Abstract PDF: Due to the high prevalence of hypertension, hypertensive patients undergo perioperative evaluation and management. Severe hypertension may increase the operative risk. However, hypertension with a diastolic blood pressure of less than 110 mmHg usually does not appear to increase the risk. In general, it is recommended that oral antihypertensive drugs be continued before and after surgery. In particular, sympathetic blockers, such as beta-blockers, should be maintained. It is generally recommended to continue intake of calcium channel blockers, especially for surgeries with a low bleeding risk. However, in the case of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, it is recommended that they be stopped 24 hours before surgery because they can inhibit excessive compensatory renin-angiotensin activation during surgery. Statin and aspirin medications are often prescribed for patients with hypertension. It is recommended to continue intake of statins in the perioperative period. Aspirins are recommended for low-risk patients undergoing noncardiac surgery.

Statins are one of the most widely used drugs worldwide as first-line drugs for the treatment of hyperlipidemia and the prevention and treatment of cardiovascular diseases. Most of the side effects of statins are known to be mild, and mainly hepatotoxicity and various muscle symptoms are known. Recently, there have been studies on concerns about an increase in the incidence of diabetes after using statins, but it was found that the benefits sufficiently outweigh the risk of side effects. Therefore, the use of statins in the appropriate group should be actively performed, and it seems that the side effects can be prevented through close physical observation and appropriate examination.

Abstract PDF: Diabetes mellitus and cancer are the most common life-threatening illnesses worldwide. Previous epidemiological studies have suggested a strong association between diabetes mellitus and an increased risk of cancer. Potential biological mechanisms underlying this relationship include obesity, hyperglycemia, hyperinsulinemia, chronic inflammation, and oxidative stress. The most common diabetes-related cancers are pancreatic, hepatocellular, breast, endometrial, and colorectal cancer. Special attention should be paid to patients with diabetes through careful cancer screening and preventive anticancer strategies.

Antiplatelet Therapy for Secondary Stroke Prevention in Patients with Ischemic Stroke or Transient Ischemic Attack: Kyung-Yul Lee; Cardiovasc Prev Pharmacother. 2021;3(4):86-94. Published online October 31, 2021; DOI: https://doi.org/10.36011/cpp.2021.3.e10

Abstract PDF: The risk of stroke recurrence is highest in the acute phase after transient ischemic attack (TIA) or ischemic stroke. Therefore, patients with TIA or ischemic stroke should be treated with antiplatelet medication for stroke prevention. The short-term use of dual antiplatelet therapy between 21 and 90 days may be considered in those with acute minor stroke or TIA and highrisk of recurrence. However, the long-term use of dual antiplatelet therapy is not recommended due to the risk of bleeding. The current stroke guideline does not specify the administration of an antiplatelet for the secondary prevention of ischemic stroke. However, as clinical studies progress, antiplatelet therapy may become a personalized treatment in the future.

Abstract PDF

Hypertension is a major cause of maternal morbidity and occurs as a complication in up to one in ten pregnancies. Hypertensive disorders of pregnancy encompass gestational hypertension, preeclampsia, chronic hypertension, and chronic hypertension with superimposed preeclampsia. However, the management of hypertensive disorders of pregnancy remains a matter of debate, particularly the blood pressure thresholds and targets for managing hypertension in pregnancy. Previously, there was no clear evidence of the effectiveness of aggressive blood pressure control in pregnancy due to the risk of fetal growth restriction. Recent clinical trials have shown that aggressive control of blood pressure in pregnant women is safe for both the mother and fetus. The purpose of this paper is to present a clinically oriented guide to the drugs of choice in patients with hypertension during pregnancy, present contrasts among different guidelines and recent clinical trials, and discuss the blood pressure thresholds and targets for hypertension during pregnancy based on recent studies.

Abstract PDF

Transthyretin amyloid (ATTR) cardiomyopathy is a progressive disease caused by the infiltration of ATTR fibrils in the myocardium. Although it is a rare disease, ATTR cardiomyopathy is an important cause of heart failure with preserved ejection fraction, and its incidence is increasing due to improved diagnostic imaging tools. There has been a breakthrough in the field of transthyretin amyloidosis, which opens a new therapeutic door for the patients. In this review, an overview of tafamidis therapy in ATTR cardiomyopathy with recent results from clinical trials will be discussed.

Abstract PDF

Cardiovascular disease (CVD) is the most frequently diagnosed disease as well as the leading cause of death in the elderly. It usually results from long-term effects of cardiovascular risk factors as well as the aging process itself. Elderly people commonly have geriatric syndrome, which is an age-specific problem that is complicated by the presence of cardiovascular, cognitive, and physical dysfunction and is accompanied by many other chronic diseases. While caring for the elderly, in addition to CVD, various inherent problems must be considered. The patient-centered approach, instead of evidence-based guidelines that are designed for young adult patients, is the most important concept when it comes to elderly patients with CVD and multiple comorbidities. This approach should be used to maintain the functionality, independence, quality of life, and dignity of these patients.

Adverse reactions to antiarrhythmic drugs: Ungjeong Do; Cardiovasc Prev Pharmacother. 2023;5(1):1-14. Published online January 16, 2023; DOI: https://doi.org/10.36011/cpp.2023.5.e1

Abstract PDF: There are various types of adverse reactions to antiarrhythmic drugs (AADs). Proarrhythmia, which refers to an exacerbation of the preexisting arrhythmia or occurrence of a new arrhythmia, may occur under the therapeutic concentration of an AAD. Bradyarrhythmia is the most common type of proarrhythmia due to AADs, and prior myocardial infarction and old age are known risk factors. Atrial flutter with 1:1 atrioventricular conduction usually occurs during rhythm control of atrial fibrillation with class IC AADs. QT prolongation due to AADs, mainly class III AADs, elevates the risk of torsade de pointes by triggered activity due to early afterdepolarization. The addition of clinical factors that promote QT prolongation, such as hypokalemia, hypomagnesemia, female sex, and bradycardia, increases the risk of developing torsade de pointes. Proarrhythmic monomorphic ventricular tachycardia usually occurs as a result of slow conduction and disparity of refractoriness due to class IC AADs. In patients with preexisting left ventricular systolic dysfunction or structural heart disease, the risk of hypotension or cardiogenic shock caused by negative inotropic effects due to AADs should be considered. To prevent these major adverse reactions to AADs, we need to understand the electrophysiologic properties of AADs in detail. Furthermore, the risk of proarrhythmia could be heightened by interplay with clinical factors, such as electrolyte unbalances, heart rate, and hepatic/renal or myocardial dysfunction. Sufficient awareness about drug-drug interactions, which may affect the metabolism of AADs, will improve patient safety during the management of arrhythmia.

Optimal target blood pressure in older patients with hypertension: Kwang-il Kim; Cardiovasc Prev Pharmacother. 2023;5(2):41-48. Published online April 24, 2023; DOI: https://doi.org/10.36011/cpp.2023.5.e4

Abstract PDF: Hypertension is a common condition among older adults, and blood pressure (BP) control is effective for preventing cardiovascular morbidity and mortality even among the oldest-old adults. However, the optimal target BP for older patients with hypertension has been a subject of debate, with previous clinical trials providing conflicting evidence. Determining the optimal target BP for older adults is a complex issue that requires considering comorbidities, frailty, quality of life, and goals of care. As such, BP targets should be individualized based on each patient's unique health status and risk factors, and treatment should be closely monitored to ensure that it is effective and well-tolerated. The benefits and risks of intensive BP control should be carefully weighed in the context of the patient's overall health status and treatment goals. Ultimately, the decision to pursue intensive BP control should be made through shared decision-making between patients and their healthcare providers.

Abstract PDF

Obesity is an independent risk factor for the development and progression of cardiovascular disease (CVD). Various cardiovascular outcomes are related to the association between body weight change and CVD. Metabolically healthy obese individuals could have a better prognosis in terms of cardiovascular morbidity and mortality than metabolically unhealthy obese individuals. Smoking cessation causes significant weight gain and consequent deterioration of the metabolic profile despite not impairing the cardiovascular benefits. Intentional weight loss has a consistent cardiovascular protective effect, but unintentional weight loss due to progressive catabolism and loss of muscle mass could be associated with poor cardiovascular outcomes. Obese individuals who are successful in losing weight with subsequent regain (weight cycling) could have an unfavorable cardiometabolic profile and the risk of CVD. Further studies are needed to evaluate the impact of weight changes on CVD by identifying unknown pathophysiology and to decide appropriate management and interventions for various phenotypes of weight change.

Abstract PDF: Background
Aspirin is known to aggravate coronary artery spasm (CAS) regardless of the dose (100–325 mg/day). However, it is unclear whether low-dose aspirin (LDA; 100 mg) has deleterious impacts on the clinical course of CAS patients in the long-term. Thus, we investigated the impact of LDA on the long-term clinical outcomes of CAS patients.
Methods
A total of 5,697 consecutive patients without significant coronary artery disease who underwent an acetylcholine provocation test from November 2004 to May 2015 were enrolled. Of these patients, 3,072 CAS patients were enrolled in the study and divided into two groups based on whether they took LDA: the LDA group (n=338) and the non-LDA group (n=2,734). All CAS patients were prescribed anti-anginal medication as appropriate. To adjust for any potential confounders that could cause bias, a propensity score matching analysis was performed using a logistic regression model.
Results
After propensity score matching, two propensity-matched groups (524 pairs, 1,048 patients, C-statistic=0.827) were generated, and the baseline characteristics of the two groups were balanced. The two groups were showed no significant differences in any follow-up events, such as major adverse cardiac events and recurrent angina.
Conclusions
The main finding of the present study is that the use of LDA did not affect cardiovascular events up to 5 years in CAS patients. Therefore, the prescription of LDA in these patients should be individualized considering their clinical status.

Abstract PDF: The accuracy of a diagnostic test should be evaluated before it is used in clinical situations. The sensitivity, specificity, and the trade-off between the 2 need to be considered. Sensitivity and specificity in diagnostic tests depend on the selection of cut-off values, and appropriate cut-off values can be arrived at by analyzing the receiver operating characteristic curve. In actual clinical setting, it is often difficult to obtain an appropriate gold standard for diagnosis, and in this case, consent is required as well. In this article, we summarize the basic concepts and methods for evaluating the performance of diagnostic tests.

Abstract PDF: Background
The relationship between metformin intake and prostate cancer incidence remains unclear. Therefore, we examined the correlation between prostate cancer and metformin use.
Methods
The subjects were diabetes patients aged ≥50 years who had been diagnosed with prostate cancer and had undergone surgery at Seoul St. Mary's Hospital. Groups taking metformin (MET(+) group) and not taking metformin (MET(–) group) were divided and compared.
Results
The mean preoperative prostate-specific antigen (PSA) levels in the MET(–) and MET(+) groups were 10.7±11.9 and 8.0±5.6 ng/mL, respectively, with no statistically significant difference between the two groups (P=0.387). The average prostate volume of the MET(–) group was 82.4±98.0 mL, and the average prostate volume of the MET(+) group was 55.4±20.1 mL, but there was no statistically significant difference between the two groups (P=0.226). The mean PSA velocity also did not show a significant difference between the two groups (0.025±0.102 ng/mL vs. 0.005±0.012 ng/mL, P=0.221).
Conclusions
We did not identify a significant positive correlation between metformin and prostate cancer. However, preoperational PSA and PSA velocity tended to be lower in the MET(+) group. A sophisticated prospective study with a large sample size should be planned.

Relationship between serum ferritin levels during iron chelating therapy and diastolic left ventricular function in transfusion-induced iron overload: a 2-year follow-up study in patients with aplastic anemia: Woo-Baek Chung; Cardiovasc Prev Pharmacother. 2023;5(3):81-90.

Abstract PDF: Background
The goal of the study was to investigate changes in cardiac function during iron chelating therapy (ICT) in patients with transfusion-induced iron overload.
Methods
We prospectively examined cardiac function in 21 aplastic anemia patients for 2 years by using transthoracic echocardiography before and during ICT.
Results
The serum ferritin level decreased from 4,961.5±2,917.9 µg/L to 2,466.9±2,533.1 µg/L after 2 years (P<0.001). The left ventricular ejection fraction decreased to under the normal limit (55%) in five patients. The serum ferritin level was positively correlated with the E/E’ ratio (r=0.595, P=0.004) and the left atrial (LA) volume (r=0.685, P=0.001) and negatively correlated with the deceleration time (r=–0.586, P=0.005) after 2 years of ICT. The seven responders (serum ferritin level <1,000 µg/L after 2 years of ICT) demonstrated a significantly higher ejection fraction, smaller LA volume and left ventricular end-systolic dimension, and a slower deceleration time than the 14 nonresponders (≥1,000 µg/L).
Conclusions
These results suggest that the response to ICT, which was estimated by the serum ferritin level, can reflect cardiac function during ICT. In nonresponders, cardiac function monitoring during ICT may be helpful for the early detection of cardiac dysfunction.

Background
Liraglutide, a drug used for the management of obesity, has many known side effects. In this study, we developed a predictive model for the occurrence of liraglutide-related side effects using data from electronic medical records (EMRs).
Methods
This study included 237 patients from Seoul St. Mary's Hospital and Eunpyeong St. Mary's Hospital who were prescribed liraglutide. An endocrinologist obtained medical data through an EMR chart review. Model performance was evaluated using the mean of the area under the receiver operating characteristic curve (AUROC) with a 95% confidence interval (CI).
Results
A predictive model was developed for patients who were prescribed liraglutide. However, 37.1% to 75.5% of many variables were missing, and the AUROC of the developed predictive model was 0.630 (95% CI, 0.551–0.708). Patients who had previously taken antiobesity medication had significantly fewer side effects than those without previous antiobesity medication use (20.7% vs. 41.4%, P<0.003). The risk of side effect occurrence was significantly higher in patients with diabetes than in patients without diabetes by 2.389 times (odds ratio, 2.389; 95% CI, 1.115–5.174).
Conclusions
This study did not successfully develop a predictive model for liraglutide-related side effects, primarily due to issues related to missing data. When prescribing antiobesity drugs, detailed records and basic blood tests are expected to be essential. Further large-scale studies on liraglutide-related side effects are needed after obtaining high-quality data.
