Am J Cardiol 2024; 211:326-333. [PMID: 37993040 DOI: 10.1016/j.amjcard.2023.11.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 10/24/2023] [Accepted: 11/14/2023] [Indexed: 11/24/2023]
Abstract
This study aimed to compare the trends in cardiovascular diseases (CVDs)-related mortality in patients with Alzheimer's disease (AD) and in the general population aged ≥65 years. Data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research Multiple Cause of Death dataset were used to determine national trends in age-adjusted CVD mortality rates (AAMR) and average annual percent change (AAPC) values in patients with AD and the overall population aged ≥65 years from 1999 to 2020. Data for AAMR and AAPCs were also stratified by age, gender, ethnicity/race, geographical region, urbanization status, and subgroups of CVD. Trends in the overall AAMR stratified by gender, age, ethnicity/race, geographical region, urbanization status, and CVD subgroups were statistically different between patients with AD and the overall population (overall AAPC for CVD mortality rate in patients with AD = -3.5% [confidence interval -4.1% to -2.9%] vs -2.6% [confidence interval -2.3% to -2.9%] in overall population, p = 0.01). Differences in the decrease in the mortality rates between patients with AD and the overall population were found to be statistically different across all stratifications except for the change in the mortality rates for hypertensive diseases (p = 0.05), females (p = 0.2), and Asian or Pacific Islanders (p = 0.09). In conclusion, CVD-related mortality in patients with AD decreased over the last 2 decades, and decreases were more prominent than seen in the general population aged ≥65 years. These results may help focus public health efforts to optimize CVD health in patients with AD.

Abstract
Vortex formation during left ventricular diastolic filling may provide clinically useful insights into cardiac health. In recent years, there has been growing interest in the measurement of vortex formation time (VFT), especially because it is derived noninvasively. There are important applications of VFT in valvular heart disease, athletic physiology, heart failure and hypertrophic cardiomyopathy. The formation of the vortex as fluid propagates into the left ventricle from the left atrium is important for efficient fluid transport. Quantifying VFT may thus help in evaluating and understanding disease and pathophysiological processes.

Abstract
Cardiometabolic disorders (CMD) is a constellation of metabolic predisposing factors for atherosclerosis such as insulin resistance (IR) or diabetes mellitus (DM), systemic hypertension, central obesity, and dyslipidemia. Cardiometabolic diseases (CMDs) continue to be the leading cause of mortality in both developed and developing nations, accounting for over 32% of all fatalities globally each year. Furthermore, dyslipidemia, angina, arrhythmia, heart failure, myocardial infarction (MI), and diabetes mellitus are the major causes of death, accounting for an estimated 19 million deaths in 2012. CVDs will kill more than 23 million individuals each year by 2030. Nonetheless, new drug development (NDD) in CMDs has been increasingly difficult in recent decades due to increased costs and a lower success rate. Drug repositioning in CMDs looks promising in this scenario for launching current medicines for new therapeutic indications. Repositioning is an ancient method that dates back to the 1960s and is mostly based on coincidental findings during medication trials. One significant advantage of repositioning is that the drug's safety profile is well known, lowering the odds of failure owing to undesirable toxic effects. Furthermore, repositioning takes less time and money than NDD. Given these facts, pharmaceutical corporations are becoming more interested in medication repositioning. In this follow-up, we discussed the notion of repositioning and provided some examples of repositioned medications in cardiometabolic disorders.

Abstract
OBJECTIVE To evaluate the association between the use of cholinesterase inhibitors (ChEIs) and incident cardiovascular events (CVEs) among older patients with Alzheimer disease (AD). PATIENTS AND METHODS This retrospective cohort study was conducted with a new-user design and active-comparator design. The data source was the 2005-2014 Full Population file from the Health and Welfare Database in Taiwan. Patients were included if they were aged 50 years or older and had been diagnosed with AD between January 1, 2006, and December 31, 2010. The association between ChEI use and the risk of CVEs was investigated in patients with AD. Among the ChEI users, the risk of CVEs was further compared between patients with different cumulative doses and different ChEI treatment strategies. The propensity score method, which included matching and inverse probability of treatment weighting, was used to balance the potential confounders. A Cox proportional hazards model with competing risks was used to estimate the hazard ratio of CVEs. RESULTS The study included 6070 patients with AD. After covariate adjustment, ChEI users had a significantly lower risk of CVEs than nonusers (hazard ratio, 0.57; 95% CI, 0.51 to 0.62). Among ChEI users, patients with a high cumulative dose had a significantly lower risk of CVEs than those with a low cumulative dose (hazard ratio, 0.82; 95% CI, 0.70 to 0.96). CONCLUSION The use of ChEIs was associated with a decreased risk of incident CVEs among patients with AD. The cardioprotective effect of ChEIs showed a dose-response relationship.

Abstract
Background: Physicochemical properties play important role in fundamental issues like absorption and distribution of pharmaceuticals to the target tissue. This is particularly importantfor drugs acting in central nervous system (CNS). In this study, physicochemical properties of previously synthesized thiazole-pyridinium derivatives with anti-acetylcholinesterase activity and possible anti-Alzheimer effect were studied. Methods: Partition coefficient (n-octanol/water) and chromatographic Rf values for the studied compounds were determined using shake flask and high performance thin layer chromatography(HPTLC) methods, respectively. Different druglikeness properties of the compounds were also calculated using available software and web-servers. Results: The experimentally determined logarithm of partition coefficients (log P) for the studied compounds were in the range of -1.00 to -0.38. The Rf values for the studied compounds under the applied chromatographic condition ranged between 0.38 to 0.58. Moreover, calculated physicochemical properties, and druglikeness scores of the studied thiazole-pyridiniumderivatives and matching piperidine analogues were predicted. Furthermore, some ADMETfeatures of studied compounds like toxicity and metabolism by CYP450 (2C9, 2D6, 3A4, 1A2and 2C19) enzymes were predicted. Conclusion: The ranges of experimental and calculated LogP values for the studied thiazolepyridinumswere close. However, the determined Rf values showed relatively better correlation to the predicted LogP values indicating the suitability of used chromatographic method for comparing the lipophilicity of the positively charged pyridinium derivatives. The studied compounds were predicted to pass GI membrane and reach the CNS where they can exert their effects. In silico studies indicate that the piperidine counterparts of the studied thiazolepyridiniumsmay represent anti-Alzheimer agents with improved druglikeness properties.

Abstract
Elderly patients with Alzheimer's disease (AD) and other dementias are at high risk of polypharmacy and excessive polypharmacy for common coexisting medical conditions. Polypharmacy increases the risk of drug-drug and drug-disease interactions in these patients who may not be able to communicate early symptoms of adverse drug events. Three acetylcholinesterase inhibitors (ACHEIs) have been approved for AD: donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne). They are also used off-label for other causes of dementia such as Lewy body and vascular dementia. We here report evidence from the literature that ACHEI treatment, prescribed for cognitive impairment, can reduce the load of medications in patients with AD by also addressing cardiovascular, gastrointestinal, and other comorbidities. Using one drug to address multiple symptoms can reduce costs and improve medication compliance.
