global longitudinal strain (GLS) and global circumferential strain (GCS) were evaluated by 2D-STE. RESULTS: When compared with controls, patients with severe PPM had significantly decreased GLS (18.6 ± 2.9 vs. 21.4 ± 2.1; p < 0.01) and GCS (17.2 ± 3.6 vs. 21.7 ± 2.1; p < 0.01) values. CONCLUSION: In addition to standard clinical and echocardiographic parameters, GLS and GCS suggest subclinical dysfunction and have incremental value in patients with severe PPM.

Spontaneous Right Coronary Artery Rupture and Acute Cardiac Tamponade in Behçet's Disease.

Coronary involvement in Behçet's disease is extremely rare and it can bring devastating consequences when it occurs. In this report, we present a 29-year-old male patient with Behçet's disease who developed rapidly changing and progressive coronary artery involvements under medical treatment.

Metabolic syndrome is associated with atrial electrical and mechanical dysfunction.

OBJECTIVE: In this study, we aimed to investigate the left atrial (LA) electrical and mechanical functions in patients with metabolic syndrome (MetS). SUBJECTS AND METHODS: The study population consisted of 87 patients with MetS and 67 controls. Intra-atrial and interatrial electromechanical delays (EDs) were measured with tissue Doppler imaging. P-wave dispersion (Pd) was calculated from the 12-lead electrocardiograms. LA volumes were measured echocardiographically by the biplane area-length method. RESULTS: Intra-atrial and interatrial EDs and Pd were significantly higher in patients with MetS (10.3 ± 6.3, 21.0 ± 11.5 and 41.7 ± 10.8) than in controls (7.4 ± 5.5, 12.3 ± 10.4 and 29.2 ± 7.4; p = 0.003, p < 0.001 and p < 0.001, respectively). The LA preatrial contraction volume and active emptying volumes were higher in this population, but the LA passive emptying fraction was lower. In the multivariate linear regression analysis, the presence of MetS, LA active emptying volume and left ventricular early diastolic (E) wave velocity/late diastolic (A) wave velocity (E/A) ratios were independent correlates of interatrial ED (p = 0.002, p = 0.001 and p = 0.025, respectively). CONCLUSIONS: This study showed that intra-atrial and interatrial EDs and Pd were prolonged and LA mechanical functions were impaired in patients with MetS.

Echocardiographic assessment of right ventricular function before and after surgery in patients with pectus excavatum and right ventricular compression.

BACKGROUND: We aimed to evaluate the effect of surgical repair on right ventricular (RV) function in patients with pectus excavatum (PE) and RV compression by Doppler echocardiography. MATERIALS AND METHODS: Twenty-three patients who were admitted to our hospital for surgical correction of PE between 2009 and 2012 were included in the study. After transthoracic echocardiographic evaluation, 16 patients with RV compression were enrolled. All patients were males (100%) with a mean age of 20.5 ± 5.6 years. Transthoracic echocardiography was repeated 1 month after surgery. Echocardiographic evaluation included the assessment of RV diastolic diameter, tricuspid annular plane systolic excursion (TAPSE), pulsed tissue Doppler systolic velocity (S'), RV isovolumic acceleration (RV IVA), systolic pulmonary artery pressure, left ventricular (LV) ejection fraction, and myocardial performance indexes of both the right and the left ventricles (Tei index). RESULTS: Following the surgery, the RV end-diastolic diameter, TAPSE, S', and RV IVA were found to be significantly increased in patients with PE. In addition, RV and LV Tei index significantly improved after surgical correction. CONCLUSIONS: RV function significantly improved after corrective surgery. Quantitative echocardiographic examination provides accurate estimation when deciding for corrective surgery and also should be used in the assessment of postoperative improvement.

Severity of periodontitis in patients with isolated coronary artery ectasia.

The concept that coronary artery ectasia (CAE) is an inflammatory-related disease has been increasingly recognized. Periodontitis induced low-grade chronic systemic inflammation has been shown to be associated with cardiovascular diseases. The aim of the present study was to evaluate the association between periodontitis and CAE.Thirty-two patients with isolated CAE, and 28 age, sex and smoking status-matched subjects with normal coronary arteries (NCA) underwent full dental examinations. Periodontal disease was evaluated using the following clinical parameters; number of remaining teeth, plaque index (PI), gingival index (GI), bleeding on probing (BOP), and pocket depth (PD).Cases and controls did not differ according to their baseline characteristics and prevalence of traditional cardiovascular risk factors. Patients with isolated CAE had higher periodontal indices when compared to subjects with NCA (PD: 3.6 ± 1.26 mm versus 2.3 ± 0.79 mm; GI: 2.29 ± 0.86 versus 1.43 ± 1.19; BOP (%): 52.18 ± 20.1 versus 27.8 ± 10.9, P < 0.001, P < 0.05 and P < 0.05, respectively). Moreover, in multivariate analysis higher values for PD were found to be significant predictors for the likelihood of having coronary ectasia.The results of the present study demonstrate for the first time that there is an association between periodontitis and isolated CAE.

Successful management of left main coronary artery thrombus with intracoronary thrombolysis.

The management of valvular heart diseases with mechanical valves has been performed for several years. Warfarin has been used in patients with mechanical heart valves to protect against thromboembolic complications; nevertheless, in these patients, thromboembolic event rates range from 0.5% to 1.7%. Acute occlusive embolism to the coronary arteries due to a mechanical valve is an uncommon occurrence. In this report, we present a case of a left coronary system occlusion due to thrombus embolization from a prosthetic aortic valve, which was successfully treated by thrombolytic therapy.

A case report of coronary artery aneurysm in a patient with Behçet's disease.

Behçet's disease (BD) is a multisystem vasculitis that may involve vessels of all sizes. Acute coronary syndrome (ACS) due to secondary involvement of BD is rare and its management less clear. In this case, a 29-year-old man admitted to the emergency room with ongoing chest pain was interned to the coronary care unit with a diagnosis of ACS. The patient had been diagnosed 1 year before with BD and had been without regular follow-up, despite the suggested use of cholchium. An immediate coronary angiography revealed a fresh thrombus image in the proximal segment of the right coronary artery (RCA), an aneurysm of the left anterior descending artery (LAD) at proximal segment, and a hemodynamically significant lesion following the aneurysm. Intervention was ended because of normal flow (TIMI III) of distal RCA. An intravenous infusion of glycoprotein IIb/IIIa receptor inhibitor (tirofiban) was administered, and a control angiography showed dissolution of a thrombus in RCA, but enlarged aneurysm of LAD and a new aneurysm in RCA.

Cardiovascular effects of abduction shoulder sling in elderly patients; is it really safe?

OBJECTIVE: The purpose of the prospective study is to investigate the cardiovascular effects of abduction shoulder sling (ASS) in elderly patients who underwent rotator cuff surgery. METHODS: The study included 49 consecutive patients older than 50 years (mean 59.3 ± 8.2 years) who underwent arthroscopic rotator cuff repair surgery and used ASS in postoperative period. All cases underwent Holter electrocardiographic monitoring before (24 h) and after (48 h) the operation. The Holter findings were read by an experienced cardiologist and a pause of longer than 3 s and heart rate of <40 bpm was evaluated as significant bradycardia. RESULTS: One patient (61-year-old male) described feeling faint (presyncope) which was confirmed with the Holter finding of a pause more than 3 s which occurred in the day time. Two other patients (52-year-old male, and 62-year-old female) reported severe dizziness (hypotensive attack) which required admission to a general practitioner. However, Holter findings were normal in these patients. These three cases were referred to cardiology department for evaluation of carotid hypersensitivity syndrome (CSH). CSH was confirmed with tests made with provocative maneuvers in a sitting position. CSH was defined as at least 3 s of asystole (cardio-inhibitor type) during carotid massage or systolic blood pressure falling below 50 mmHg (vaso-depressor type). All three patients were obese patients and BMI was higher than 30. CONCLUSIONS: ASS may trigger CSH in short necked and obese patients by exerting mechanical stimulation to the carotid sinus. These patients should be informed about symptoms and signs of CSH and educated on the proper use of ASS and correct positioning of shoulder strap. CSH should be kept in mind in patients who present with dizziness, presyncope and palpitation during the postoperative period.

Myocardial ischemia in severe aortic regurgitation despite angiographically normal coronary arteries.

Patients with severe aortic regurgitation frequently present with angina pectoris. The exact pathophysiology for angina in aortic regurgitation is not clear. Left ventricular hypertrophy and myocardial blood supply-demand mismatch have been the suggested mechanisms to explain ischemia. However, no conclusive clinical study exists to define the incidence of ischemia in patients with severe aortic regurgitation and normal coronary arteries. We, therefore, investigated the frequency of myocardial ischemia in relation to left ventricular hypertrophy or dilatation in patients with severe aortic regurgitation and normal coronary arteries. We reviewed the medical records of all patients (n = 311) with aortic valve replacement due to aortic regurgitation between 2007 and 2010. We selected subjects with normal coronary arteries (n =182) for the study purpose, and we identified 35 patients who underwent myocardial perfusion scintigraphy prior to the coronary angiography (19 female and 16 male subjects; age 45.0 ± 8.9 years). Left ventricular hypertrophy and dilatation were detected in 9 (26%) and 5 (14%) patients, respectively. Myocardial perfusion scintigraphy showed evidence of ischemia in 10 (29%) patients with normal coronary arteries. The presence of ischemia did not relate to the presence of left ventricular hypertrophy and/or dilatation. As a potential mechanism, aortic regurgitation causes backflow of blood from the aorta into the left ventricle, hence disturbs coronary flow dynamics. In conclusion, myocardial ischemia is common (nearly one-third) among patients with severe aortic regurgitation even in the absence of coronary obstruction, left ventricular hypertrophy and/or dilatation.

[Late diagnosis of corrected transposition of the great arteries in an elderly patient with coronary artery disease]. / Ileri yastaki koroner arter hastasinda geç tani konan dogustan düzelmis büyük arter transpozisyonu.

Congenitally corrected transposition of the great arteries (c-TGA) is a rare congenital heart disease usually diagnosed during childhood. Rarely, some patients remain undiagnosed and develop symptoms of heart failure during adulthood due to dysfunction of the left ventricle and systemic atrioventricular valve. We report on a 69-year-old male patient with a history of percutaneous coronary intervention and stent implantation for coronary artery disease and coronary artery anomaly, in whom diagnosis of c-TGA was missed.

Subclinical myocardial dysfunction in patients with complete recovery from peripartum cardiomyopathy: a long-term clinical strain-echocardiographic study.

PURPOSE: The aim of this study was to assess long-term left ventricular (LV) systolic function using 3D speckle tracking echocardiography in patients with complete LV recovery following peripartum cardiomyopathy (PPCM). METHODS: A total of 20 PPCM patients who exhibited LV recovery (ejection fraction ≥50%) in the follow-up period and 20 age-matched, healthy women were included in the study. Standard 2D echocardiographic examinations were performed. Global longitudinal strain and global circumferential strain were analyzed. RESULTS: Age, weight, body surface area, smoking, heart rate, and systolic and diastolic blood pressure were similar in both groups. Echocardiographic examination showed no significant difference between both groups. Only the global longitudinal strain (18.1 ± 2.7 vs 20.16 ± 1.7, p = 0.02) and global circumferential strain (22.1 ± 2.9 vs 24.4 ± 1.19, p = 0.01) were significantly lower in PPCM patients. The lowest values for longitudinal strain belonged to the basal and mid regions of anterior, anteroseptal and lateral walls in the PPCM patients. CONCLUSION: Subclinical myocardial damage may persist in PPCM patients with full LV systolic recovery. 3D Speckle Tracking strain analysis is a useful method for detecting subtle myocardial dysfunction.

The Role of Prophylactic Ipsilateral Distal Femoral Artery Cannulation in Preventing Periprocedural Peripheral Complications During Transcatheter Aortic Valve Implantation.

OBJECTIVE: Access site-related vascular complications are common complications of trans- catheter aortic valve replacement. In this study, we aimed to investigate the efficacy and safety of prophylactic cannulation of the ipsilateral distal femoral artery in the management of access site-related vascular complications. METHODS: One hundred sixty-four patients, who were evaluated by the Heart Team of our institution and found eligible for transcatheter aortic valve replacement procedure between January 2016 and August 2019, were included in this retrospective study. Patients were divided into two groups according to the management of peripheral complications. The antegrade crossover was used as bailout treatment in the first 70 patients. Prophylactic cannulation of the ipsilateral distal femoral artery was performed in the last 94 patients. These 2 groups were compared. RESULTS: Peripheral complications developed in 15 of the first 70 patients included in the study. The percutaneous intervention was unsuccessful in 4 of the patients who underwent bailout antegrade crossover. Peripheral complications developed in 14 of the last 94 patients in whom prophylactic cannulation of the ipsilateral distal femoral artery was performed, and all these patients were managed successfully with percutaneous intervention. CONCLUSION: Prophylactic cannulation of the ipsilateral distal femoral artery is a simple, effec- tive, and safe method in the management of access site-related vascular complications.

Successful Usage of FlexCath Steerable Catheter in Case of Atrial Septal Closure Device Comes Perpendicular to Interatrial Septum.

OBJECTIVE: Percutaneous closure of atrial septal defects is challenging in cases where the device is perpendicular to the septum during the procedure. Hence, different techniques, maneuvers, and auxiliary equipment may be required. We aimed to demonstrate the effectiveness of the FlexCath steerable catheter application in percutaneous closure of atrial septal defect cases in which the device was perpendicular to the septum. METHODS: Patients with atrial septal defect who presented to our clinic between January 2017 and December 2020 and were deemed eligible for percutaneous closure were included in the study. RESULTS: Atrial septal defects of 101 patients out of 110 patients were successfully closed using standard methods. Nine patients in whom it was seen if the device was perpendicular to the interatrial septum were successfully closed with FlexCath steerable catheter support. There was no statistically significant difference between patients in terms of age, gender, floopy rim, and multiple defects. In the group that was treated with FlexCath steerable catheter support, the aortic rim was smaller, and the defect diameter and the size of the atrial septal defects device were larger. The success of the procedure was 100% while using the flexcath steerable catheter in patients with the device perpendicular to the interatrial septum. There were no complica tions during the procedure. CONCLUSION: Percutaneous closure with FlexCath steerable catheter support in difficult cases with atrial septal defects was effective in those with the atrial septal closure device being per pendicular to the interatrial septum and was performed easily without any safety issues.

The effects of blood pressure lowering on P-wave dispersion in patients with hypertensive crisis in emergency setting.

Hypertensive emergency refers to a severe hypertension (HT) that is associated with new or progressive end-organ damage. In these clinical situations, blood pressure (BP) should be reduced immediately to prevent or minimize organ dysfunction. The present study evaluated the diagnostic value of two electrocardiographic indices in detecting patients, who are at risk for paroxysmal atrial fibrillation (PAF), in the setting hypertensive crisis. The study population consisted of 30 consecutive patients aged ≥40 years, who were admitted to the emergency room with hypertensive crisis. Electrocardiographic (ECG) recordings of the patients were performed before and after the treatment. The minimum (Pmin) and maximum (Pmax) P wave duration on ECG, and P-wave dispersion (P(d)), which was defined as the difference between Pmin and Pmax, were measured. The mean P(d) was 118.0 ± 32.1 and 94.0 ± 44.3 before and after the treatment, respectively. The decrease observed in the mean P(d) was statistically significant (p = 0.005). The mean Pmax was 214.7 ± 37.1 before the treatment, while it was 194.0 ± 47.3 after the treatment, and the difference was significant (p = 0.021). The mean Pmin was 96.7 ± 26.3 and 100.0 ± 41.0 before and after the treatment, respectively; however, the difference was not significant (p = 0.624). Pmax and P(d) display significant changes with acute treatment of HT. There is a need for larger prospective studies to clearly elucidate the diagnostic value of ECG indices, Pmax and P(d) as indicators of future PAF.

[Coronary artery ectasia: clinical and angiographical evaluation]. / Koroner arter ektazisi: klinik ve anjiyografik degerlendirme.

OBJECTIVES: We investigated the prevalence, distribution, risk factors, and prognosis of coronary artery ectasia (CAE) in patients undergoing coronary angiography for suspected coronary artery disease (CAD). STUDY DESIGN: Of 4,119 patients undergoing elective coronary angiography between 2003 and 2005, 173 patients (139 males, 34 females; mean age 61+/-11 years) had CAE, with a prevalence of 4.2%. Distribution of CAE was made according to the classification of Markis et al. The results were compared with those of 145 control patients (115 males, 30 males; mean age 61+/-10 years) who had CAD but not CAE. Following coronary angiography, treatment was designed as aortocoronary bypass (n=3), percutaneous coronary intervention (n=36), and medical therapy (n=98). The mean follow-up was 34.2+/-2.5 months. RESULTS: Among CAE patients, there was a marked male preponderance with 80.3%. Coronary ectasia was isolated in 46 patients (26.6%) and was associated with significant coronary artery stenoses in 127 patients (73.4%). The only significant difference with the control group with respect to baseline features was the higher frequency of hypertension in the CAE group (p=0.002). Coronary ectasia involved a single vessel in 67.1%, two vessels in 24.9%, and three vessels in 8.1%, with the right coronary artery being the most common localization (50.9%). The diameters of ectatic coronary arteries ranged from 3.2 mm to 9.7 mm (mean 5.6 mm). According to the classification of Markis et al., the majority of patients (64.2%) had type IV ectasia. In multiple regression analysis, hypertension was independently associated with CAE (OR: 0.378; 95% CI: 0.211-0.678; p=0.001). Mortality occurred in nine patients (5.2%). The annual mortality rates were 1.5%, 2.1%, and 2.9% with medical therapy, percutaneous coronary intervention, and aortocoronary bypass, respectively. CONCLUSION: Our findings suggest that further prospective studies focus on the dependent relationship between hypertension and CAE, and on marked coexistence of CAD and CAE.

Assessment of Atrial Conduction Times in Patients with Newly Diagnosed Parkinson's Disease.

BACKGROUND: An increased risk of ischemic stroke has been reported in patients with Parkinson's disease (PD). Atrial fibrillation (AF) is strongly associated with ischemic stroke. Prolonged atrial electromechanical delay (EMD) is an independent predictor for the development of AF. AIMS: The aim of the present study was to evaluate the atrial conduction parameters in patients with PD and to assess their relation with the severity of PD. STUDY DESIGN: We prospectively enrolled 51 consecutive patients with newly diagnosed PD and 31 age- and sex-matched non-PD subjects. METHODS: To assess atrial electromechanical coupling (PA), the time intervals from the onset of p wave on ECG to the late diastolic wave at the septal (PAs) and lateral (PAl) mitral annulus and lateral tricuspid annulus (PAt) were measured on Tissue Doppler Echocardiography (TDE). The difference between PAs-PAl, PAs-PAt, and PAl-PAt were defined as left intra-atrial, right intra-atrial, and interatrial EMD, respectively. P-wave dispersion (PWD) was calculated from the 12-lead ECG. RESULTS: PWD, PAs, PAl, and PAt durations were significantly prolonged in the PD group (all p < 0.001). Interatrial, right, and left intra-atrial EMD were also significantly longer in PD patients (p < 0.001, p < 0.001 and p=0.002, resp.). There were significant positive correlations between disease severity (UPDRS score) and PWD (r=0.34, p=0.041), left intra-atrial (r=0.39, p=0.005), and interatrial EMD (r=0.35, p=0.012). By multivariate analysis, PWD (OR: 1.13, 95% CI: 1.02-1.25; p=0.017), LA volume index (OR: 1.19, 95% CI: 1.02-1.37; p=0.021), left intra-atrial (OR: 1.12, 95% CI: 1.01-1.24; p=0.041), and interatrial EMD (OR: 1.08, 95% CI: 1.01-1.16; p=0.026) were found as independent predictors of PD. CONCLUSION: Atrial conduction times were longer and correlated with the severity of disease in PD patients. Prolonged inter- and intra-atrial-EMD intervals were also found as independent correlates of PD. These findings may suggest an increased predisposition to atrial fibrillation in PD.

Value of the neutrophil-to-lymphocyte ratio in predicting left ventricular recovery in patients with peripartum cardiomyopathy.

OBJECTIVE: The aim of this study was to assess the value of the neutrophil-to-lymphocyte ratio (NLR) in predicting left ventricular (LV) recovery in patients with peripartum cardiomyopathy (PPCM). METHODS: Patients with PPCM (n = 40), who were admitted to our tertiary reference hospital between 2007 and 2015 were retrospectively analyzed. All patients were followed-up for at least 12 months after the diagnosis. All patients had standard echocardiographic examination at baseline and the last follow-up visit. Recovery of LV function was defined as the presence of LV ejection fraction (EF) >45%. Data on blood parameters were also collected at baseline. Univariate and multivariate analysis were used to assess the significant predictive variables for persistent LV systolic dysfunction. RESULTS: Of the patients 21 (52.5%) did not recover LV function at the last follow-up visit (nonrecovery group), while 19 of the patients (47.5%) exhibited LV recovery (recovery group). The LV EF and fractional shortening (FS) were significantly lower in the nonrecovery group. The baseline LV end-diastolic diameter, LV end-systolic diameter (LVESD) and systolic pulmonary arterial pressure were significantly increased in the nonrecovery group. The NLR, C­reactive protein and troponin levels were significantly higher in the nonrecovery group. In multivariate logistic regression analysis only NLR and LVESD were identified as independent predictors of persistent LV systolic dysfunction in patients with PPCM (p = 0.020 and p = 0.009 respectively). CONCLUSION: Elevated NLR and increased LVESD were independent prognostic factors in predicting persistent LV dysfunction in patients with PPCM. The NLR might assist in identifying high risk patients with PPCM.
