Memory T-Waves: An Uncharted Territory in T-Wave Inversions.

T-wave inversions on electrocardiograms (ECGs) can present a diagnostic challenge due to their association with various underlying causes. One less-explored cause is memory T-waves, a phenomenon characterized by T-wave inversions, often seen in chest and inferior leads, following a period of abnormal ventricular conduction. In this case report, we discuss the intriguing case of an 80-year-old woman who recently underwent percutaneous coronary intervention (PCI) for a myocardial infarction and subsequently developed memory T-waves.

Patients hospitalised with heart failure across different waves of the COVID-19 pandemic show consistent clinical characteristics and outcomes.

Background: During the first wave of the COVID-19 pandemic, admissions for cardiovascular disease, including Heart Failure (HF), were reduced. Patients hospitalised for HF were sicker and with increased in-hospital mortality. So far, whether following waves had a different impact on HF patients is unknown.

Long-term outcomes after heart failure hospitalization during the COVID-19 pandemic: a multisite report from heart failure referral centers in London.

Aims: Patients hospitalized for heart failure (HF) had worse in-hospital outcomes during the first wave of the COVID-19 pandemic. However, their long-term outcomes are unknown. We describe long-term outcomes among patients who survived to hospital discharge compared with patients hospitalized in 2019 from two referral centers in London during the COVID-19 pandemic.

Temporal trends in decompensated heart failure and outcomes during COVID-19: a multisite report from heart failure referral centres in London.

Aims: Admission rates for acute decompensated heart failure (HF) declined during the COVID-19 pandemic. However, the impact of this reduction on hospital mortality is unknown. We describe temporal trends in the presentation of patients with acute HF and their in-hospital outcomes at two referral centres in London during the COVID-19 pandemic.

The impact of COVID-19 on heart failure hospitalization and management: report from a Heart Failure Unit in London during the peak of the pandemic.

Aims: To examine the impact of COVID-19 on acute heart failure (AHF) hospitalization rates, clinical characteristics and management of patients admitted to a tertiary Heart Failure Unit in London during the peak of the pandemic.

Methods And Results: Data from King's College Hospital, London, reported to the National Heart Failure Audit for England and Wales, between 2 March-19 April 2020 were compared both to a pre-COVID cohort and the corresponding time periods in 2017 to 2019 with respect to absolute hospitalization rates. Furthermore, we performed detailed comparison of patients hospitalized during the COVID-19 pandemic and patients presenting in the same period in 2019 with respect to clinical characteristics and management during the index admission.

In-hospital management and intermediate term outcomes in stable patients with ST segment elevation myocardial infarction presenting between 12-48 hours of symptom onset versus 2-7 days after the onset of chest pain; a single center study.

Objective: To evaluate hospital management, revascularisation and intermediate-term major adverse cardiac events amongst ST elevation myocardial infarction patients and to compare them in early and late presentations. .

Methods: The retrospective study was conducted at Tabba Heart Institute, Karachi, and comprised data from July 2013 to December 2016.

Management, hospital outcome and revascularization trends in non-ST elevation myocardial infarction with high GRACE risk score.

Objective: To assess clinical characteristics, management strategies and in-hospital outcome among high-risk patients of non-ST elevation myocardial infarction.

Methods: The retrospective cross-sectional study was conducted at Tabba Heart Institute, Karachi, and comprised data from July 2013 to December 2016 of adult non-ST elevation myocardial infarction patients who had first cardiac event having Global Registry of Acute Coronary Eventsrisk score>140. Subcategories were formed on the basis of score range 140-159, 160-189 and ?190.
