Usability of myocardial work parameters in demonstrating myocardial involvement in INOCA patients.

BACKGROUND: Myocardial work (MW) is a novel echocardiographic modality, which has been shown to have diagnostic and prognostic values in patients with cardiovascular diseases, patients with obstructive coronary artery disease, in particular. However, only a handful of studies have examined the MW analysis in ischemia with nonobstructive coronary artery (INOCA) disease. This study, therefore, aimed to detect the early left ventricular involvement in INOCA patients diagnosed by an invasive coronary angiography performing the MW analysis. METHODS: This study included a total of 119 patients with nonobstructive coronary artery disease diagnosed by invasive coronary angiography, who were checked for prior ischemia tests performing myocardial perfusion scintigraphy. Out of these 119 patients, 49 patients developed ischemia (i.e., ischemic group) diagnosed using cardiac single-photon emission computed tomography, whereas 70 patients did not (i.e., nonischemic group). The subjects were divided into three groups based on the global MW tertiles. The groups were compared in terms of the conventional, longitudinal strain, and MW findings by conducting echocardiographic examinations. RESULTS: The study subjects were divided into three groups based on the global constrictive work (GCW) value. The three groups were not statistically different in terms of the mean age of the patients (53.0 ± 12 vs. 52.4 ± 13.3 vs. 52.1 ± 12.3; p = 0.96). Furthermore, the three groups were not statistically different regarding the gender, height, weight, and laboratory parameters of the patients except albumin. There was no statistically difference among the tertiles of GCW groups in the measurements of cardiac chambers, LA diameter, interventricular septum, E wave, and A wave. Also, there was no statistical difference in tissue Doppler recordings. The parameters associated with MW were examined, three groups were not statistically different in terms of the global waste work (GWW) (116 ± 92, 122 ± 73, 135 ± 62, p = 0.52, respectively). In contrast, the three groups were different regarding the Global work index (GWI) (1716 ± 300, 1999 ± 130, 2253 ± 195, p < 0.001, respectively), GCW (1888 ± 206, 2298 ± 75, 2614 ± 155, p < 0.001, respectively), and Global work efficiency parameters (92.8 ± 3.6, 94.4 ± 3.2, 95.1 ± 1.8 p = 0.004, respectively). CONCLUSION: It was concluded that the MW parameters GCW and GWI may have been used for predicting INOCA in patients.

Transcatheter Closure or Surgery for Symptomatic Paravalvular Leaks: The Multicenter KISS Registry.

BACKGROUND: The optimal treatment of symptomatic paravalvular leak (PVL) remains controversial between transcatheter closure (TC) and surgery. This large-scale study aimed to retrospectively evaluate the long-term outcomes of the patients who underwent reoperation or TC of PVLs. METHODS AND RESULTS: A total of 335 (men, 209 [62.4%]; mean age, 58.15±12.77 years) patients who underwent treatment of PVL at 3 tertiary centers between January 2002 and December 2021 were included. Echocardiographic features, procedure details, and in-hospital or long-term outcomes were assessed. The primary end point was defined as the all-cause death during follow-up. The regression models were adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The initial management strategy was TC in 171 (51%) patients and surgery in 164 (49%) cases. Three hundred cases (89.6%) had mitral PVL, and 35 (10.4%) had aortic PVL. The mean left ventricular ejection fraction was 52.03±10.79%. Technical (78.9 versus 76.2%; P=0.549) and procedural success (73.7 versus 65.2%; P=0.093) were similar between both groups. In both univariate and multivariable logistic regression analysis, the in-hospital mortality rate in the overall population was significantly higher (15.9 versus 4.7%) in the surgery group compared with the TC group (unadjusted odds ratio, 3.13 [95% CI, 1.75-5.88]; P=0.001; and adjusted odds ratio (inverse probability-weighted), 4.55 [95% CI, 2.27-10.0]; P<0.001). However, the long-term mortality rate in the overall population did not differ between the surgery group and the TC group (unadjusted hazard ratio [HR], 0.86 [95% CI, 0.59-1.25]; P=0.435; and adjusted HR (inverse probability-weighted), 1.11 [95% CI, 0.67-1.81]; P=0.679). CONCLUSIONS: The current data suggest that percutaneous closure of PVL was associated with lower early and comparable long-term mortality rates compared with surgery.

Thromboembolic risk scores in patients with non-obstructive coronary architecture with and without coronary slow flow: A case-control study.

AIM: Coronary slow flow phenomenon (CSFP) detected on coronary angiography (CA) has been related to poor prognosis. We sought to examine the relationship between thromboembolic risk scores, routinely used in cardiology practice, and CSFP. METHODS: This single-center, retrospective, case-control study comprised 505 individuals suffering from angina and had verified ischemia between January 2021 and January 2022. Demographic and laboratory parameters were obtained from the hospital database. The following risk scores were calculated; CHA2DS2-VASc, M-CHA2DS2-VASc, CHA2DS2-VASc-HS, R2-CHA2DS2-VASc, M-R2-CHA2DS2-VASc, ATRIA, M-ATRIA, M-ATRIA-HSV. The overall population was divided into two groups; coronary slow flow and coronary normal flow. Multivariable logistic regression was performed to compare risk scores between patients with and without CSFP. Pairwise comparisons were then undertaken to test performance in determining CSFP. RESULTS: The mean age was 51.7 ± 10.7 years, of whom 63.2% were male. CSFP was detected in 222 patients. Those with CSFP had higher rates of male gender, diabetes, smoking, hyperlipidemia, and vascular disease. All scores were higher in CSFP patients. Multivariable logistic regression analysis found that CHA2DS2-VASc-HS score was the most powerful determinant of CSFP among all risk schemes (for each one-point increase in score OR = 1.90, p < 0.001; for score of 2-3 OR = 5.20, p < 0.001; for score of >4 OR = 13.89, p < 0.001). Also, the CHA2DS2-VASc-HS score provided the best discriminative performance, with a cut-off value of ≥2 in identifying CSFP (AUC = 0.759, p < 0.001). CONCLUSION: We showed that thromboembolic risk scores may be associated with CSFP in patients with non-obstructive coronary architecture who underwent CA. The CHA2DS2-VASc-HS score had the best discriminative ability.

Comparison of thromboembolic risk scores for evaluating in-hospital events of COVID-19 patients.

Aim: To compare the effectiveness of thromboembolic risk scores in determining in-hospital events of COVID-19 patients. Methods: This retrospective study included a total of 410 consecutive COVID-19 patients. Scores including CHA2DS2-VASc-HS (congestive heart failure, hypertension, age, diabetes mellitus, stroke/transient ischemic attack, vascular disease, sex, hyperlipidemia, smoking); modified R2CHA2DS2-VASc (CHA2DS2-VASc plus renal function), m-ATRIA (modified Anticoagulation and Risk Factors in Atrial Fibrillation score), ATRIA-HSV (ATRIA plus hyperlipidemia, smoking and vascular disease) and modified ATRIA-HSV were calculated. Participants were divided by in-hospital mortality status into two groups: alive and deceased. Results: Ninety-two (22.4%) patients died. Patients in the deceased group were older, predominantly male and had comorbid conditions. CHA2DS2-VASc-HS (adjusted odds ratio [aOR]: 1.31; p = 0.011), m-R2CHA2DS2-VASc (aOR: 1.33; p = 0.007), m-ATRIA (aOR: 1.18; p = 0.026), ATRIA-HSV (aOR: 1.18; p = 0.013) and m-ATRIA-HSV (aOR: 1.24; p = 0.001) scores were all associated with in-hospital mortality. m-R2CHA2DS2-VASc and modified ATRIA-HSV had the best discriminatory performance. Conclusion: We showed that m-R2CHA2DS2-VASc and m-ATRIA-HSV scores were better than the rest in predicting mortality among COVID-19 patients.

COVID-19 continues to be a pandemic that threatens human health all over the world. The main aim of our study was to examine the relationship between risk scores routinely used to determine the probability of clot formation in various cardiovascular diseases and in-hospital deaths of COVID-19 patients. The study comprised 410 adult patients hospitalized with a confirmed diagnosis of COVID-19. The clinical and laboratory data were obtained from the hospital registry system. All risk scores in the study were significantly greater in people who died from COVID-19 than in those who survived. Moreover, scoring systems that include kidney function outperformed the rest in determining in-hospital death. As a result, we discovered that specific risk scores used to indicate a person's likelihood of developing clot formation at a routine cardiology clinic are connected to in-hospital deaths among hospitalized COVID-19 patients.

The value of PRECISE-DAPT score and lesion complexity for predicting all-cause mortality in patients with NSTEMI.

BACKGROUND: We aimed to evaluate the prognostic effects of stroke risk scores (SRS), SYNTAX score (SX score), and PRECISE-DAPT score on mortality in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Three hundred forty-three patients hospitalized with a diagnosis of NSTEMI and underwent coronary angiography (CAG) between January 1, 2022, and June 1, 2022, were included retrospectively in this single-center study. Patients' demographic, clinical and routine biochemical parameters were recorded. The scores (CHADS2, CHA2DS2-VASc, R2CHA2DS2-VASc, ATRIA, SX score, PRECISE-DAPT) of each patient were calculated. Participants were then divided into two groups by in-hospital status; all-cause mortality (+) and all-cause mortality (-). RESULTS: Overall, the mean age was 63.5 ± 11.8 years, of whom 63.3% (n = 217) were male. In-hospital mortality occurred in 31 (9.3%) patients. In the study population, those who died had significantly higher SX (p < 0.001), PRECISE-DAPT (p < 0.001), and ATRIA (p = 0.002) scores than those who survived. In logistic regression analysis, PRECISE-DAPT score [Odds ratio (OR) = 1.063, 95% CI 1.014-1.115; p = 0.012] and SX score [OR: 1.061, 95% CI 1.015-1.109, p = 0.009] were found to be independent predictors of in-hospital all-cause mortality among NSTEMI patients. In ROC analysis, the PRECISE-DAPT score performed better discriminative ability than the SX score in determining in-hospital mortality [Area under the curve = 0.706, 95% CI 0.597-0.814; p < 0.001]. CONCLUSIONS: During the hospital stay, both PRECISE-DAPT and SX scores showed better performance than SRS in predicting all-cause mortality among NSTEMI patients undergoing CAG. Aside from their primary purpose, both scores might be useful in determining risk stratification for such patient populations.

The pattern of dyslipidemia among Somali type 2 diabetic patients: a cross-sectional study.

BACKGROUND: Diabetes mellitus (DM) is a major public health concern. This study aims to determine frequency, pattern, and potential determinants of dyslipidemia among adults with type 2 DM (T2DM) at Somalia's only diabetes outpatient clinic. METHODS: Five hundred twenty-nine consecutive patients with T2DM who applied to our outpatient clinic between January 2020 and June 2020 were included in this cross-sectional hospital-based study. Demographic characteristics of participants, including lipid panel, were extracted from the registry system. Correlation analysis was performed between lipid profile and related parameters. Multivariate binary logistic regression models were used to identify independent determinants of dyslipidemia for further analysis. RESULTS: The overall population's mean age was 51.9 ± 12.2 years, with 177 (33.5%) males. Total and atherogenic dyslipidemias were found in 92.8% and 24.8%, respectively. The most common isolated pattern of dyslipidemia was high non-high-density lipoprotein cholesterol (non-HDL-C) (82.8%), followed by high low-density lipoprotein cholesterol (LDL-C) (72.6%), high total cholesterol (TC) (54.3%), and low HDL-C (48.3%). Females were found to have a higher prevalence of high TC (63.4% vs. 54.2%, p = 0.043) and lower HDL-C (57.4% vs. 46.3%, p = 0.016). High LDL-C with low HDL-C was the most common pattern among combined type dyslipidemias (18.1%), followed by high LDL-C with high triglyceride (TG) (17.8%), as well as low TG with low HDL-C (3.6%). Females had a higher proportion of high LDL-C with low HDL-C than males (20.3% vs. 13.6%, p = 0.036). Age, gender, body mass index, central obesity, spot urinary proteinuria, fasting blood glucose, poor glycemic control, creatinine, and Hs-CRP were all associated with different dyslipidemia patterns in multivariate logistic regression analyses. CONCLUSIONS: We found that the prevalence of dyslipidemia, especially atherogenic patterns, was extremely high among Somali T2DM patients. An enhanced health policy should, therefore, be established to detect, treat and prevent dyslipidemia.

The Impact of Lesion Complexity and the CHA2DS2-VASc Score on Spontaneous Reperfusion in Patients with ST-Segment Elevation Myocardial Infarction.

Background: In patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI), a patent infarct-related artery (IRA) on initial angiography is defined as spontaneous reperfusion (SR). Objective: The present study aimed to determine the impact of lesion complexity and the CHA2DS2-VASc score on SR in patients with STEMI. Methods: A total number of 1,641 consecutive patients with STEMI undergoing primary PCI were assessed for this study. Patients were divided into 2 groups, those with SR, SR(+) (n = 239), and those without SR, SR(-) (n = 1402), according to their initial angiography and SR status. CHA2DS2-VASc scores were calculated for all patients. The lesion complexity of coronary artery disease was assessed with the SYNTAX score. Results: The CHA2DS2-VASc and SYNTAX scores were significantly lower in the SR(+) group compared to the SR(-) (mean CHA2DS2-VASc, 1.36 ± 0.64 vs. 2.01 ± 0.80, p < 0.001; mean SYNTAX score, 15.51 ± 5.94 vs. 17.08 ± 8.29, p < 0.001). After the multivariate regression analysis, a lower CHA2DS2-VASc (OR = 0.288, p < 0.001), SYNTAX score (OR = 0.920, p=0.007), uric acid (OR = 0.868, p=0.005), CRP (OR = 0.939, p=0.001), BNP (OR = 0.998, p=0.004), and troponin (OR = 0.991, p=0.001) were independent predictors of SR. In-hospital mortality rates were significantly lower in the SR(+) group compared to the SR(-) (0% vs. 6.7%, p < 0.001). Conclusion: Our study demonstrated that lesion complexity and the CHA2DS2-VASc score are independently associated with spontaneous reperfusion.

Pulmonary hypertension among maintenance hemodialysis patients in Somalia: a hospital-based observational study.

BACKGROUND: This study aims to examine the prevalence and related factors of pulmonary hypertension (PHT) in patients on hemodialysis (HD) at the only referral institution in Somalia. A total of one hundred and forty-three patients  who had received regular HD therapy for at least three months and underwent transthoracic echocardiography (TTE) were included in the study. Patients with a systolic pulmonary artery pressure (sPAP) value > 35 mmHg at rest on TTE were considered having PHT. The relationship of TTE parameters, demographic, and clinic characteristics of participants with PHT were evaluated. RESULTS: The number of patients with PHT was 73 (51%). The mean age was 54.2 ± 18.4 years. The majority of patients were 65 years of age or older. (n: 46, 32.2%) and 65 (45.5%) were male. Median sPAP was found to be 35 mmHg. Systolic pulmonary artery pressure was positively correlated with right atrium (RA) diameter (r: 0.6, p < 0.001) and negatively correlated with left ventricular ejection fraction (LVEF) (r: - 0.4, p < 0.001). In addition, LVEF, RA diameter, presence of pericardial effusion (PE) were found to be independent predictors of PHT. CONCLUSIONS: Pulmonary hypertension has a relatively high prevalence in end-stage renal disease (ESRD) patients on regular HD. Besides, the presence of PE and certain right and left heart parameters were independently associated with PHT.

The association of dynamic thiol-disulphide balance with white-coat hypertension.

OBJECTIVE: Dynamic thiol-disulphide homeostasis is an indicator of the antioxidant system that interacts early with the oxidative environment. This study aimed to assess the dynamic thiol/disulphide balance in individuals with white-coat hypertension (WCH). METHODS: This cross-sectional study included a total of 117 individuals who presented to our outpatient cardiology clinic. Seventy patients were diagnosed with WCH. All blood samples were obtained from the patients after a minimum of 8 h of fasting, centrifuged immediately, stored in Eppendorf tubes, and protected at -80°C. RESULTS: The two groups were well-balanced in terms of age, gender, and BMI. Native thiol and total thiol levels were lower in the WCH group than in normotensive individuals. However, disulphide levels were higher in the former. Serum disulphide concentration positively correlated with 24-h SBP, and 24-h DBP. In backward stepwise logistic regression analysis, serum disulphide [odds ratio (OR) = 1.165 (1.089-1.245), 95% confidence interval (CI), P < 0.001] and serum total thiol levels [OR = 0.992 (0.984-1.000), 95% CI, P = 0.050] were independently associated with WCH. CONCLUSION: We demonstrated that dynamic thiol/disulphide balance shifted strongly towards disulphide formation due to thiol oxidation in patients with WCH.

HATCH Score for Predicting Mortality in COVID-19 Patients.

Background: We aimed to evaluate the relationship between HATCH score [hypertension, age >75 yr, previous transient ischemic attack (TIA) or stroke (doubled), chronic obstructive pulmonary disease, heart failure (doubled)] and in-hospital mortality in COVID-19 patients. Methods: Overall, 572 COVID-19 patients hospitalized between Mar 15 and Apr 15, 2020, were included in this multicenter retrospective study, in Turkey. The HATCH score of each patient was calculated. Mortality results were followed for 50 days. The patients were divided into 2 groups developing mortality (n=267) and non-mortality (n=305). Clinical outcomes were defined as in-hospital mortality improvement status. Results: HATCH scores in non-survivors of COVID-19 were significantly higher than in survivors (P<0.001). In logistic regression analysis, HATCH score (OR: 1.253, 95% CI: 1.003-1.565; P=0.047), platelet count (OR: 0.995, 95% CI: 0.993-0.998; P<0.001), C-reactive protein level (OR: 1.010, 95% CI: 1.007-1.013, P<0.001) and estimated glomerular filtration ratio (eGFR) level (OR: 0.963, 95% CI: 0.953-0.973; P<0.001) were independent predictors of in-hospital mortality in COVID-19 patients. Conclusion: The HATCH score is useful in predicting in-hospital mortality in patients hospitalized with COVID-19.

The relationship between serum rheumatoid factor level and SYNTAX score I in patients with acute myocardial infarction.

OBJECTIVE: Rheumatoid factor (RF) has been associated with an increased likelihood of developing coronary artery disease and cardiovascular mortality. This study aimed to evaluate the relationship between serum RF levels and SYNTAX score I (SSI) in patients with acute myocardial infarction. METHODS: This study included 418 consecutive patients who were diagnosed with acute myocardial infarction and underwent coronary angiography. The baseline serum RF levels of all patients were measured. The study population was divided into 2 groups, namely, ST-segment elevation myocardial infarction (STEMI) group (218 patients) and non-ST-segment elevation myocardial infarction (NSTEMI) group (200 patients). Each group was further divided into 2 subgroups, namely, SSI ≤22 group and SSI >22 group. RESULTS: In the STEMI group, RF levels were significantly higher in the SSI >22 group than that in the SSI ≤22 group (13.0 IU/mL [7.0-51.0 IU/mL] versus 11.0 IU/mL [4.0-37.0 IU/mL], respectively, p=0.002). In the NSTEMI group, RF levels were significantly higher in the SSI >22 group than that in the SSI ≤22 group (15.5 IU/mL [8.0-69.5 IU/mL] versus 13.0 IU/mL [4.0-36.0 IU/mL, respectively], p<0.001). Forward conditional logistic regression analysis demonstrated that neutrophil-to-lymphocyte ratio, total cholesterol level, positive RF, and left ventricular ejection fraction were independently associated with intermediate and high SSI in patients with STEMI. Furthermore, cardiac troponin T levels and positive RF were independently associated with intermediate and high SSI in patients with NSTEMI. CONCLUSION: Serum RF concentrations are independently associated with SSI in patients with acute myocardial infarction.

Spectrum of cardiovascular diseases at a referral tertiary care hospital in Somalia, Mogadishu: an echocardiographic study.

BACKGROUND: To investigate the frequencies and patterns of cardiovascular diseases (CVDs), including rheumatic and congenital heart diseases, among patients with abnormal hearts assessed by echocardiographic examination. METHODS: This retrospective, descriptive registry reviewed abnormal echocardiographic findings of 1140 patients aged 0-100 years who were admitted to the cardiology outpatient clinic at a tertiary training institution in Mogadishu. RESULTS: Hypertensive heart disease (HHD) (n:454, 39.8%), valvular heart disease (VHD) (n:395, 34.6%), and heart failure with reduced ejection fraction (HFrEF) (n:351, 30.8%) were the most frequent comorbidities. Congenital heart diseases (CHDs) were detected in 151 (13.2%) of the patients, with the most common ones including atrial septal defect (ASD) (n:37, 3.2%) and ventricular septal defect (VSD) (n:26, 2.3%). Rheumatic heart disease (RHD) was observed in 84 (7.4%) patients, among whom the most common age range was 16-30 years (40.5%), followed by 31-45 years (31%) and 0-15 years (15.5%). Mitral insufficiency (n:541, 47.5%) was detected as the most frequent VHD, followed by aortic insufficiency (n:437, 38.3%), and tricuspid insufficiency (n:264, 23.2%) and mitral valve stenosis (n:39, 3.4%) was the least common VHD. CONCLUSION: In the present study, we found that HHD was the most common comorbidity, followed by VHD, and HFrEF. Moreover, the most common VHD was mitral insufficiency and the most common CHD was ASD.

Prognostic significance of temporal changes of lipid profile in COVID-19 patients.

BACKGROUND: COVID-19 is a multisystemic disease that affects many organs and has metabolic effects. AIMS: This study aims to investigate the effect of the temporal changes of lipid levels on the prognosis during the course of the disease. STUDY DESIGN: Retrospective cross-sectional study. METHODS: For this single-center study, data of patients who were treated for COVID-19 were collected. Fasting lipid parameters including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG) levels were collected within 24 h of hospitalization. For investigation of temoral changes in lipid parameters, the results of the same parameters in the one-year period before COVID-19 were collected from medical records. A total number of 324 eligible COVID-19 patients were included in this study. The association of changes of lipid parameters with COVID-19 symptom severity and in-hospital mortality were investigated. RESULTS: The mean age of the severe group (n = 139) was 65.4 ± 15.5 years, and 60% were male. TC, LDL-C and HDL-C levels were significantly lower compared to pre-COVID measurements in the study population. Multiple linear regression analysis determined age, acute kidney injury, hs-Troponin, D-dimer, temporal changes in TC, and TG levels were determined as independent predictors for the development of COVID-19 mortality. CONCLUSION: Our findings showed that temporal changes in lipid parameters before and after COVID-19 may be associated with mortality and in-hospital adverse outcomes.

Subacute lower extremity arterial thrombosis; early outcomes of catheter directed thrombolysis with alteplase and importance of malnutrition assessed by CONUT score.

OBJECTIVE: In this study, we aimed to report early outcomes of catheter-directed thrombolysis (CDT) with alteplase in patients with subacute limb ischemia and to assess whether there is a link between malnutrition (determined by Controlling Nutritional Status [CONUT] score) and response to thrombolysis and bleeding. METHODS: This was a retrospective study conducted between 2007 and 2020 with 118 patients with Rutherford class 3 (34.7%), class 4 (40.7%), and class 5 (24.6%) symptoms owing to infraaortic subacute thrombotic occlusion who were treated with catheter-directed thrombolysis. RESULTS: Immediate technical success (Thrombolysis in Myocardial Infarction [TIMI] grade 2/3) was achieved in 56%, overall technical success after all adjunctive procedures was seen in 83.9%. Clinical success was obtained in 74.5% within 30 days. Major bleeding occurred in 11.8%. When we excluded access site hematomas, the rate of major bleeding was 5.1%. In-hospital mortality rate was 5.1%, and the amputation rate within 30 days was 12.7%. Any-degree malnutrition was detected in 48.3% according to CONUT score (≥2). Any-degree malnutrition was associated with failed thrombolysis and bleeding. The CONUT score predicted insufficient lytic response even after adjustment for confounding factors; however, serum C-reactive protein or neutrophil/lenfosit ratio did not. Other predictors of immediate technical failure after thrombolysis were symptom duration, Rutherford class 4/5 symptoms, and worsened distal runoff. CONCLUSION: In patients with subacute limb ischemia, CDT combined with adjunctive interventions was effective in many patients at the expense of a substantial risk of bleeding and death. Malnutrition was associated with insufficient lytic response and bleeding. Physicians should be aware of malnutrition and consider the nutritional status of patients with limb ischemia when selecting appropriate treatment.

Extracorporeal cardiopulmonary resuscitation in-hospital cardiac arrest due to acute coronary syndrome.

BACKGROUND: The aim of this study was to analyze the effect of extracorporeal cardiopulmonary resuscitation on survival and neurological outcomes in in-hospital cardiac arrest patients. METHODS: Between January 2018 and December 2020, a total of 22 patients (17 males, 5 females; mean age: 52.8±9.0 years; range, 32 to 70 years) treated with extracorporeal cardiopulmonary resuscitation using veno-arterial extracorporeal membrane oxygenation support for in-hospital cardiac arrest after acute coronary syndrome were retrospectively analyzed. The patients were divided into two groups as those weaned (n=13) and non-weaned (n=9) from the veno-arterial extracorporeal membrane oxygenation. Demographic data of the patients, heart rhythms at the beginning of conventional cardiopulmonary resuscitation, the angiographic and interventional results, survival and neurological outcomes of the patients before and after extracorporeal cardiopulmonary resuscitation were recorded. RESULTS: There was no significant difference between the groups in terms of comorbidity and baseline laboratory test values. The underlying rhythm was ventricular fibrillation in 92% of the patients in the weaned group and there was no cardiac rhythm in 67% of the patients in the non-weaned group (p=0.125). The recovery in the mean left ventricular ejection fraction was significantly evident in the weaned group (36.5±12.7% vs. 21.1±7.4%, respectively; p=0.004). The overall wean rate from veno-arterial extracorporeal membrane oxygenation was 59.1%; however, the discharge rate from hospital of survivors without any neurological sequelae was 36.4%. CONCLUSION: In-hospital cardiac arrest is a critical emergency situation requiring instantly life-saving interventions through conventional cardiopulmonary resuscitation. If it fails, extracorporeal cardiopulmonary resuscitation should be initiated, regardless the underlying etiology or rhythm disturbances. An effective conventional cardiopulmonary resuscitation is mandatory to prevent brain and body hypoperfusion.

The relationship between CHA2DS2-VASc score and isolated coronary artery ectasia.

INTRODUCTION: Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation of the epicardial coronary arteries. We aimed to elucidate the relationship between the CHA2DS2-VASc score and CAE. METHODS: The study population consisted of 122 patients with isolated CAE and 87 sex- and age-matched control subjects. The demographic, clinical, and laboratory profiles and CHA2DS2-VASc scores of patients with CAE and the control group were compared. The Markis classification was used to determine the extent of CAE. Coronary arteries in which ectasia was localized were identified. CHA2DS2-VASc scores were calculated for all patients. Parameters predicting the development of CAE were analyzed with multivariate logistic regression. RESULTS: The majority of patients with CAE were male (76, 62%) and their mean age was 58.4 ± 8.3. The CHA2DS2-VASc score of the CAE group was significantly higher than that of the control group (2.41 ± 1.12 vs 1.52 ± 0.73, P < 0.001). Multivariate regression analysis showed that the CHA2DS2-VASc score (odds ratio [OR] = 1.607, P = 0.004), left ventricular ejection fraction (OR = 0.953, P = 0.044), uric acid (OR = 1.569, P = 0.003), white blood cell count (OR = 1.001, P < 0.001), highly sensitive C-reactive protein level (OR = 1.115, P = 0.010), and smoking (OR = 2.019, P = 0.043) were independent predictors of CAE. CONCLUSION: High CHA2DS2-VASc scores were associated with isolated CAE; therefore, the score might be a useful predictor of coronary thrombus development in patients with isolated CAE.

Alteration of serum biomarkers in patients with hypertrophic cardiomyopathy with and without atrial fibrillation.

Aim: We sought to determine the relationship between presence of atrial fibrillation (AF) and serum biomarkers, including native thiol (antioxidant), disulphide/native thiol ratio, Hs-CRP and high-sensitivity Troponin-I (Hs-TnI) in hypertrophic cardiomyopathy (HCM). Materials & methods: We enrolled consecutive 121 HCM outpatients without AF and 40 HCM outpatients with AF. A 12-lead electrocardiogram, transthoracic echocardiography and 24/48-h ambulatory rhythm monitoring were performed for all patients. Fasting venous blood samples were taken from all study patients to measure serum thiol-disulphide homeostasis, Hs-CRP and Hs-TnI. Results: Serum-native thiol was lower and disulphide/native thiol ratio was more oxidized in HCM patients with AF (p < 0.001). Also, HCM patients with AF had higher Hs-TnI and Hs-CRP than no-AF HCM patients. Disulphide/native thiol ratio, serum-native thiol, age, NYHA functional class≥III, and advanced diastolic dysfunction were independently associated with the presence of AF in HCM. Conclusion: In addition to clinical and echocardiographic findings, oxidative stress is also associated with AF in HCM patients.

Association Between Morning Surge in Systolic Blood Pressure and SYNTAX Score I in Patients With Stable Coronary Artery Disease.

A high morning surge in systolic blood pressure poses a risk in people who have cardiovascular disease. We investigated the relationship between this phenomenon and the SYNTAX score I in patients who had stable coronary artery disease. Our single-center study included 125 consecutive patients (109 men and 16 women; mean age, 54.3 ± 9 yr) in whom coronary angiography revealed stable coronary artery disease. We calculated each patient's sleep-trough morning surge in systolic blood pressure, then calculated the SYNTAX score I. The morning surge was significantly higher in patients whose score was >22 (mean, 22.7 ± 13.2) than in those whose score was ≤22 (mean, 12.4 ± 7.5) (P <0.001). Forward stepwise logistic regression analysis revealed that morning surge in systolic blood pressure was the only independent predictor of an intermediate-to-high score (odds ratio=1.183; 95% CI, 1.025-1.364; P=0.021). To our knowledge, this is the first study to show an association between morning surge in systolic blood pressure and the SYNTAX score I in patients who have stable coronary artery disease.

Prevalence and etiologies of pulmonary hypertension at Somalia-Turkey Training and Research Hospital in Mogadishu.

INTRODUCTION: pulmonary hypertension (PH) is one of the leading causes of mortality in the world. This study aimed to determine the ratio distribution and etiological characteristics of PH in Somalia-Turkey Training and Research Hospital. METHODS: the study was designed as a hospital-based retrospective observational study and included 260 patients who were diagnosed with PH by transthoracic echocardiography (TTE) in the cardiology outpatient clinic in Somalia-Turkey Training and Research Hospital in Mogadishu. Sociodemographic and clinical characteristics and data on morbidity were retrieved from clinical records. RESULTS: the echocardiographic prevalence of PH was found to be 18% (n=260). PH due to left heart disease was the most common form of PH (n=151, 58%), followed by PH due to lung disease (n=61, 23%), group 1 PH (n=38, 16%), group 5 PH (n=7, 2%), and chronic thromboembolic PH (CTEPH) (n=3, 1%). CONCLUSION: the present study showed that the prevalence of PH in Somalia is relatively higher than the rest of the world's average. The distribution characteristics of the disease could be related to the region-specific differences of the causative diseases. Further studies are needed to better capture the epidemiology of PH in Somalia.
