A middle-aged man with acute chest pain.
A 50-something male had onset of chest pain 1 hour prior to ED arrival. It is constant, 9/10, left-sided CP that radiates into left arm and jaw. Endorses some associated SOB, but denies back pain, fever, cough, chills, leg swelling, or other new symptoms. Has never had this before. Takes metoprolol for HTN. Here is the triage ECG:What do you think?This was not identified as OMI by either the conventional algorithm nor the triage faculty physician.Smith: I think leads V3 and V4 are highly concerning, and all but diagnostic, for acute LAD occlusion. I would activate the cath lab, or at least look f...

75 year old dialysis patient with nausea, vomiting and lightheadedness
Written by Jesse McLaren A 75 year-old patient with diabetes and end stage renal
disease was sent to the ED after dialysis for three days of nausea, vomiting,
loose stool, lightheadedness and fatigue. RR18 sat 99% HR 90 BP 90/60, afebrile. Below is the 15 lead ECG. What do you think? There ’s normal sinus rhythm, normal conduction, normal axis,
normal R wave progression and normal voltages. There’s subtle inferior ST
elevation with straightening of the ST segment, reciprocal ST depression and T
wave inversion in aVL, and ST depression in V2. This is diagnostic of
infero-posterior OMI, but it is falsely n...

OMI Pocket Guide
📕OMI Pocket Guide TheOMI Pocket Guide (https://omiguide.org) is a user-friendly online resource designed to help healthcare professionals learn how to recognize subtle signs of acute coronary occlusion on the ECG which represent occlusion myocardial infarctions (OMI). Learning to recognize OMIs is an important clinical skill because it helps identify the subpopulation of " NSTEMIs " who are likely to be found with total thrombotic occlusion at the time of cardiac catherization.Although there are more criteria to consider when looking for OMIs compared to STEMIs, anyone can learn them, and this guid...

Blood Pressure Meds vs Blood Thinners: What ’ s The Difference?
Conclusion
In conclusion, while blood pressure medicines and blood thinners are both crucial to heart health, their roles and mechanisms of action are notably distinct. Blood pressure medication works primarily on the vascular system, aiding in reducing blood pressure by relaxing blood vessels or altering the heart’s function. On the other hand, blood thinners target the blood itself, working to prevent the formation of potentially dangerous blood clots.
Throughout this article, one thing becomes undeniably clear: the importance of regular consultations with your healthcare provider. When it comes to managing m...

Fight Aging! Newsletter, July 17th 2023
In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues.

Reviewing Efforts to Use Cells and Scaffolds to Regenerate the Heart
The heart is one of the least regenerative tissues in the body. Damage resulting from loss of blood flow during a heart attack leads to scarring and loss of function, rather than any meaningful degree of regeneration. While preventing the atherosclerosis that causes occlusion of blood vessels is the most desirable goal, finding ways to repair a damaged heart is also a high priority for the research community. Many groups have worked towards regenerative therapies based on delivery of cells and scaffolding material, even layers of artificial tissue made by combining the two, but progress has been frustratingly slow.

Stress Cardiovascular Magnetic Resonance Imaging for Stable Chest Pain
Stress cardiovascular magnetic resonance imaging is not as commonly used for evaluation of persons with stable chest pain as other modalities of non-invasive evaluation. Ricci and colleageus have reported a systematic review and meta-analysis on this aspect in JAMA Cardiology [1]. They evaluated 33 diagnostic studies including 7814 persons and 31 prognostic studies including 67,080 persons. The included studies were between 2002 and 2021.
The authors concluded that stress CMR had high diagnostic accuracy and had robust prognostication, especially when 3 Tesla MRI scanners were used. Myocardial ischemia and late gadoliniu...

Can You Run In Marathons With Hypertension?
Marathons and hypertension: Understand the risks, learn how to stay safe while running, and explore alternative activities to keep your heart healthy and thriving.
Quick Summary
Marathons pose risks for individuals with hypertension: The intense physical exertion can lead to sudden increases in blood pressure, dehydration, irregular heart rhythms, and strain on the kidneys, potentially causing serious complications like heart attacks or strokes.
Safety measures for hypertensive individuals: If participating in a marathon, monitor blood pressure regularly, follow a supervised training regimen, stay hydrated, w...

75 year old with 24 hours of chest pain, STEMI negative
Written by Jesse McLaren A 75 year old
with a history of CABG called EMS after 24 hours of chest pain. HR 40, BP
135/70, RR16, O2 100%. Here ’s the paramedic ECG (digitized by PMcardio). What
do you think? There ’s sinus
bradycardia, normal conduction, normal axis, delayed R wave progression, and
normal voltages. There are inferior Q waves and lead III has mild concave ST
elevation, with subtle reciprocal ST depression in I/aVL. This is diagnostic of
inferior OMI, likely from the RCA. The patient has a hi story of CABG so some of
these changes could be old, but with ongoing chest pain and bradycardia in a
hig...

Nocturnal Hypertension Unveiled: Protect Your Health While You Sleep
Is your blood pressure working the night shift? Let’s decode the mysteries of nocturnal hypertension together – from its symptoms and causes, to diagnosis and effective management. Sleep peacefully with our handy guide!
Quick Summary
Nocturnal Hypertension refers to high blood pressure that occurs at night, usually when blood pressure should naturally dip due to the circadian rhythm.

Can Febuxostat Protect From Contrast Induced AKI?
Contrast induced acute kidney injury is an important concern in patients undergoing percutaneous coronary interventions due the larger volume of contrast needed in comparison to diagnostic studies. It is more likely in patients undergoing primary angioplasty for acute myocardial infarction because of greater hemodynamic instability and lack of chance for protective measures like pre-procedure hydration.
A randomized controlled trial evaluated 120 patients with stage 3 chronic kidney disease who underwent PCI for acute coronary syndrome [1]. 60 patients received Febuxostat in addition to intravenous hydration and N-acetylc...

Causes of heart attack and cardiac arrest in teenagers
A heart attack occurs when blood flow to a part of the heart muscle stops. Heart attacks in teenagers can be caused by rare genetic diseases, such as familial homozygous hypercholesterolemia, which increases blood cholesterol levels, and some rare diseases that affect the blood vessels of the heart, such as Kawasaki disease.
Cardiac arrest means the heart stops working completely. A heart attack can lead to cardiac arrest. Inherited diseases like Congenital long QT syndrome and Brugada syndrome that cause cardiac arrhythmias and can also cause cardiac arrest in adolescents.

Another myocardial wall is sacrificed at the altar of the STEMI/NonSTEMI mass delusion (and Opiate pain relief).
I received the following text message with these 3 EKGs (providers text me ECGs all day every day; most are false positives; many are subtle true positives):" Hi Steve, here are 3 EKGs for you (my colleague ' s case). A 67 yo f developed chest pain this morning. "EKG #1Followed 15 minutes by this #2 EKG:Then the patient received aspirin andDilaudid (hydromorphone, same effect as morphine) and the pain went away and there was this 3rd ECG:Smith comment: hydromorphone will make any pain go away (or improve) without any improvement in the underlying pathology. Do NOT give it unless you are committed to t...
