The DEX0.5 group received a continuous infusion of dexmedetomidine at a rate of 0.5 μg·kg⁻1·h⁻1, while the DEX1 group received it at a rate of 1 μg·kg⁻1·h⁻1 during the induction of anesthesia, which was maintained for 24 hours. The primary outcome was the incidence of atrial fibrillation, while the secondary outcomes included other tachyarrhythmias, bradycardia, hypotension, duration of mechanical ventilation, time spent in the cardiac care unit, and length of hospitalization. A total of 101 patients were included in the DEX0.5 group, while 104 patients were included in the DEX1 group. The incidence of atrial fibrillation was significantly lower in the DEX1 group compared to the DEX0.5 group (10.6% vs. 21.8%, P = 0.029). Additionally, the duration of mechanical ventilation was shorter in the DEX1 group than in the DEX0.5 group (8.9 vs. 15.2 hours, P = 0.018). Logistic regression analyses were conducted to investigate the factors influencing atrial fibrillation. The results indicated that the dose of dexmedetomidine was the only independent predictor (odds ratio = 0.394, 95% confidence interval 0.172 to 0.903, P = 0.028). Compared to a continuous infusion of 0.5 μg·kg⁻1·h⁻1, this study suggested that administering dexmedetomidine at a dose of 1 μg·kg⁻1·h⁻1 for 24 hours is effective in reducing the incidence of atrial fibrillation following cardiac surgery.","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143028837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, they serve as key targets for therapeutic interventions in cardiovascular diseases. Cell function is substantially influenced by the concentration of free cytosolic calcium (Ca 2+ ) and the voltage across the plasma membrane. These characteristics are known to be regulated by Ca 2+ -permeable nonselective cationic channels, although our knowledge of these channels is still inadequate. The transient receptor potential (TRP) superfamily comprises of many nonselective cation channels with diverse Ca 2+ permeability. Canonical or classical TRP (TRPC) channels are a subgroup of the TRP superfamily that are expressed ubiquitously in mammalian cells. TRPC channels are multidimensional signaling protein complexes that play essential roles in a variety of physiological and pathological processes in humans, including cancer, neurological disorders, cardiovascular diseases, and others. The objective of this article was to focus on the role that TRPC channels play in the cardiovascular system. The role of TRPC channels will be deeply discussed in cardiovascular pathology. Together, a critical element in developing novel treatments that target TRPC channels is comprehending the molecular mechanisms and regulatory pathways of TRPC channels in related cardiovascular diseases and conditions.","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"21-34"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142466351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although concerns about fetal toxicity have traditionally limited the use of lisinopril in women of reproductive age, recent American College of Obstetricians and Gynecologists guidelines promote aggressive treatment of hypertension, which may require the use of pharmacologic agents not previously considered in the postpartum period. We aimed to estimate infant exposure to maternal lisinopril through breast milk and report the tolerance of the breastfed infant. Five volunteers taking lisinopril provided samples of their human milk and their associated health information for research through the InfantRisk Center Human Milk Biorepository. The milk pharmacokinetics of lisinopril were measured using liquid chromatography-mass spectrometry. The mean milk concentration of lisinopril was 0.49 ng/mL per 10 mg daily dose. The relative infant dose was 0.06% for lisinopril, more than 100 times lower than the standard 10% safety threshold. The minimal transfer of lisinopril into human milk in this study suggests the drug is unlikely to pose a clinically significant risk to healthy breastfed infants.","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"84-87"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142466353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are 3 distinct forms of autophagy: macroautophagy, microautophagy, and chaperone-mediated autophagy. In the heart, autophagy is regulated mainly through mitophagy because of the metabolic changes of cardiomyocytes caused by ischemia and hypoxia. Myocardial remodeling is characterized by gradual heart enlargement, cardiac dysfunction, and extraordinary molecular changes. Cardiac remodeling after myocardial infarction is almost inevitable, which is the leading cause of heart failure. Autophagy has a protective effect on myocardial remodeling improvement. Autophagy can minimize cardiac remodeling by preventing misfolded protein accumulation and oxidative stress. This review summarizes the nestest molecular mechanisms of autophagy and myocardial remodeling, the protective effects, and the new target of autophagy medicine in cardiac remodeling.

Adult people living with HIV (PLWH) receiving ART newly initiated on an oral P2Y12inh were included. The primary outcome was the incidence of DDI between ART and P2Y12inh at P2Y12inh initiation.

Ninety-three PLWH (60%) had a DDI at time of P2Y12inh initiation, with highest incidence in the clopidogrel group (n = 84, 71%), followed by ticagrelor (n = 9, 39%) and none with prasugrel. Within 1 year, MACE occurred in 12 PLWH, with DDI present at the time of 4 events. There were 29 bleeding events occurring within 1 year, including 17 events with DDI at time of event. However, 88% of DDI in patients with bleeding events were expected to decrease the efficacy of P2Y12inh. Though we observed high incidence of DDI between P2Y12inh and ART in PLWH, MACE and bleeding events at 1 year did not correlate with DDI. It remains unknown whether DDI presence at P2Y12inh initiation with ART causes clinical outcomes of concern, or whether underlying platelet reactivity in PLWH is associated with these events.","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"75-83"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142621234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reporting odds ratio was used as an estimate for detecting AKI signal. A total of 659,573 reports on at least 1 glucose-lowering drug and/or ARNI were obtained. Of the 413 reports on cotherapy of SGLT2Is and ARNI, 99 (24.0%) reports mentioned AKI. Overall, the AKI reporting rate significantly increased in cotherapy (adjusted reporting odds ratio, 95% confidence interval: 8.04, 6.20-10.42, P < 0.001), with a stronger AKI signal in cotherapy of canagliflozin and ARNI (16.82, 3.75-75.57, P < 0.001). Specifically, no increased AKI signal was detected in patients with heart failure (HF) receiving cotherapy after adjustment for sex and age (HF: 1.27, 0.89-1.80, P = 0.189; HF plus diabetes: 2.08, 0.99-4.40, P = 0.055; or HF plus hypertension: 1.69, 0.53-5.35, P = 0.376), whereas enhanced AKI signals were detected in patients with diabetes (20.57, 11.93-35.46, P < 0.001), hypertension (4.30, 1.98-9.37, P < 0.001), or diabetes plus hypertension (5.44, 1.92-15.43, P = 0.001).

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) emerged as one of the key pharmacotherapy options for both reduced and preserved ejection fraction, providing cardio- and renoprotection and improving mortality and cardiovascular (CV) outcomes. The pleiotropism of SGLT2i has led to multiple efforts to understand their distinct pathophysiologic interactions with various pathways, including microcirculation, endothelial dysfunction, and inflammation. More recently, the role of SGLT2i on the sympathetic nervous system (SNS) is starting to be recognized, especially because observations of retained or reduced heart rate despite volume contraction have been noted by investigators in the large clinical trials testing the safety and efficacy of these agents. Both preclinical and clinical studies have been performed, with conflicting results. Interestingly, in both settings, although there are indications of SNS modulation by SGLT2i, other studies contradict such findings, without showing, however, worsening of the autonomic homeostasis. Given the importance of neuromodulation in HF, in both pharmacologic and interventional therapies, in this review, we aim to describe the role of SNS in CV disease, focusing on HF, analyze preclinical and clinical data regarding the efficacy of SGLT2i in modulating autonomic dysfunction by examining various markers of SNS activation, and provide the most plausible theoretical backgrounds on the mechanism of benefit of SNS from the inhibition of SGLT2 receptors.","PeriodicalId":15212,"journal":{"name":"Journal of Cardiovascular Pharmacology","volume":" ","pages":"12-20"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142466354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
