A groundbreaking electrocardiographic observation: "Isoelectric horizontal ST-segment with sharp ST-T angle" a novel sign for acute coronary syndrome.

Consecutive suspected acute coronary syndrome (ACS) cases were categorized into three groups: Group-1 (ST-depression), Group-2 (T-inversion), and Group-3 (remaining cases). Group-3 was subclassified into isoelectric horizontal ST-segment with sharp ST-T-angle (IHST) positive and IHST negative groups. They underwent serial high-sensitive Troponin-I testing.

Prevalence of Traditional Risk Factors in First-Degree Relatives of Patients With Established Cardiovascular Disease.

Introduction: World Health Organization (WHO)/International Society of Hypertension (ISH) risk prediction charts are useful for predicting 10-year combined myocardial infarction and stroke risk (fatal and non-fatal). Hence the current study was conducted to assess the 10-year risk of cardiovascular disease among adults in Ahmedabad, India.

Aims: The primary aim of the study was to assess the cardiovascular risk among first-degree relatives of patients attending the outpatient clinic.

Humming (Simple Bhramari Pranayama) as a Stress Buster: A Holter-Based Study to Analyze Heart Rate Variability (HRV) Parameters During Bhramari, Physical Activity, Emotional Stress, and Sleep.

Objective In this study, our goal was to understand the comparative impact of humming, physical activity, emotional stress, and sleep on several heart rate variability (HRV) parameters, including the stress index (SI), and to assess the effectiveness of humming (simple Bhramari) as a stress buster based on the HRV parameters. Methods This pilot study assessed the long-term HRV parameters of 23 participants in terms of four activities: humming (simple Bhramari), physical activity, emotional stress, and sleep. The single-channel Holter device measured the readings, and data was analyzed using Kubios HRV Premium software for time and frequency-domain HRV parameters, including the stress index.
