“…Atrial and ventricular strain parameters have proven to be robust markers of future arrhythmia events in various cardiovascular diseases [45][46][47][48]. Ersbøll et al conducted a prospective study investigating the utility of global longitudinal strain in predicting VAs in the acute phase of myocardial infarction.…”

(1) Objective: Myocarditis can be associated with ventricular arrhythmia (VA), individual non-invasive risk stratification through cardiovascular magnetic resonance (CMR) is of great clinical significance. Our study aimed to explore whether left atrial (LA) and left ventricle (LV) myocardial strain serve as independent predictors of VA in patients with myocarditis. (2) Methods: This retrospective study evaluated CMR scans in 141 consecutive patients diagnosed with myocarditis based on the updated Lake Louise criteria (29 females, mean age 41 ± 20). The primary endpoint was VA; this encompassed ventricular fibrillation, sustained ventricular tachycardia, nonsustained ventricular tachycardia, and frequent premature ventricular complexes. LA and LV strain function were performed on conventional cine SSFP sequences. (3) Results: After a median follow-up time of 23 months (interquartile range (18–30)), 17 patients with acute myocarditis reached the primary endpoint. In the multivariable Cox regression analysis, LA reservoir (hazard ratio [HR] and 95% confidence interval [CI]: 0.93 [0.87–0.99], p = 0.02), LA booster (0.87 95% CI [0.76–0.99], p = 0.04), LV global longitudinal (1.26 95% CI [1.02–1.55], p = 0.03), circumferential (1.37 95% CI [1.08–1.73], p = 0.008), and radial strain (0.89 95% CI [0.80–0.98], p = 0.01) were all independent determinants of VA. Patients with LV global circumferential strain > −13.3% exhibited worse event-free survival compared to those with values ≤ −13.3% (p < 0.0001). (4) Conclusions: LA and LV strain mechanism on CMR are independently associated with VA events in patients with myocarditis, independent to LV ejection fraction, and late gadolinium enhancement location. Incorporating myocardial strain parameters into the management of myocarditis may improve risk stratification.

“…Пороговой величиной в данном случае можно рассматривать показатель глобальной продольной деформации ЛЖ −16%, тогда как нормальные показатели лежат в пределах от −18% до −25%. Преимуществом данной технологии является способность предсказывать кардиоваскулярные события при нормальной ФВ ЛЖ [29,30]. Определение показателей деформации ЛЖ при рутинном измерении артериального давления с помощью соответствующего программного обеспечения позволяет также построить кривые «давление - деформация», которые можно рассматривать как эквивалент кривых «давление - объем», отражающие состояние миокардиальной работы.…”

Premature ventricular complexes (PVC) is one of the most common arrhythmias in daily clinical practice. In the vast majority of cases, PVC has a good prognosis, but in some cases it can cause serious, including lifethreatening complications. On the other hand, asymptomatic, frequent PVC can lead to the development of left ventricular (LV) systolic dysfunction, which can be reversible with effective therapy. Medications remain the mainstay of therapy for PVC. However, the effectiveness of some drugs is quite low, while other drugs have significant side and proarrhythmic effects. Technological advances in the field of radiofrequency (RF) catheter ablation in recent years have opened up tremendous prospects in the radical correction of PVC and put forward this approach in selective cases as the method of choice. However, this invasive technology may at the same time carry the risks of serious complications, which can occur in up to 5% of individuals undergoing this procedure. The potential risks of RF catheter ablation largely depend on the accessibility of the ectopic focus. In this regard, differential diagnosis of the source of ectopia is of great importance for a balanced assessment of the possible risks and effectiveness of this invasive method. Standard diagnostic methods, such as 12-lead electrocardiography, Holter monitoring and echocardiography, allow in many cases to make the best decision regarding further management tactics. Frequent, asymptomatic PVC needs in annual monitoring to prevent LV systolic dysfunction development in cases high potential RF catheter ablation risks and drugs ineffectiveness. Traditional echocardiography and novel ultrasound technologies can help in this difficult of choice cases.

Global longitudinal strain has been established as a reliable tool to assess global left ventricular function and a marker of subclinical left ventricular dysfunction unrecognized by the ejection fraction. On the other hand, ventricular arrhythmias are the most common cause of sudden cardiac death. Their early detection is a challenge. Possible prognostic markers for the risk of ventricular arrhythmias are discussed in the literature – electrocardiographic, cardiac magnetic resonance, computed tomography, radionuclide imaging, and markers from new echocardiographic techniques. Of the latter, at this stage of knowledge, several markers have been discussed as informative for predicting ventricular arrhythmias – global longitudinal strain, radial strain and mechanical dispersion, and most recently, myocardial work. As far as we are informed, global longitudinal strain is particularly useful in patients with normal echocardiographic parameters such as left ventricular ejection fraction, left atrial diameter, left ventricular wall thickness, and aortic root. The relationship between mechanical dispersion and ventricular arrhythmias has been widely studied. The relationship has been studied more in some patient populations – heart failure, ischemic heart disease, long QT syndrome and arrhythmogenic cardiomyopathy, congenital heart disease. The role of mechanical dispersion as a predictor of ventricular arrhythmias in metabolic syndrome is scarce.
