AI Article Synopsis
- Hypertension is a complex condition leading to serious complications like stroke and myocardial infarction, and various medications, including amlodipine, are commonly used to manage it.
- A systematic review evaluated studies published from 2000 to August 2020 to investigate the effectiveness of amlodipine on reducing instances of stroke and myocardial infarction in hypertensive patients.
- The results indicated that amlodipine significantly lowers the risk of stroke and MI in these patients, supporting its role in hypertension management.
Article Abstract
Introduction: Hypertension is a progressive cardiovascular condition arising from complex aetiologies. Progression is strongly associated with functional and structural abnormalities that lead to multi-organ dysfunction. Stroke and myocardial infarction are two of the major complications of hypertension in India. Various anti-hypertensive drugs, such as calcium channel blockers (CCBs), beta-blockers, diuretics, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, have been the medications of choice for disease management and are known to be effective in reducing the complications of hypertension. CCBs, such as amlodipine, are also currently being used and proven to be effective, although their beneficial effects in the management of complications of hypertension like stroke and myocardial infarction (MI) have yet to be proven. Therefore, the aim of this systematic review was to evaluate the effect of amlodipine on stroke and MI in hypertensive patients.
Methods: A systematic search of English electronic databases was performed for studies with sufficient statistical power that were published between 2000 andl 30 August 2020, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. A total of 676 papers were screened, and 13 were found eligible to be included in the meta-analysis. Studies that included patients who suffered from MI or stroke and were under amlodipine treatment were included in the analysis. The odds ratio and the risk ratio of amlodipine compared to active control/placebo were noted from the studies and statistically analyzed.
Results: Amlodipine had a significant effect in reducing stroke and MI in hypertensive patients. Similar to results published in reports, this systematic review proved that the hazard ratio for amlodipine was < 1 for stroke (0.69-1.04) and MI (0.77-0.98), showing that amlodipine accounted for better prevention of stroke and MI.
Conclusion: In the pooled analysis of data from 12 randomised controlled trials and one double-blinded cohort study measuring the effect of CCBs, we found that the CCB amlodipine reduced the risk of stroke and MI in hypertensive patients. Superior results for amlodipine were found in ten of the 13 studies included in this meta-analysis.

Introduction: Dl-3-n-butylphthalide (NBP), a small molecular compound extracted from celery seeds, has been shown to exhibit diverse pharmacological activities, including anti-inflammatory, antioxidative, and anti-apoptotic effects. Recent studies have highlighted its efficacy in treating various cardiovascular conditions, such as myocardial infarction, hypertrophy, heart failure, and cardiotoxicity. This study aimed to investigate whether NBP could alleviate cardiac dysfunction and injury following hemorrhage-induced cardiac arrest (HCA) in a porcine model and elucidate its potential mechanisms.

Background: Atrial fibrillation (AF) is common in COVID-19 patients. The impact of AF on major-adverse-cardiovascular-events (MACE defined as all-cause mortality, myocardial infarction, ischemic stroke, cardiac failure or coronary revascularisation), recurrent AF admission and venous thromboembolism in hospitalised COVID-19 patients is unclear.
Methods: Patients admitted with COVID-19 (1-January-2020 to 30-September-2021) were identified from the New South Wales Admitted-Patient-Data-Collection database, stratified by AF status (no-AF vs prior-AF or new-AF during index COVID-19 admission) and followed-up until 31-Mar-2022.

Background: Stroke is a significant cause of morbidity and mortality worldwide, contributing substantially to the global burden of disease. In low- and middle-income countries, stroke tends to occur at younger ages, with infection being one of the notable contributing factors. Previous studies have explored the impact of nontyphoidal Salmonella (NTS) on vascular and blood-related diseases, with animal experiments confirming related mechanisms.

Background: Amyloidosis is a multi-organ disease of emerging significance in the field of cardiology. Chylothorax, a specific form of pleural effusion characterized by lymphatic fluid accumulation in the pleural cavity, is an extremely rare manifestation of amyloidosis. Notably, only five cases of chylothorax related to cardiac amyloidosis have been reported worldwide, all in amyloid light chain (AL) amyloidosis.

Background: To explore the mechanisms linking smoking to cardiovascular diseases (CVDs) from an epigenetic perspective.
Methods: Mendelian Randomization (MR) analysis was performed to assess the causal effects of smoking behavior and DNA methylation levels at smoking-related CpG sites on nine CVDs, including aortic aneurysm, atrial fibrillation, coronary atherosclerosis, coronary heart disease, heart failure, intracerebral hemorrhage, ischemic stroke, myocardial infarction, subarachnoid hemorrhage. Colocalization analysis was used to further identify key smoking-related CpG sites from the MR causal estimates.
