We conducted a study titled for Investigation on the characteristics of 24-hour blood pressure (BP) dipping patterns in hypertensive stroke patients. Methods: Descriptive research, analysis, and comparison, the research was conducted from July 2019 to September 2020 at the Vietnam Heart Institute - Bach Mai Hospital. There are 100 patients diagnosed with idiopathic hypertension who were divided into two groups (without stroke complications and another group with chronic stroke complications > 6 weeks), both groups were similar in age (45– 64 years old). Results: The daytime systolic BP (SBP) indices, 24-hour BP including SBP, diastolic BP (DBP), and mean arterial pressure (MAP), and particularly night-time BP indices were elevated in the stroke group compared with those without stroke complications (p < 0.05); there were no significant differences observed in daytime DBP and MAP between the two groups. SBP indices were higher in those with hemorrhage stroke compared with those with ischemic stroke, albeit without statistical significance. The prevalence of non-dipper was significantly higher in the stroke group compared with the non-stroke group (p < 0.001). Conclusion: The daytime SBP indices, 24-hour BP (SBP, DBP, MAP), and particularly night-time BP indices were elevated in the stroke group compared with those without stroke complications. The prevalence of non-dipper was significantly higher in the stroke group compared with the non-stroke group. [ABSTRACT FROM AUTHOR]

Study on the role of electrocardiographic (ECG) exercise testing for the possibility of permanent pacemaker implantation (PPI) in patients with sinus bradycardia (SB). Methods: Cross-sectional descriptive, prospective study. The study on 60 patients with SB below 50 beats/minute on 12-lead electrocardiogram at rest, with or without symptoms of SB, conducted at the Vietnam National Heart Institute and Hanoi Heart Hospital from January 2020 to September 2021. Results: Sixty patients with SB were studied, 36 male (60%) and 24 female patients (40%), p > 0.05. The average age was 55.12 ± 13.89 years old. Maximum exercise capacity (MEC) is low and only reaches 7.78 ± 3.59 metabolic equivalents (METs); Not reaching 85% of predicted MEC accounts for 53.5%; Maximum exercise time is 10.53 ± 0.46 minutes; Impaired heart rate (HR) variability in patients with SB is high: Chronotropic Index < 0.8 accounts for 53.5%, not reaching 85% of predicted HR max accounts for 45%. The average HR max was 129.90 ± 29.22 beats per minute (BPM). The average maximum workload systolic blood pressure was 155.23 ± 20.59 mmHg. The average value of maximum exercise diastolic blood pressure was 88.10 ± 9.11 mmHg. The HR decreased by 27.87 ± 16.82 BPM in the first minute. Not achieving 85% of predicted MEC (p = 0.062), so it is not an independent factor predicting the ability for PPI. Only the HR variability index < 0.8 is an independent predictor for PPI in bradycardic patients, which has OR = 21.521 (95% CI: 2.27– 04.34, p < 0.05). Conclusion: Results can be seen that Chronotropic Index < 0.8 is an important marker for physicians to decide on PPI in ECG during exercise testing in SB patients and is a potential prognostic factor for the need for PPI.

Study on effect of risk factors on over-anticoagulation in patients taking anticoagulant drugs with VKAs (vitamin K antagonists).Methods: Cross-sectional descriptive, prospective research. Study on 79 patients taking anticoagulant drugs with VKAs who had an INR (International Normalized Ratio) index of more than indicated anticoagulation dose with VKAs therapy.Results: A total of 79 patients, mean age 65.65 ± 12.17 years [33:85], the elderly group is common (73.4%). Patients had hemorrhage disorders account for 22.8%. The INR index had an average value was 5.88 ± 3.0 [3.02– 23.95]; The INR> 5 level group is a higher risk of bleeding than the INR ≤ 5 level group, it's the statistical significance (p < 0.001). The risk factors such as drugs to treat dyslipidemia, hyperthyroid, amiodarone, beta blocker, prednisone, NSAIDs (Non-steroidal anti-inflammatory), BMI (Body Mass Index), smoke and alcohol that the risk factors of increasing of bleeding when receiving anticoagulants but it's not statistically significant yet (OR > 1, p > 0.05); These patients using coenzyme Q10 and green vegetable nutrition such as cruciferous vegetables (Brassicaceae, Asteraceae) are quite common (31.6% and 35.4%), its effect on coagulation with vitamin K and cause of the increased in risk of bleeding was statistical significantly with OR = 5.28 (CI: 1.72– 16.17, p < 0.01), and OR = 2.99 (CI: 1.01– 8.80, p < 0.05) respectively.Conclusion: Most patients in over-anticoagulation were the elderly group. Patients had hemorrhage disorders account for 22.8%. The INR> 5 level group was a higher risk of bleeding than the INR ≤ 5 level group with statistical significance. Patients using Coenzyme Q10 and green vegetable nutrition such as cruciferous vegetables (Brassicaceae, Asteraceae) are quite common, its effect on coagulation and cause of the increased risk of bleeding complication with statistical significance.

Introduction: The permanent pacemaker implantation has a history of more than 60 years with improved mortality and quality of life but also recorded many complications., Objectives: The objective is to evaluate the rate of early complications at the National Heart Institute of Vietnam and the factors associated with the early complication of the permanent pacemaker implantation procedure., Methods: A cross-sectional descriptive is about 294 patients who received permanent pacemaker implantation at the National Heart Institute of Vietnam from 01/08/2020 to 30/30/2020., Results: The rate of complications is statistically higher in the diabetic group (OR = 2.5; 95% CI: 1.1-5.6), chronic kidney failure (OR = 2.7; 95% CI: 1.1-6.6), preheart surgery (OR = 3.8; 95% CI: 1.3-11.8), taking oral anticoagulants (OR = 4.3; 95% CI: 1.9-9.9), dual antiplatelets (OR = 2.95; 95% CI: 1.1-8.1), continuation to maintain anticoagulants, or dual antiplatelets (OR = 2.7; 95% CI: 1.2-6.4)., Conclusion: Early onset of complications (onset of early complications) has been associated with some factors such as diabetes disease, chronic kidney failure, preheart surgery, oral anticoagulants, dual antiplatelets, continuation to maintain anticoagulation, and antiplatelets with statistical significance., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Pharmacy and Bioallied Sciences.)
