Clinical safety and effectiveness of the Genoss drug-eluting stent in real-world clinical practice

Background/Aims@#The Genoss DES™ is a novel, biodegradable, polymer-coated, sirolimus-eluting stent with a cobalt- chromium stent platform and thin strut. Although the safety and effectiveness of this stent have been previously investigated, real-world clinical outcomes data are lacking. Therefore, the aim of this prospective, multicenter trial was to evaluate the clinical safety and effectiveness of the Genoss DES™ in all-comer patients undergoing percutaneous coronary intervention. @*Methods@#The Genoss DES registry is a prospective, single-arm, observational trial for evaluation of clinical outcomes after Genoss DES™ implantation in all-comer patients undergoing percutaneous coronary intervention from 17 sites in South Korea. The primary endpoint was a device-oriented composite outcome of cardiac death, target vessel-related myocardial infarction (MI), and clinically driven target lesion revascularization (TLR) at 12 months. @*Results@#A total of 1,999 patients (66.4 ± 11.1 years of age; 72.8% male) were analyzed. At baseline, 62.8% and 36.7% of patients had hypertension and diabetes, respectively. The implanted stent number, diameter, and length per patient were 1.5 ± 0.8, 3.1 ± 0.5 mm, and 37.0 ± 25.0 mm, respectively. The primary endpoint occurred in 1.8% patients, with a cardiac death rate of 1.1%, target vessel-related MI rate of 0.2%, and clinically driven TLR rate of 0.8%. @*Conclusions@#In this real-world registry, the Genoss DES™ demonstrated excellent safety and effectiveness at 12 months among all-comer patients undergoing percutaneous coronary intervention. These findings suggest that the Genoss DES™ may be a viable treatment option for patients with coronary artery disease.

Disseminated Staphylococcus aureus infection and acute bacterial pericarditis: a case report / 고신대학교의과대학학술지

We experienced a case of disseminated Staphylococcus aureus infection with bacterial pericarditis that progressed to septic shock and multiorgan failure despite pericardiocentesis and surgical removal of the original abscess with intensive antibiotic therapy. We report this case because of the patient’s very rare and remarkable echocardiographic findings and highly turbid pericardial effusion.

Postoperative effects of bariatric surgery on heart rate recovery and heart rate variability / 고신대학교의과대학학술지

Background@#Several studies have reported associations between obesity and autonomic dysfunction. However, little research has investigated the effect of bariatric surgery on heart rate recovery (HRR) in the treadmill test and heart rate variability (HRV) in 24-hour Holter monitoring. We investigated the effects of bariatric surgery on HRR and HRV, which are parameters related to autonomic dysfunction. @*Methods@#We retrospectively investigated patients who underwent bariatric surgery in 2019. The treadmill test, 24-hour Holter monitoring, and echocardiography were performed before and 6 months after surgery. We compared the changes in HRR in the treadmill test and HRV parameters such as the time domain and spectral domain in 24-hour Holter monitoring before and after surgery. @*Results@#Of the 40 patients who underwent bariatric surgery, 25 patients had the treadmill test or 24-hour Holter monitoring both before and after surgery. Body weight and body mass index significantly decreased after surgery (112.86±24.37 kg vs. 89.10±20.26 kg, p<0.001; 39.22±5.69 kg/m2 vs. 31.00±5.09 kg/m2, p<0.001, respectively). HRR significantly increased (n=23; 43.00±20.97 vs. 64.29±18.49, p=0.001). The time domain of HRV parameters increased (n=21; standard deviation of the N-N interval 123.57±28.05 vs. 152.57±39.49, p=0.002 and mean N-N interval 791.57±88.84 vs. 869.05±126.31, p=0.002). @*Conclusions@#Our data showed that HRR after exercise and HRV during 24-hour Holter monitoring improved after weight reduction with bariatric surgery through improved cardiac autonomic function.

Effects of White-coat Hypertension on Heart Rate Recovery and Blood Pressure Response during Exercise Test / 고신대학교의과대학학술지

Objectives@#White-coat hypertension is defined as high blood pressure (BP) on clinical assessment but normal BP elsewhere or on ambulatory measurement. Autonomic dysfunction may be one of the mechanisms causing white-coat hypertension.Slowed heart rate recovery and excessive BP response during exercise test are associated with autonomic dysfunction.The purpose of this study was to determine the association between white-coat hypertension and abnormal autonomic nervous system response. @*Methods@#We assessed 295 patients stratified into three groups via 24hr ambulatory BP monitoring, following 2017 ACC/AHA guidelines : normal BP group, white-coat hypertension group, and a hypertension group. We analyzed medical history, blood test, echocardiography, 24hr ambulatory BP monitoring, and exercise test data. @*Results@#There was no difference in basement characteristics and echocardiography among the groups. Blunted heart rate recovery of each group showed a significant difference. Control group had 0% blunted heart rate recovery, but 33.3% in white coat group and 27.6% in true hypertension group (P < 0.001). Also, in the control group, 4.5% showed excessive BP response, but 31.5% in the white coat hypertension group and 29.3% in the true hypertension group (P < 0.001). Excessive BP response during the exercise test or blunted heart rate recovery, which is an indicator of autonomic nervous system abnormality, was more common in the hypertensive group and white-coat hypertension group than in the normal BP group. @*Conclusions@#These results confirmed that white-coat hypertension has an autonomic nervous system risk. Therefore, white-coat hypertension can be a future cardiovascular risk factor.

Bioresorbable Vascular Scaffold Korean Expert Panel Report

Bioresorbable vascular scaffold (BRS) is an innovative device that provides structural support and drug release to prevent early recoil or restenosis, and then degrades into nontoxic compounds to avoid late complications related with metallic drug-eluting stents (DESs). BRS has several putative advantages. However, recent randomized trials and registry studies raised clinical concerns about the safety and efficacy of first generation BRS. In addition, the general guidance for the optimal practice with BRS has not been suggested due to limited long-term clinical data in Korea. To address the safety and efficacy of BRS, we reviewed the clinical evidence of BRS implantation, and suggested the appropriate criteria for patient and lesion selection, scaffold implantation technique, and management.

The significance of blood pressure variation and metabolic risk factors in patients with different stages of hypertension / 고신대학교의과대학학술지

OBJECTIVES: Blood pressure variation (BPV) and metabolic syndrome is an independent risk factor for cardiovascular events. Ambulatory blood Pressure (ABP) has been shown to be more closely related to cardiovascular events in hypertensive patients than conventional office BP (OBP). Using both OBP and ABP, 4 groups of patients were identified: (1) normotensive patients (NT); (2) white coat hypertensives (WCHT); (3) masked hypertensives (MHT); and (4) sustainedhypertensives (SHT). We investigated the significance of BPV and metabolic risks of these 4 groups. METHODS: This study is a retrospective analysis of patients between January 2008 and May 2013. Echocardiography and 24 hour ABP monitoring were performed. RESULTS: BMI was significantly higher in the MHT compared with the NT. There were progressive increases in fasting glucose level from NT to WCHT, MHT, and SHT.MHT and SHT had higher 24h and nighttime BPV than NT.MHT was significantly related with BMI (r = 0.139, P = 0.010), creatinine (r = 0.144, P = 0.018), fasting glucose (r = 0.128, P = 0.046), daytime systolic BPV (r = 0.130, P = 0.017), and daytime diastolic BPV (r = 0.130, P = 0.017). Dyslipidemia (r = 0.110, P = 0.043), nighttime systolic BPV (r = 0.241, P < 0.001) and nighttime diastolic BPV (r = 0.143, P = 0.009) shown correlation with SHT. In multivariate logistic regression, MHT was independently associated with Body mass index (OR 1.086, 95% CI 1.005–1.174, P = 0.038) and creatinine (OR 1.005, 95% CI 1.001–1.010, P = 0.045). CONCLUSIONS: BPV and metabolic risk factors were found to be greater in MHT and SHT compared with NT and WCHT. This suggests that BPV and metabolic risks may contribute to the elevated cardiovascular risk observed in patients with MHT and SHT.

The Combined Impact of Neutrophil-to-Lymphocyte Ratio and Type 2 Diabetic Mellitus on Significant Coronary Artery Disease and Carotid Artery Atherosclerosis

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a new important inflammatory marker for predicting cardiovascular events. This study aimed to evaluate the combined impact of NLR and type 2 diabetes mellitus (T2DM) on significant coronary artery disease (CAD) and carotid artery atherosclerosis. METHODS: This study includes a total of 828 patients evaluated by coronary angiography and carotid ultrasonography. Significant CAD was defined as at least one vessel with stenosis greater than 50%. We employed logistic regression models to investigate the association of NLR and T2DM with significant CAD. The goodness-of-fit and discriminability of the models were assessed by the loglikelihood ratio test and C-index, respectively. Also, we investigated the clinical relevance of the categorized NLR that classifies patients into three risk groups (low, intermediate, high). RESULTS: According to logistic regression analysis, both NLR {adjusted odds ratio (OR) 1.31, p 2) showed the greater prevalence of significant CAD and carotid artery atherosclerosis compared with patients without T2DM or type 2 diabetic patients assigned into the low risk group (NLR ≤ 1). CONCLUSION: Our results suggest that type 2 diabetic patients with high inflammatory state would be more vulnerable to significant CAD and carotid artery atherosclerosis.

The Impact of Subclinical Hypothyroidism or Thyroid Autoimmunity on Coronary Vasospasm in Patients without Associated Cardiovascular Risk Factors

BACKGROUND AND OBJECTIVES: Subclinical hypothyroidism is associated with endothelial dysfunction and impaired coronary flow reserve. However, the effect of subclinical hypothyroidism or thyroid autoimmunity on variant angina has yet to be determined. SUBJECTS AND METHODS: Among 385 consecutive patients without associated cardiovascular risk factors who underwent coronary angiography with the ergonovine provocation test (EPT), 165 had a positive EPT {EPT(+)} and 220 had a negative EPT {EPT(-)}. The relationship between coronary artery spasm and the presence of subclinical thyroid dysfunction as well as serum thyroid peroxidase autoantibody (TPO Ab) was evaluated. RESULTS: The proportion of patients with subclinical hypothyroidism among those who were EPT(+) was significantly higher than that in those who were EPT(-) (18% vs. 11%, p=0.001). However, there was no significant difference in the proportion of patients with subclinical hyperthyroidism between the groups. Moreover, EPT(+) patients showed significantly more positive TPO Ab (33% vs. 14%, p<0.001) than those with EPT(-). There was a positive correlation between EPT(+) and TPO positivity (r=0.226, p<0.001), subclinical hypothyroidism (r=0.112, p=0.033), and body mass index (r=0.123, p=0.018). Binary logistic regression analysis revealed that the significant predictors of EPT(+) were body mass index {adjusted odds ratio (OR)=1.042, 95% confidence interval (CI)=1.005-1.080}, presence of subclinical hypothyroidism (OR=3.047, 95% CI=1.083-8.572), TPO Ab titer (OR=1.028, 95% CI=1.015-1.041), and the presence of TPO Ab (OR=4.904, 95% CI=1.544-15.567). CONCLUSION: Subclinical hypothyroidism and the presence of TPO Ab are significantly associated with coronary vasospasm in patients without cardiovascular risk factors.

A Case of Persistent Apical Ballooning Complicated by Apical Thrombus in Takotsubo Cardiomyopathy of Systemic Lupus Erythematosus Patient

Takotsubo cardiomyopathy, which is also known as "transient apical ballooning", is a cardiac syndrome associated with emotional and physical stress that occurs in postmenopausal women. It may mimic acute coronary syndrome but coronary angiography reveals normal epicardial coronary arteries. The prognosis is favorable with the normalization of wall motion abnormalities within weeks. We report a case of persistent apical ballooning complicated by an apical thrombus in Takotsubo cardiomyopathy of systemic lupus erythematous patient. Takotsubo cardiomyopathy may not be always transient and left ventricular thrombus can occur in the disease course as our patient.

Protective Effects of Houttuynia cordata Thunb. on Gentamicin-induced Oxidative Stress and Nephrotoxicity in Rats

Development of a therapy providing protection from, or reversing gentamicin-sulfate (GS)-induced oxidative stress and nephrotoxicity would be of great clinical significance. The present study was designed to investigate the protective effects of Houttuynia cordata Thunb. (HC) against gentamicin sulfate-induced renal damage in rats. Twenty-eight Sprague-Dawley rats were divided into 4 equal groups as follows: group 1, control; group 2, GS 100 mg/kg/d, intraperitoneal (i.p.) injection; group 3, GS 100 mg/kg/d, i.p. + HC 500 mg/kg/d, oral; and group 4, GS 100 mg/kg/d i.p. + HC 1000 mg/kg/d, oral administration). Treatments were administered once daily for 12 d. After 12 d, biochemical and histopathological analyses were conducted to evaluate oxidative stress and renal nephrotoxicity. Serum levels of creatinine, malondialdehyde (MDA), and blood urea nitrogen (BUN), together with renal levels of MDA, glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) were quantified to evaluate antioxidant activity. Animals treated with GS alone showed a significant increase in serum levels of creatinine, BUN, and MDA, with decreased renal levels of GSH, SOD, and CAT. Treatment of rats with HC showed significant improvement in renal function, presumably as a result of decreased biochemical indices and oxidative stress parameters associated with GS-induced nephrotoxicity. Histopathological examination of the rat kidneys confirmed these observations. Therefore, the novel natural antioxidant HC may protect against GS-induced nephrotoxicity and oxidative stress in rats.

Hypoadiponectinemia in Patients With Paroxysmal Atrial Fibrillation

BACKGROUND AND OBJECTIVES: Adiponectin is an adipose tissue-derived hormone that has beneficial effects on cardiac function and has been reported to be associated with lipid metabolism, glucose metabolism, and insulin resistance. Serum levels of adiponectin are reduced in obese individuals compared with non-obese individuals. Obesity is associated with an increased incidence of atrial fibrillation (AF); however, the role of adiponectin in AF is unclear. The aim of this study is to evaluate the relationship between the plasma adiponectin level and AF. SUBJECTS AND METHODS: Sixty-one consecutive patients were prospectively enrolled for this study. Subjects were divided into two groups: patients with AF (n=30) and controls (n=31). Laboratory evaluation, including levels of plasma adiponectin, was performed and echocardiographic parameters were measured. RESULTS: The baseline characteristics were not different between the two groups. The plasma adiponectin level of patients in the AF group was significantly lower than in the control group (14.9+/-7.2 vs. 19.+/-8.9 microg/mL, p<0.05). In addition, when we divided the AF patients into paroxysmal and chronic AF, the plasma adiponectin level was significantly lower in patients with paroxysmal AF, compared with the control group. In multiple binary logistic regression analysis to evaluate the independent predictors for AF, adiponectin and left atrial diameter were strong independent predictors of AF. CONCLUSION: In this study a lower plasma adiponectin concentration was significantly associated with that of paroxysmal AF. Hypoadiponectinemia can potentially be an important risk factor for AF.

Correlation of Right Atrial Appendage Velocity with Left Atrial Appendage Velocity and Brain Natriuretic Peptide

BACKGROUND: Left atrial appendage (LAA) anatomy and function have been well characterized both in healthy and diseased people, whereas relatively little attention has been focused on the right atrial appendage (RAA). We sought to evaluate RAA flow velocity and to compare these parameters with LAA indices and with a study of biomarkers, such as brain natriuretic peptide, among patients with sinus rhythm (SR) and atrial fibrillation (AF). METHODS: In a series of 79 consecutive patients referred for transesophageal echocardiography, 43 patients (23 with AF and 20 controls) were evaluated. RESULTS: AF was associated with a decrease in flow velocity for both LAA and RAA [LAA velocity-SR vs. AF: 61 +/- 22 vs. 29 +/- 18 m/sec (p < 0.01), RAA velocity-SR vs. AF: 46 +/- 20 vs. 19 +/- 8 m/sec (p < 0.01)]. Based on simple linear regression analysis, LAA velocity and RAA velocity were positively correlated, and RAA velocity was inversely correlated with brain natriuretic peptide (BNP). CONCLUSION: AF was associated with decreased RAA and LAA flow velocities. RAA velocity was found to be positively correlated with LAA velocity and negatively correlated with BNP. The plasma BNP concentration may serve as a determinant of LAA and RAA functions.

Prognosis and Natural History of Drug-Related Bradycardia

BACKGROUND AND OBJECTIVES: The prognosis and natural history of bradycardia related to drugs such as beta-blockers and non-dihydropyridine calcium channel blockers are not well known. SUBJECTS AND METHODS: We retrospectively analyzed 38 consecutive patients (age 69+/-11, 21 women) with drug-related bradycardia (DRB) between March 2005 and September 2007. A drug-associated etiology for the bradycardia was established based on the medical history and patient response to drug discontinuation. The mean follow-up duration was 18+/-8 months. RESULTS: The initial electrocardiogram (ECG) showed sinus bradycardia (heart rate < or =40/min) in 13 patients, sinus bradycardia with junctional escape beats in 18 patients, and third-degree atrioventricular (AV) block in seven patients. Drug discontinuation was followed by resolution of bradycardia in 60% of patients (n=23). Among them, five (17.8%) patients resumed taking the culprit medication after discharge and none developed bradycardia again. Bradycardia persisted in 10 (26.3%) patients despite drug withdrawal, and a permanent pacemaker was implanted in seven of them. Third-degree AV block, QRS width, and bradycardia requiring temporary transvenous pacing were significantly associated with the bradycardia caused by drugs. CONCLUSION: Beta-blockers were the most common drugs associated with DRB. However, in one quarter of the cases the DRB was not associated with drugs; in these patients permanent pacemaker implantation should be considered.

Gender Differences of P Wave Signal Averaged Electrocardiograms: Based on the Risk of Atrial Fibrillation

BACKGROUND AND OBJECTIVES: Certain types of arrhythmias have gender differences. Women have a higher incidence of drug-induced QT prolongation than in men. However, there are no reports regarding gender-related differences of the P wave signal averaged electrocardiogram (PWSAE), based on the risk of atrial fibrillation (AF). PWSAE has been recognized as a diagnostic tool for identifying the risk of paroxysmal atrial fibrillation (PAF). We therefore investigated the influence of gender in the parameters of PWSAE and in the risk of AF. SUBJECTS AND METHODS: We recorded 100 PWSAEs in apparently healthy Korean subjects (53 men and 47 women), aged 20 to 79 years. RESULTS: The mean age of the male subjects was 38.2 years and the mean age of the female subjects was 43.2 years (p=0.19). The body surface area (BSA) were larger in men (1.83 m2 vs. 1.53 m2, p<0.05). In men, the filtered P wave duration (fPD) was longer than in women (136.8 msec vs. 125.2 msec, p<0.05). The root mean square voltage in the terminal 20 ms of the filtered P wave (RMS20) was 5.9 micron V in women and 4.5 micron V in men (p<0.05). CONCLUSION: Men have a longer fPD and lower RMS20 than women. The BSA showed a positive correlation with fPD and a negative correlation with RMS20. This study suggests that BSA is an important factor for fPD and RMS20. In addition, as men have a larger BSA as compared with women, we suspect that men have a higher risk of AF as compared with women.

Aneurysmal Rupture of the Anterior Leaflet of the Mitral Valve Secondary to Bicuspid Aortic Valve Endocarditis

Aneurysm formation and rupture of the anterior mitral leaflet is a rare complication of infectious aortic valve endocarditis. Prompt diagnosis and early surgical treatment can prevent complications such as embolization and cardiogenic shock. It is also related to the acute and severe mitral regurgitation. We describe a case of aneurysm of the anterior mitral leaflet secondary to bicuspid aortic valve endocarditis.
