Left Atrial Peak Systolic Strain as an Indicator Pathway of Diastolic Dysfunction of the Left Ventricle.

BACKGROUND: Left atrial peak systolic strain (LA-PSS) imaging is an emerging index of left atrial function, and it was shown to be decreased in heart failure with preserved ejection fraction (EF). We aimed to determine whether LA-PSS could be used as an additional diagnostic parameter to current existing guidelines for the presence of left ventricle diastolic dysfunction (LVDD). MATERIALS AND METHODS: A total of 190 consecutive adult patients with cardiovascular risk factors and normal left ventricle EF with no prior history of heart failure were included in the study. Speckle tracking software was used to study ventricular parietal deformity, left ventricle global longitudinal systolic strain, and LA-PSS. RESULTS: The median left ventricle global longitudinal systolic strain was -19%, with a significant difference ( P < 0.001) between patients with normal diastolic function versus those with LVDD. The median LA-PSS was 33% (30% to 38%) ( P < 0.001). Most patients (61%) had grade 1 atrial dysfunction based on PSS (range 24%-35%). The analysis of the area under the receiver operating characteristic curve of the LA-PSS as a potential indicator pathway of LVDD was 67% [95% confidence interval (CI), 62-72], and 75% (95% CI, 70-80), when the indeterminate pattern was included. The decreased LA-PSS made it possible to reclassify patients with an indeterminate pattern of diastolic function in 96% of cases. CONCLUSIONS: These results support the potential role of LA-PSS as an additional parameter for the diagnosis of LVDD in patients with normal EF, and may be integrated into the guidelines for routine evaluation of patients.

Role of the Electrocardiographic MVP Risk Score (Morphology-Voltage-P Wave Duration) in Predicting the Development of Atrial Fibrillation in Patients With Systemic Arterial Hypertension.

BACKGROUND: There is a global tendency to emphasize the prevention and early diagnosis of diseases that have a great impact on public health. Atrial fibrillation (AF) has a prevalence affecting 1.5-2% of the general population. Certain variables of the P wave allow us to identify and stratify patients at risk of developing AF. MATERIALS AND METHODS: This is an observational, descriptive, and longitudinal study to determine the applicability of the electrocardiographic (ECG) morphology, voltage, and P wave duration (MVP) risk score to predict the development of AF in consecutive patients with systemic hypertension (SH) in an initial follow-up of 12 months. RESULTS: Initially, 104 patients were included, of whom 12 died during follow-up and 17 did not attend subsequent checkups during the COVID-19 pandemic; therefore, they were excluded. The study patients were 75, of whom AF was detected in 25 patients (33%). The average duration of the P wave was 120 ± 26 ms, the average voltage was 0.1 ± 0.5 Mv. The high-risk MVP ECG score had an [area under the curve, 0.69; 95% confidence intervals (CI), 0.59-0.79] and demonstrated a specificity and a positive predictive value of 100%, a negative predictive value of 76%, and a sensitivity of 40% for predicting the development of AF. CONCLUSIONS: The present study establishes for the first time that SH patients who possess a high-risk MVP ECG score have a significantly higher incidence of developing AF. The high-risk MVP Score has a specificity and a positive predictive value of 100% and a high negative predictive value with a moderate sensitivity for the prediction of the development of AF in SH patients.

Relationship of the T-wave Tpeak-Tend interval with conduction system disorders in arterial hypertension / Relación del intervalo Tpico-Tfinal de la onda T con trastornos del sistema de conducción en hipertensión arterial

Abstract Purpose: The Tpeak-Tend interval of the T wave has emerged as a new electrocardiographic marker of increased transmural dispersion of ventricular repolarization. We aimed to determine the presence of cardiac conduction system disorders in patients with systemic arterial hypertension (SAH) who have altered Tpeak-Tend interval of the T wave. Methods: The 67 patients with SAH were divided into two groups. Those with prolonged (≥ 77 ms) Tpeak-Tend intervals, 21 (31%) patients were in the study group. Those with normal (< 77 ms) Tpeak-Tend intervals, 46 (69%) patients were in the control group. Alteration of ventricular repolarization manifested as a prolongation of the Tpeak-Tend interval was detected by computerized electrocardiographic analysis tools. Results: The median value of QRS complex duration was significantly wider in the study group as compared to the control group (110 ± 12 ms vs. 94 ± 8 ms p < 0.001). There was a significantly greater incidence of left anterior hemiblock in the study group (14% vs. 0% p < 0.04). The median value of the QTc interval was significantly greater in the study group (440 ± 26 vs. 422 ± 15 p < 0.01). There was a significantly greater incidence of patients with prolonged QTc interval in the study group (33% vs. 11% p < 0.02). The median value of the Tpeak-Tend interval was significantly greater in the study group (84 ± 5 ms vs. 65 ± 4 ms p < 0.001), as well as, the Tpeak-Tend/QTc ratio in the study group (0.19 ± 0.1 vs. 0.16 ± 0.1 p < 0.001). Conclusion: There is a significantly greater ventricular repolarization disorders and abnormalities of the cardiac conduction system in SAH patients who possess altered Tpeak-Tend interval of the T wave.

Multivessel coronary thrombosis and acute myocardial infarction associated to two genetic mutations for thrombophilia / Trombosis coronaria de múltiples vasos e infarto agudo de miocardio asociado a dos mutaciones genéticas para trombofilia

Abstract Several studies suggest that gene mutations from thrombophilia may constitute a significant risk factor for coronary artery disease, especially in young patients with normal coronaries and non-significant lesions. It is presented a case of a 42-year-old male patient who arrived at the emergency room due to an acute myocardial infarction. The electrocardiogram showed an ST elevation with upward convexity of 4 mm from V1 to V4 and of 1 mm at V5 and V6. Cardiac enzymes were positive (troponin I 8.4 ng/dl, normal range < 1 ng/dl). It was found septum and apical hypokinesia, with an ejection fraction of 44%. The culprit lesion of the infarction was treated with primary angioplasty, successfully dilating the left anterior descending coronary artery. However, spontaneous thrombi appeared at the middle third of the circumflex artery, an area without occlusive lesions previously. A full laboratory assessment for prothrombotic state diseases revealed positivity for gene mutations at A1298C from the methylene tetrahydropholate reductase (MTHFR) and plasminogen activator inhibitor-1 (PAI-1). Gene mutations at A1298C from the MTHFR and PAI-1 should be considered in young patients with acute coronary syndrome, mainly when thrombi are found in non-culprit arteries with no or non-significant coronary lesions.

Resumen Las mutaciones genéticas de la trombofilia pueden constituir un factor de riesgo significativo para la enfermedad de la arteria coronaria, especialmente en pacientes jóvenes con arterias coronarias normales y lesiones no significativas. Se presenta el caso de un paciente masculino de 42 años con infarto agudo de miocardio. El electrocardiograma demostró una elevación del ST con convexidad ascendente de 4 mm de V1 a V4 y de 1 mm en V5 y V6. Las enzimas cardíacas fueron positivas (troponina I 8.4 ng/dl, rango normal < 1 ng/dl). Se observó hipocinesia septal y apical con fracción de eyección de 44%. La lesión causante del infarto fue tratada con angioplastia primaria, dilatando con éxito la arteria coronaria descendente anterior. Sin embargo, aparecieron trombos espontáneos en el tercio medio de la arteria circunfleja, que previamente no presentaba lesiones ateroscleróticas oclusivas. Al evaluar enfermedades protrombóticas se reveló positividad para mutaciones del gen A1298C de la metileno tetrahidrofolato reductasa (MTHFR) y del inhibidor del activador del plasminógeno (PAI-1) del genotipo heterocigoto 675G. Las mutaciones en A1298C del gen MTHFR y del PAI-1 deben considerarse en jóvenes con síndrome coronario agudo, principalmente cuando se encuentran trombos en arterias no culpables sin lesiones coronarias significativas.

Rol de la morfología y dispersión de la onda P en la predicción de fibrilación auricular

RESUMEN Las características anisotrópicas ocasionadas por un miocardio auricular patológico pueden jugar un papel importante en la creación de circuitos de reentrada al causar propagación no homogénea y discontinua del impulso en el miocardio auricular. Este miocardio auricular alterado puede generar bloqueo unidireccional, retraso de la conducción y ritmos auriculares reentrantes. En estas condiciones la onda P del electrocardiograma (ECG) puede mostrar alteraciones que pueden asociarse con arritmias auriculares y fibrilación auricular (FA). La dispersión de la onda P (DP) se considera un marcador no invasivo del ECG para el remodelado auricular y es predictor sensible y específico del desarrollo de FA. Se ha demostrado que el aumento de la duración de la onda P y la DP reflejan la prolongación del tiempo de conducción auricular dentro de la aurícula derecha y entre ambas aurículas, y una propagación auricular no homogénea y discontinua de los impulsos sinusales. Un valor de corte de 40 ms de la DP demostró tener una sensibilidad del 83%, una especificidad del 85% y un valor predictivo positivo del 89% para la identificación de pacientes con antecedentes de FA paroxística aislada. Los pacientes con alteración de la morfología de la onda P y dispersión de la onda P en el ECG tienen una gran susceptibilidad a desarrollar FA porque poseen electrogramas endocárdicos auriculares anormalmente prolongados y fraccionados, una duración de onda P significativamente mayor, un tiempo de conducción intraauricular e interauricular significativamente más largo, y una mayor incidencia de inducción de fibrilación auricular sostenida.

ABSTRACT The anisotropic characteristics caused by a pathological atrial myocardium can play an important role in the creation of reentry circuits by causing discontinuous and inhomogeneous impulse propagation in the atrial myocardium. This altered atrial myocardium can lead to unidirectional block, conduction delay, and reentrant atrial rhythms. Under these conditions, the P wave of the electrocardiogram (ECG) can demonstrate alterations that can be associated with atrial arrhythmias and atrial fibrillation (AF). The P-wave dispersion (PD) is considered a non-invasive ECG marker for atrial remodeling and is a sensitive and specific predictor of the development of AF. Increased P wave duration and PD have been shown to reflect prolonged atrial conduction time within the right atrium and between both atria, and discontinuous, inhomogeneous atrial propagation of sinus impulses. A cutoff value of 40 ms for PD was shown to have a sensitivity of 83%, a specificity of 85%, and a positive predictive value of 89% for the identification of patients with a history of isolated paroxysmal AF. Patients with abnormal P wave morphology and P wave dispersion on the ECG are highly susceptible to developing AF because they have abnormally prolonged and fractionated atrial endocardial electrograms, significantly longer P wave duration, and significantly longer intra-atrial and inter-atrial conduction time, and a higher incidence of sustained atrial fibrillation induction.

The relation between QRS complex fragmentation and segmental abnormalities of the myocardial contractility in patients with coronary artery disease.

BACKGROUND: Fragmented QRS (fQRS) is defined as any QRS complex with duration of less than 120 ms (ms) and at least one notch in the R or S wave in two or more leads belonging to the same coronary territory. The fQRS represents a delay in ventricular conduction caused by a myocardial scar associated to arrhythmic events. METHODS: This is a descriptive, retrospective, cross-sectional study of a total of 123 patientsadmitted with ischemic heart disease. The aim was to correlate the presence of fQRS in a conventional 12-leads electrocardiogram (ECG) with myocardial regional motility disorders. RESULTS: A total of 62% of the patients were male, the mean age was 63 ± 12 SD. fQRS was observed in 44% (64% men and 36% women), the most frequent location being the inferior wall (61%), followed by the anteroseptal and lateral walls (14% for both). Of the 36 patients with fQRS, 30 had segmental disorders, while 6 did not. Of the 45 patients without fQRS, 28 had segmental disorders, but 17 did not, which gives us a sensitivity of 52% (moderate SnNout) and specificity of 74% (high SpPin), with a positive predictive value of 83%, a negative predictive value of 38% and a prevalence of 72%. CONCLUSION: The presence of fQRS in the ECG has high specificity and a high positive predictive value of the existence of segmental myocardial motility disorders in patients with documented coronary artery disease.
