ECG Blog #421 — Has there been a Recent MI?

Ken Grauer, MD

What if you were asked to interpret the ECG in Figure-1 ? How would YOU interpret the rhythm? Even without the benefit of any history — Has there been a recent MI? Figure-1: The initial ECG in today's case. ( To improve visualization — I've digitized the original ECG using PMcardio ). MY Approach to Today’s Tracing: As always — I favor beginning assessment with a quick look at the long lead rhythm strips at the bottom of the tracing.

Single-cell DNA sequencing reveals a high incidence of chromosomal abnormalities in human blastocysts

Journal of Clinical Investigation - Cardiology

Aneuploidy, a deviation from the normal chromosome copy number, is common in human embryos and is considered a primary cause of implantation failure and early pregnancy loss. Meiotic errors lead to uniformly abnormal karyotypes, while mitotic errors lead to chromosomal mosaicism: the presence of cells with at least 2 different karyotypes within an embryo.

Disassembly of the TRIM56-ATR complex promotes cytoDNA/cGAS/STING axis–dependent intervertebral disc inflammatory degeneration

Journal of Clinical Investigation - Cardiology

As the leading cause of disability worldwide, low back pain (LBP) is recognized as a pivotal socioeconomic challenge to the aging population and is largely attributed to intervertebral disc degeneration (IVDD). Elastic nucleus pulposus (NP) tissue is essential for the maintenance of IVD structural and functional integrity. The accumulation of senescent NP cells with an inflammatory hypersecretory phenotype due to aging and other damaging factors is a distinctive hallmark of IVDD initiation and p

PD-1 or CTLA-4 blockade promotes CD86-driven Treg responses upon radiotherapy of lymphocyte-depleted cancer in mice

Journal of Clinical Investigation - Cardiology

Radiotherapy (RT) is considered immunogenic, but clinical data demonstrating RT-induced T cell priming are scarce. Here, we show in a mouse tumor model representative of human lymphocyte–depleted cancer that RT enhanced spontaneous priming of thymus-derived (FOXP3+Helios+) Tregs by the tumor. These Tregs acquired an effector phenotype, populated the tumor, and impeded tumor control by a simultaneous, RT-induced CD8+ cytotoxic T cell (CTL) response.

ZMYND8 protects breast cancer stem cells against oxidative stress and ferroptosis through activation of NRF2

Journal of Clinical Investigation - Cardiology

Breast cancer stem cells (BCSCs) mitigate oxidative stress to maintain their viability and plasticity. However, the regulatory mechanism of oxidative stress in BCSCs remains unclear. We recently found that the histone reader ZMYND8 was upregulated in BCSCs. Here, we showed that ZMYND8 reduced ROS and iron to inhibit ferroptosis in aldehyde dehydrogenase–high (ALDHhi) BCSCs, leading to BCSC expansion and tumor initiation in mice.

p40 homodimers bridge ischemic tissue inflammation and heterologous alloimmunity in mice via IL-15 transpresentation

Journal of Clinical Investigation - Cardiology

Virus-induced memory T cells often express functional cross-reactivity, or heterologous immunity, to other viruses and to allogeneic MHC molecules that is an important component of pathogenic responses to allogeneic transplants. During immune responses, antigen-reactive naive and central memory T cells proliferate in secondary lymphoid organs to achieve sufficient cell numbers to effectively respond, whereas effector memory T cell proliferation occurs directly within the peripheral inflammatory

How does low quality signal affect ECG analysis and practical tips to reduce it

Cardiomatics

The quality of the ECG signal is an important factor affecting the accuracy of analysis and proper interpretation, particularly for long-term ECG monitoring such as with Holter monitors or ECG patch devices. Misinterpretation can lead to a wrong diagnosis and consequently the selection of inappropriate treatment. The purpose of this article is to discuss possible ways of improving the quality of ECG signals in order to obtain more reliable results.

Cytoplasmic retention of the DNA/RNA-binding protein FUS ameliorates organ fibrosis in mice

Journal of Clinical Investigation - Cardiology

Uncontrolled accumulation of extracellular matrix leads to tissue fibrosis and loss of organ function. We previously demonstrated in vitro that the DNA/RNA-binding protein fused in sarcoma (FUS) promotes fibrotic responses by translocating to the nucleus, where it initiates collagen gene transcription. However, it is still not known whether FUS is profibrotic in vivo and whether preventing its nuclear translocation might inhibit development of fibrosis following injury.

Efficacy of colchicine in addition to anakinra in patients with recurrent pericarditis

Aim Anakinra, an anti IL-1 agent targeting IL-1 alfa and beta, is available for the treatment of recurrent pericarditis in cases with corticosteroid dependence and colchicine resistance after failure of conventional therapies. However, it is unclear if the combination with colchicine, a non-specific inhibitor of the inflammasome targeting the same inflammatory pathway of IL-1, could provide additional benefit to prevent further recurrences.

METTL14-mediated m6A epitranscriptomic modification contributes to chemotherapy-induced neuropathic pain by stabilizing GluN2A expression via IGF2BP2

Journal of Clinical Investigation - Cardiology

Epigenetics is a biological process that modifies and regulates gene expression, affects neuronal function, and contributes to pain. However, the mechanism by which epigenetics facilitates and maintains chronic pain is poorly understood. We aimed to determine whether N6-methyladenosine (m6A) specifically modified by methyltransferase-like 14 (METTL14) alters neuronal activity and governs pain by sensitizing the GluN2A subunit of the N-methyl-d-aspartate receptor (NMDAR) in the dorsal root gangli

Tumor-educated Gr1+CD11b+ cells drive breast cancer metastasis via OSM/IL-6/JAK–induced cancer cell plasticity

Journal of Clinical Investigation - Cardiology

Cancer cell plasticity contributes to therapy resistance and metastasis, which represent the main causes of cancer-related death, including in breast cancer. The tumor microenvironment drives cancer cell plasticity and metastasis, and unraveling the underlying cues may provide novel strategies for managing metastatic disease. Using breast cancer experimental models and transcriptomic analyses, we show that stem cell antigen-1 positive (SCA1+) murine breast cancer cells enriched during tumor prog
