Computer-Interpreted Electrocardiograms: Impact on Cardiology Practice

Abstract In the realm of modern cardiology, the integration of computer-interpreted electrocardiograms (CI-ECGs) has marked the beginning of a new era of diagnostic precision and efficiency. Contemporary electrocardiogram (ECG) integration systems, applying algorithms and artificial intelligence, have modernized the interpretation of heart rhythms and cardiac morphology. Due to their ability to rapidly analyze and interpret ECG recordings CI-ECGs have already profoundly impacted clinical practice. This review explores the evolution of computer interpreted ECG technology, evaluates the pros and cons of current automatic reporting systems, analyzes the growing role of artificial intelligence on ECG interpretation technologies, and discusses emerging applications that may have transformative effects on patient outcomes. Emphasis is placed on the role of ECGs in the automatic diagnosis of occlusion myocardial infarctions (OMI). AI models enhance accuracy and efficiency in ECG interpretation, offering insights into cardiac function and aiding timely detection of concerning patterns for accurate clinical diagnoses. The shift to AI-driven diagnostics has emphasized the importance of data in the realm of cardiology by improving patient care. The integration of novel AI models in ECG analysis has created a promising future for ECG diagnostics through a synergistic fusion of feature-based machine learning models, deep learning approaches, and clinical acumen. Overall, CI-ECGs have transformed cardiology practice, offering rapid, accurate, and standardized analyses. These systems reduce interpretation time significantly, allowing for quick identification of abnormalities. However, sole reliance on automated interpretations may overlook nuanced findings, risking diagnostic errors. Therefore, a balanced approach in integrating automated analysis with clinical judgment is necessary.

ABSTRACT Objectives. To explore the frequency and impact of violence against healthcare workers in Argentina and to compare it with the rest of their Latin American peers during the COVID-19 pandemic. Materials and methods. A cross-sectional study was conducted by applying an electronic survey on Latin American medical and non-medical personnel who carried out health care tasks since March 2020. We used Poisson regression to estimate crude (PR) and adjusted (aPR) Prevalence Ratios with their respective 95% confidence intervals. Results. A total of 3544 participants from 19 countries answered the survey; 1992 (56.0%) resided in Argentina. Of these, 62.9% experienced at least one act of violence; 97.7% reported verbal violence and 11.8% physical violence. Of those who were assaulted, 41.5% experienced violence at least once a week. Health personnel from Argentina experienced violence more frequently than those from other countries (62.9% vs. 54.6%, p<0.001), and these events were more frequent and stressful (p<0.05). In addition, Argentinean health personnel reported having considered changing their healthcare tasks and/or desired to leave their profession more frequently (p<0.001). In the Poisson regression, we found that participants from Argentina had a higher prevalence of violence than health workers from the region (14.6%; p<0.001). Conclusions. There was a high prevalence of violence against health personnel in Argentina during the COVID-19 pandemic. These events had a strong negative impact on those who suffered them. Our data suggest that violence against health personnel may have been more frequent in Argentina than in other regions of the continent.

Conciencia de enfermedad cardiovascular y conocimiento sobre factores de riesgo y prevención cardiovascular: resultados chilenos de encuesta SIAC cono sur / Awareness of risk factors and prevention of cardiovascular disease in chile: SIAC cono sur survey

Resumen La conciencia de la enfermedad cardiovascular (ECV) en mujeres es crucial para prevenir futuros eventos cardiovasculares. En Chile, la percepción sobre ECV es baja. Objetivo: Actualizar el grado de conocimiento de las chilenas sobre ECV. Método: Estudio de corte transversal realizado a través de encuesta online a mujeres entre 20 y 70 años de edad, residentes en Chile durante marzo 2020. La invitación se efectuó a través de redes sociales. La muestra fue no probabilística, ponderándose por edad, nivel socioeconómico y región de residencia (Región Metropolitana, Coquimbo, Valparaíso, Bío-Bío). Resultados: Se obtuvieron 1227 cuestionarios validados. La muestra ponderada correspondió a 900 mujeres. La percepción de ECV como principal causa de muerte fue de 8%, menor que las correspondientes a cáncer de mama (44%) y muerte violenta / homicidio (20%). Como principal problema de salud, la opción más percibida fue cáncer general (39%), seguido de diabetes (18%). Sólo 6 % refirió la ECV como el principal problema. Los principales accesos a la información sobre ECV fueron la internet y las redes sociales (64%, mayor en <30 años), y en el consultorio (32%). La opresión o dolor en el pecho fueron los síntomas más reconocidos asociados al infarto, siendo más seleccionado por mujeres con nivel educacional alto (p< 0.05). Conclusión: Persiste una baja percepción del riesgo de la ECV como principal causa de muerte y problema de salud en mujeres chilenas, aunque tienen acceso a la información y reconocen síntomas de infarto. Es necesario adaptar las estrategias comunicacionales para incrementar la percepción de riesgo CV.

Abstract Awareness of cardiovascular disease (CVD) in women is crucial to prevent cardiovascular events. According to prior information the perception and knowledge about CVD in Chile is extremely low. The aim of this study was to update the information about awareness of CVD in Chilean women. Method: Cross-sectional study carried out through an online survey. Data was obtained from women between 20 and 70 years old during March 2020. Social networks were used to recruit participants. The sample was non-probabilistic, weighted by age, socio-economic level and region of residence (Metropolitan Region, Coquimbo, Valparaíso, Bío-Bío). Results: 1227 validated surveys were obtained. The weighted sample corresponded to 900 women. CVD was perceived as the main cause of death in 8% of women, compared to higher degrees of perception for breast cancer (44%) and violent death/homicide (20%). CVD was perceived as the main health problem by only 6% of women, compared to cancer (39%) and diabetes (18%). The primary source of information about CVD were the internet and social networks (64%,higher in women <30 years old), and the doctor's office (32%). Chest tightness or pain as symptoms associated with a heart attack were significantly more recognized by respondents with a high educational level (p<0.05). Conclusion: An extremely low awareness about CVD as the main cause of death and health problem is persistent in Chilean women, notwithstanding that they have access to information and recognize symptoms of a heart attack. It is necessary to modify our communication strategies to increase the perception of CV risk in Chilean women.

Dapagliflozin and Kidney Outcomes in Hospitalized Patients with COVID-19 Infection: An Analysis of the DARE-19 Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: Patients who were hospitalized with coronavirus disease 2019 (COVID-19) infection are at high risk of AKI and KRT, especially in the presence of CKD. The Dapagliflozin in Respiratory Failure in Patients with COVID-19 (DARE-19) trial showed that in patients hospitalized with COVID-19, treatment with dapagliflozin versus placebo resulted in numerically fewer participants who experienced organ failure or death, although these differences were not statistically significant. We performed a secondary analysis of the DARE-19 trial to determine the efficacy and safety of dapagliflozin on kidney outcomes in the overall population and in prespecified subgroups of participants defined by baseline eGFR. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The DARE-19 trial randomized 1250 patients who were hospitalized (231 [18%] had eGFR <60 ml/min per 1.73 m2) with COVID-19 and cardiometabolic risk factors to dapagliflozin or placebo. Dual primary outcomes (time to new or worsened organ dysfunction or death, and a hierarchical composite end point of recovery [change in clinical status by day 30]), and the key secondary kidney outcome (composite of AKI, KRT, or death), and safety were assessed in participants with baseline eGFR <60 and ≥60 ml/min per 1.73 m2. RESULTS: The effect of dapagliflozin versus placebo on the primary prevention outcome (hazard ratio, 0.80; 95% confidence interval, 0.58 to 1.10), primary recovery outcome (win ratio, 1.09; 95% confidence interval, 0.97 to 1.22), and the composite kidney outcome (hazard ratio, 0.74; 95% confidence interval, 0.50 to 1.07) were consistent across eGFR subgroups (P for interaction: 0.98, 0.67, and 0.44, respectively). The effects of dapagliflozin on AKI were also similar in participants with eGFR <60 ml/min per 1.73 m2 (hazard ratio, 0.71; 95% confidence interval, 0.29 to 1.77) and ≥60 ml/min per 1.73 m2 (hazard ratio, 0.69; 95% confidence interval, 0.37 to 1.29). Dapagliflozin was well tolerated in participants with eGFR <60 and ≥60 ml/min per 1.73 m2. CONCLUSIONS: The effects of dapagliflozin on primary and secondary outcomes in hospitalized participants with COVID-19 were consistent in those with eGFR below/above 60 ml/min per 1.73 m2. Dapagliflozin was well tolerated and did not increase the risk of AKI in participants with eGFR below or above 60 ml/min per 1.73 m2.

Rabies and the Heart.

As one of the neglected diseases, rabies is as a highly fatal viral infection, most prevalent in low- and middle-income regions, which produces a substantial health and economic burden. It mainly affects the central nervous system causing encephalitis, however extraneuronal involvement has been documented. Cardiac structures may be involved and can play a role in the severity of the disease. Most of the existing literature comes from case reports and case series where cardiac involvement results in myocarditis and cardiac arrhythmias. As part of the "Neglected Tropical Diseases and Other Infectious Diseases Involving the Heart" (NET-HEART Project), the objective of this article is to review all the information available on the cardiac involvement of this disease.

Blood pressure control and cardiovascular risk profile in hypertensive patients under specialist care in Argentina: Results from the CHARTER study.

Worldwide, hypertension control rate is far from ideal. Some studies suggest that patients treated by specialists have a greater chance to achieve control. The authors aimed to determine the BP control rate among treated hypertensive patients under specialist care in Argentina, to characterize patients regarding their cardiovascular risk profile and antihypertensive drug use, and to assess the variables independently associated with adequate BP control. The authors included adult hypertensive patients under stable treatment, managed in 10 specialist centers across Argentina. Office BP was measured thrice with a validated oscillometric device. Adequate BP control was defined as an average of the three readings <140/90 mm Hg (and <150/90 in patients older than 80 years). The authors estimated the proportion of adequate BP control and the variables independently associated with it through a multiple conditional logistic regression model. Among the 1146 included patients, 48.2% were men with a mean age of 63.5 (±13.1) years old. Mean office BP was 135.3 (±14.8)/80.8 (±10) mm Hg, with a 64.8% (95% CI: 62%-67.6%) of adequate control. The mean number of antihypertensive drugs was 2.1 per participant, the commonest being angiotensin receptor blockers and calcium channel blockers. In multivariable analysis, only female sex was a predictor of adequate BP control (OR 1.33 [95% CI 1.02-1.72], P = .04). In conclusion, almost 65% of hypertensive patients treated in specialist centers in Argentina have adequate BP control. The challenge for future research is to define strategies in order to translate this control rate to the primary care level, where most patients are managed.

Health perception in menopausal women.

AIM: The aim of this study is to find whether the worsening of health perception was related to the menopausal (MNP) state or to its negative consequences on cardiometabolic risk factors (CMRF) and the presence of depression/anxiety. METHODS: In this study, 2,562 women, 1,357 (53%) MNP and 1,205 (47%) non-MNP, were analyzed. Blood pressure, heart rate, body mass index, waist circumference, and depression/anxiety screening using the Hospital Depression/Anxiety Scale (HADS) were measured. We collected a blood sample in fasting state for glycemia, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides. Logistic regression models were fitted with a backward method from the potentially confusing variables of the menopause study groups. RESULTS: Age 49.4 (±15.9) years; 10.1% belonged to semi-rural population; 87.5% had children. Regarding the educational level, 22.1% had <5 years of education, 31.3% had between 6 and 7 years, 33.4% had between 8 and 12 years, and 13.2% had >12 years of education. The prevalence of CMRF was significantly higher in MNP women, except for smoking. We did not find any differences in the prevalence of depression or anxiety between MNP and non-MNP women. Health was perceived as worse among MNP women (P<0.05) and patients over 45 years of age than patients younger than 45 years. We found a relationship between the negative health perception with metabolic syndrome, depression, and anxiety, having children, smoking, residing in rural area, and low educational level; nevertheless, it is not correlative with MNP status. CONCLUSION: Perceived health should be viewed as a multifaceted condition related to social circumstances, and various symptoms in women, including menopause symptoms, but not with MNP state itself.

Association Between Hypertension, Menopause, and Cognition in Women.

The aim of this study was to investigate the cognitive state in women and its relation to menopause and hypertension (HTN). The authors included 1034 women aged 47.13±15.71 years. The prevalence of HTN was 47.1%, with 67.8% of patients treated and 48.6% controlled. Cognitive impairment was higher among hypertensive menopausal (mini-Boston Naming Test: 7.4±3.1 vs 8.5±2.4, P<.001; Clock-Drawing Test: 5.2±2 vs 5.6±1.6, P<.01). Using logistic regression adjusted by age and education level, statistical differences were found in the results from the mini-Boston Naming Test between menopausal hypertensive vs menopausal normotensive women (odds ratio, 1.48; 95% confidence interval, 1.06-2.07; P=.021), and no difference between nonmenopausal hypertensive vs menopausal normotensive women (odds ratio, 0.89; 95% confidence interval, 0.51-1.57; P=.697). The P interaction between both groups was significant (P=.038). The possibility of alteration in cortical functions in menopausal hypertensive woman showed a relative increment of 48% (P=.021). The association between HTN and menopause increases the possibility of compromising the semantic memory by 50%.

Cognition and vascular risk factors: an epidemiological study.

We conducted an epidemiological approach to identify the negative impact of the vascular risk factors (such as hypertension, diabetes and hypercholesterolemia) over cognition. The interesting aspect of this study was that the survey was conducted in all age groups through a voluntary call (n = 1365; ≥18 years old, both sexes; age 49 ± 15 y, female 75.7%). Thus, we demonstrated that the use of a Minimum Cognitive Examination (MCE), a brief, simple, and easy managed neuropsychological evaluation, detected a greater number of people with cognitive decline surpassing to the Minimal Mental Statement Examination alone (14.5% of the participants showed MMSE ≤24, 34,6% showed dys-executive function, and 45,8% memory impairment. Out of the 4 studied RF, the only one that was not related to cognitive impairment was dyslipemia. Finally, we noted the importance of cognitive state early detection in all age groups, even in the youngest group. Acting in the middle of the life stages, we can prevent or delay the onset of a disease in adults, nowadays incurable: dementia.

Cognitive evolution in hypertensive patients: a six-year follow-up.

BACKGROUND: Several studies have examined the links between hypertension, vascular damage, and cognitive impairment. The functions most commonly involved seem to be those associated with memory and executive function. AIMS: 1) to report the cognitive evolution in a cohort of hypertensive patients, 2) to identify the affected domains, and 3) to correlate the results obtained with blood pressure measurements. MATERIALS AND METHODS: Observational 6-year follow-up cohort study including both males and females aged≥65 and ≤80 years, and hypertensive patients under treatment. Patients with a history of any of the following conditions were excluded: stroke, transient ischemic attack, diabetes mellitus, atrial fibrillation, cardiac surgery, dementia, or depression. Four neurocognitive evaluations were performed (at baseline and every 2 years). The tests used evaluated memory and executive function domain. Blood pressure was measured on every cognitive evaluation. RESULTS: Sixty patients were followed for 76.4±2.8 months. The average age at baseline was 72.5±4.2 and 77.9±4.6 at 6 years (65% were women). Two patients were lost to follow up (3.3%) and 8 patients died (13.3%).The density incidence for dementia was 0.6% patients per year (pt/y) (n=3) and for depression was 1.6% pt/y (n=12). No changes were observed in either memory impairment or the Mini Mental State Examination (MMSE) results (p=ns) during follow-up. A progressive impairment of the executive function was shown regardless of the blood pressure measurements. CONCLUSION: 1) the incidence of dementia doubled to general population, 2) the initial memory impairment did not change during the evaluation period, 3) cognitive impairment worsened in the areas related to executive function (prefrontal cortex) regardless of the adequacy of anti-hypertensive treatment and blood pressure values.
