Chest pain and T wave inversion, NSTEMI?
Case submitted and written by Dr. Mazen El-Baba and Dr. Emily Austin, with edits from Jesse McLarenA 50 year-old patient presented to the Emergency Department with sudden onset chest pain that began 14-hours ago. The nurse alerted the MD because the patient was still symptomatic, diaphoretic and “looking unwell”. What do you think? ECG interpretation: sinus rhythm, normal conduction (PR, QRS, and QTc), normal axis, delayed R-wave progression, and normal voltages. There ’s primary TWI inferiorly (aVF and III) and V6, with reciprocal tall T-wave in lead I/aVL, and a Q wave in III. The...

Outpatient Vascular Care: Good, bad or ugly?
BY ANISH KOKA
Filling in the holes of recent stories in the New York Times, and Propublica on the outpatient care of patients with peripheral arterial disease
Most have gotten used to egregiously bad coverage of current events that fills the pages of today’s New York Times, but even by their now very low standards a recent telling of a story about peripheral artery disease was very bad.
The scintillating allegation by Katie Thomas, Jessica Silver-Greenberg and Robert Gebeloff is that “medical device makers are bankrolling doctors to perform artery clearing procedures that can lead to amputations...

Pulmonary Arterial Hypertension: Unraveling Its Impact On Heart And Lungs
Conclusion
Navigating the complexities of Pulmonary Arterial Hypertension (PAH) might seem daunting. However, with the right knowledge and proactive approach, it’s possible to manage the condition and maintain a good quality of life.
PAH, a unique type of high blood pressure affecting the arteries in the lungs, can put extra strain on the heart. Over time, this can lead to heart failure. The condition’s root cause may vary, from genetic factors to other health issues like heart defects, liver disease, or autoimmune diseases. Remember, sometimes the cause remains unknown, resulting in idiopathic pulmonary ...

Severe Chest Pain on ED Arrival, after Wellens ' waves Seen on Prehospital ECG
A 40-something woman called 911 in the middle of the night for Chest pain that was intermittent. On arrival, she complained of severe pain.The medics had recorded this ECG and were uncertain whether it was recorded during chest pain:Let ' s get a better image with use of thePM Cardio app:What do you think?There is deep T-wave inversion in proximal LAD territory (V2-V4, I, aVL) that is all but diagnostic of Wellens ' . This is acute ACS, but it almost always seen in a pain free state. Since the patient has active pain now, if this is indeed Wellens, ' she must be re-occluded at this moment. An ED...

Chest pain, and Cardiology didn ' t take the hint from the ICD
Submitted and written by Megan Lieb, DO with edits by Bracey, Smith, Meyers, and GrauerA 50-ish year old man with ICD presented to the emergency department with substernal chest pain for 3 hours prior to arrival. The screening physician ordered an EKG and noted his ashen appearance and moderate distress. Triage EKG:What do you think?Triage physician interpretation: -sinus bradycardia-lateral ST depressionsWhile there are lateral ST depressions (V5, V6) the deepest ST depressions are in V4. Additionally, lead V3 has ST depressions, which are always abnormal (recall that lead V3 will haveST elevation under nor...

Association of LDL-Cholesterol with Mortality
https://www.fightaging.org/archives/2022/12/association-of-ldl-cholesterol-with-mortality/
Researchers here report on a study of LDL-cholesterol and mortality risk in older people. As they note, data on this topic is conflicted once one moves beyond the matter of cardiovascular disease. Over a lifetime, higher LDL-cholesterol makes it easier to reach the tipping point at which cholesterol deposited in blood vessel walls produces en...

Non-Dividing Neurons Do In Fact Become Senescent, Impairing Brain Function
https://www.fightaging.org/archives/2022/12/non-dividing-neurons-do-in-fact-become-senescent-impairing-brain-function/
Cellular senescence is generally thought of as a characteristic of replicating cells; it is an end state reached when telomeres, reduced in length with each cell division, become too short. This is followed by programmed cell death ...

An elderly woman with acute vomiting, presyncope, and hypotension, and a wide QRS complex
Written by Pendell MeyersFamily of an elderly woman with many comorbidities called EMS when she suddenly experienced shortness of breath, nausea, vomiting, and near syncope. She was alert and oriented and hypotensive with initial BP 70/50. A 12 lead ECG was obtained by EMS and is shown below:What do you think?There is sinus tachycardia (do not be fooled into thinking this is VT or another wide complex tachycardia!) The ECG is diagnostic of LAD occlusion (or even left main occlusion possibly), with the classic pattern of RBBB and LAFB with huge concordant STE in V1-V2, I, and aVL, with reciprocal depression in mo...

10+1 Commandments For Companies Developing Wearable Health Trackers
Throughout the last couple of years, I have tested and used about 150 devices and gadgets that measure health parameters or vital signs. From the very first Fitbit to A.I.-driven portable ultrasounds, the evolution is real, and I am delighted to have had the opportunity to watch it first-hand.
I also use a dozen health trackers to live healthily on a daily basis. Even before the wearable revolution started to unfold – just as I described in The Guide to the Future of Medicine -, I used data in an Excel spreadsheet to know more about my health and boost my motivation. Nowadays, it is unimaginable for me to go out...

A man in his 30s with cardiac arrest and STE on the post-ROSC ECG
Conclusions: outpatients with witnessed cardiac arrest and primary PEA carry a high probability of Massive Pulmonary Embolism________________Case Continued:" Initial ROSC EKG showed what appeared to be in atrial fibrillation with inferior ST elevations, depressions in aVL, concerning for STEMI. "He had multiple cardiac arrests with ROSC regained each time. " Endotracheal tube re-intubation was confirmed multiple times, bilateral breath sounds, yet O2 saturation remained in the 50s and 60s. I was able to visualize the ETT on initial intubation pass through the cords however given his continued hypoxemia, I felt it...

Chest pain one day after a negative stress test
Discussion Points:The patient ’s ECG transmitted to ED providers by EMS showed T waves that are easily confused with the peaked T waves of hyperkalemia. Sometimes hyperacute T waves have this slimmer, taller appearance, and it can be difficult to distinguish them in these cases. The new STE in anterior leads helps to understan d these as hyperacute. Also, other signs of hyperkalemia were absent, as there was no P wave flattening or QRS broadening, bradycardia, new AV blocks or NSIVCD, bizarre QRS morphology, or Brugada patterning. Additionally the clinical context was clearly ACS in this case, and if there were remaining...

60 year old with vomiting, diarrhea, and syncope: is this Wellens? Is this type 2 MI?
Written by Jesse McLaren, with edits/comments by Smith and Grauer A 60 year-old patient with diabetes and ESRD presented with 24 hours of vomiting, diarrhea, weakness and then a syncopal episode. Vitals: RR 18, sat 98%, HR 103, BP 124/71 and temp 38.0. Here ’s their ECG: is this Wellens? There ’s borderline sinus tach, normal conduction, normal axis, and low voltages in the limb leads. The anterior leads have loss of R waves, mild convex ST segments and primary T wave inversion. In the context of QS waves, T wave inversion indicates old or subacute infarct, or reperfusion after signif icant infarc...

Fight Aging! Newsletter, June 27th 2022
In conclusion, this study confirms that innate immune training can be induced in aging healthy individuals as well as critically ill sepsis patients. We found that innate immune training can be induced regardless of age and there was no substantive difference in the immune trained phenotype as a function of age. We employed β-glucan as our immune training stimulus. The ability of glucan to induce the trained phenotype suggests that it may be possible to pharmacologically induce the immune trained phenotype in aging human immunocytes.
