Abstract
Pharmacological conditioning aims to protect the heart from myocardial ischemia-reperfusion injury (IRI). Despite extensive research in this area, today, a significant gap remains between experimental findings and clinical practice. This review provides an update on recent developments in pharmacological conditioning in the experimental setting and summarizes the clinical evidence of these cardioprotective strategies in the perioperative setting. We start describing the crucial cellular processes during ischemia and reperfusion that drive acute IRI through changes in critical compounds (∆GATP, Na+, Ca2+, pH, glycogen, succinate, glucose-6-phosphate, mitoHKII, acylcarnitines, BH4, and NAD+). These compounds all precipitate common end-effector mechanisms of IRI, such as reactive oxygen species (ROS) generation, Ca2+ overload, and mitochondrial permeability transition pore opening (mPTP). We further discuss novel promising interventions targeting these processes, with emphasis on cardiomyocytes and the endothelium. The limited translatability from basic research to clinical practice is likely due to the lack of comorbidities, comedications, and peri-operative treatments in preclinical animal models, employing only monotherapy/monointervention, and the use of no-flow (always in preclinical models) versus low-flow ischemia (often in humans). Future research should focus on improved matching between preclinical models and clinical reality, and on aligning multitarget therapy with optimized dosing and timing towards the human condition.

Reduction in mitochondrial ROS improves oxidative phosphorylation and provides resilience to coronary endothelium in non-reperfused myocardial infarction. Basic Res Cardiol 2023; 118:3. [PMID: 36639609 PMCID: PMC9839395 DOI: 10.1007/s00395-022-00976-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 12/30/2022] [Accepted: 12/30/2022] [Indexed: 01/15/2023]
Abstract
Recent studies demonstrated that mitochondrial antioxidant MnSOD that reduces mitochondrial (mito) reactive oxygen species (ROS) helps maintain an optimal balance between sub-cellular ROS levels in coronary vascular endothelial cells (ECs). However, it is not known whether EC-specific mito-ROS modulation provides resilience to coronary ECs after a non-reperfused acute myocardial infarction (MI). This study examined whether a reduction in endothelium-specific mito-ROS improves the survival and proliferation of coronary ECs in vivo. We generated a novel conditional binary transgenic animal model that overexpresses (OE) mitochondrial antioxidant MnSOD in an EC-specific manner (MnSOD-OE). EC-specific MnSOD-OE was validated in heart sections and mouse heart ECs (MHECs). Mitosox and mito-roGFP assays demonstrated that MnSOD-OE resulted in a 50% reduction in mito-ROS in MHEC. Control and MnSOD-OE mice were subject to non-reperfusion MI surgery, echocardiography, and heart harvest. In post-MI hearts, MnSOD-OE promoted EC proliferation (by 2.4 ± 0.9 fold) and coronary angiogenesis (by 3.4 ± 0.9 fold), reduced myocardial infarct size (by 27%), and improved left ventricle ejection fraction (by 16%) and fractional shortening (by 20%). Interestingly, proteomic and Western blot analyses demonstrated upregulation in mitochondrial complex I and oxidative phosphorylation (OXPHOS) proteins in MnSOD-OE MHECs. These MHECs also showed increased mitochondrial oxygen consumption rate (OCR) and membrane potential. These findings suggest that mito-ROS reduction in EC improves coronary angiogenesis and cardiac function in non-reperfused MI, which are associated with increased activation of OXPHOS in EC-mitochondria. Activation of an energy-efficient mechanism in EC may be a novel mechanism to confer resilience to coronary EC during MI.

Abstract
Objective Ischemia/reperfusion (IR)-induced myocardial arrhythmias are a common clinical manifestation in patients with myocardial infarction after reperfusion therapy. Mitochondria play a critical role in cardioprotection. Here, we investigated the effects of KH176 as a new mitochondrial-acting drug on IR-induced ventricular arrhythmias, mitochondrial function, pro-inflammatory cytokines production, and the role of mitochondrial ATP-dependent K (mK-ATP) channels in rats’ hearts. Methods The hearts of Sprague Dawley rats (250 ± 30 g; 36 rats) underwent 35 min of ischemia followed by 120 min of reperfusion. Myocardial in vivo ischemia was induced by ligation of the left anterior descending coronary artery. KH176 at concentrations of 10 and 50 μM was intraperitoneally injected to rats 10 min before reperfusion onset. Ventricular arrhythmias were quantified during reperfusion, and cardiac mitochondrial function, nitric oxide, and pro-inflammatory cytokines levels were measured by fluorometric, spectrophotometric, and ELISA techniques. Results Administration of KH176 significantly reduced lactate-dehydrogenase release and the number, duration, incidence, and severity of ventricular arrhythmias induced by reperfusion injury. IR-induced elevation of mitochondrial reactive oxygen species production, and cardiac pro-inflammatory cytokines TNF-α, IL-6, and IL-1β, as well as reduction of mitochondrial membrane potential, ATP and nitric oxide levels were significantly restored by KH176 at 50 μM. However, the blockade of mK-ATP channels by 5-hydroxydecanoate considerably inhibited the effects of KH176 on all parameters except nitric oxide. Conclusion KH176 showed strong cardiac antiarrhythmic effects on IR-induced injury through improving mitochondrial function and reducing inflammatory and oxidative responses, and these protective effects are mediated by cardiac mK-ATP channels.
