Special Issue Information

Dear Colleagues,

The role of the autonomic nervous system in chronotropic, inotropic, dromotropic, and lusitropic aspects of cardiac function is known. Thus, it is unsurprising that autonomic dysfunction participates in the development and progression of major cardiovascular diseases, including hypertension, myocardial infarction, heart failure, and sudden cardiac death. In fact, evidence has shown that cardiovascular dysfunction associated with myocardial infarction and heart failure, for example, is characterized by sympathetic hyperexcitation and withdrawal of the central parasympathetic tonus, leading to the study and use of therapies that reduce sympathetic activity to the heart, in the form of beta-blockade of adrenergic receptors or inhibition of the renin–angiotensin–aldosterone axis. Despite the universal use of these drugs, there is a remaining cardiovascular risk in treating patients and disease progression occurs, creating the need for new therapeutic approaches. In this context, interest in neuromodulation as a new therapeutic approach, with pharmacological therapies or through direct stimulation of arterial baroreceptors, the vagus nerve, and even renal denervation, has shown positive results in managing hypertension, heart failure and refractory ventricular arrhythmias. Furthermore, recently, new drugs, such as SGLT2 inhibitors and others, have also been proven to be effective in their neurohormonal action. Although these initial studies are promising, it is essential to advance our knowledge of the cardiovascular autonomic effects of both traditional and new pharmacological therapies, considering their possible pleiotropic effects or the remaining risk, for the development and implementation of precise neuromodulatory therapies. Therefore, this Special Issue is focused on the neuromodulatory effects of drugs and therapies in cardiovascular disease.

Recent studies have found increased cardiovascular mortality risk in patients with type 1 diabetes when compared to normoglycemic people, even when they were kept under good glycemic control. However, the mechanisms underlying this condition have yet to be fully understood. Using streptozotocin (STZ)-induced diabetic rats, we evaluated the effects of insulin replacement therapy on cardiac, autonomic, inflammatory, and oxidative stress parameters. Daily treatment with insulin administrated subcutaneously in the STZ-diabetic rats showed a reduction in hyperglycemia (>250 mg/dL) to normalized values. The insulin treatment was effective in preventing alterations in cardiac morphometry and systolic function but had no impact on diastolic function. Also, the treatment was not able to prevent the impairment of baroreflex-tachycardic response and systolic arterial pressure variability (SAP-V). A correlation was found between improvement of these autonomic parameters and higher levels of IL-10 and lower levels of oxidized glutathione. Our findings show that insulin treatment was not able to prevent diastolic, baroreflex, and SAP-V dysfunction, suggesting an outstanding cardiovascular risk, even after obtaining a good glycemic control in STZ-induced diabetic rats. This study shed light on a relatively large population of diabetic patients in need of other therapies to be used in combination with insulin treatment and thus more effectively manage cardiovascular risk.

Background: In this investigation, we explored the effects of pharmacological cholinergic stimulation on cardiac function and renal inflammation following acute myocardial infarction (AMI) in spontaneously hypertensive rats (SHRs). Methods: Adult male SHRs were randomized into three experimental groups: sham-operated; AMI + Veh (infarcted, treated with vehicle); and AMI + PY (infarcted, treated with the cholinesterase inhibitor, pyridostigmine bromide (PY)—40 mg/kg, once daily for seven days). Rats were euthanized 7 or 30 days post-surgery. The clinical parameters were assessed on the day before euthanasia. Subsequent to euthanasia, blood samples were collected and renal tissues were harvested for histological and gene expression analyses aimed to evaluate inflammation and injury. Results: Seven days post-surgery, the AMI + PY group demonstrated improvements in left ventricular diastolic function and autonomic regulation, and a reduction in renal macrophage infiltration compared to the AMI + Veh group. Furthermore, there was a notable downregulation in pro-inflammatory gene expression and an upregulation in anti-inflammatory gene expression. Analysis 30 days post-surgery showed that PY treatment had a sustained positive effect on renal gene expression, correlated with a decrease in biomarkers, indicative of subclinical kidney injury. Conclusions: Short-term cholinergic stimulation with PY provides both cardiac and renal protection by mitigating the inflammatory response after AMI. Full article
