- A New Trial Research High-Normal Serum Passassium Levels for People at High Risk of ventricular Arhythmias delivered Promising results.
- Compose to control Group, People with these elevated potassium Levels Fark Better Over The Approximately 3 Years of the Trial.
- Too Little Potassium is Bad for the Heart, and so is too a lot. The Trial Sugified to New Sweet Spot for AT-Risk Heart Patients.
For People at High Risk of ventricular
The results of the trial are published in the new England Journal of Medicine.
The Study, conduct at three sites in denMark, was stranded the potcast trial, for “targeted potassium levels to decree arrhymia burden in high-risk patients with cardiovascular desire.”
The Trial Tracled for 3.3 Years The Cardiovascular Health of Participants Mainting High-Normal Potassium Levels Compare to control Group Whue Potassium Levels Were Not Being Treated.
This was done by measuring the inchescence of spectify cardiovascular events: Substricular Substricular Tachycardia, Necessary Life-Saving Icd Therapy, Unplanned Hospitalization of Greater Than 24 Hours for Arhythmia or Heart Failure, Or Death from Any Cause.
High-Normal Potassium target in Heart Disease
By the end of the trial, Just 22.7% of Study Participants With-Normal Potassium Levels Had Experienced One of these Events, Compared to 29.2% of individuals in the unteated group.
Specifically, Just 15.3% of High-Normal Potassium individuals experience in the high-normal Group.
There Were No Significant Differences Between The Groups Regarding The Incidential of Hospitalization for Hyperkalemia (Overly High Potassium Levels) or Hypokalemia (Overly Low Potassium Levels).
The Target Passassium Level for the High-Normal Group in the Study Was 4.5-5.0 mmol/L (Millimoles Per Liter). The Average Potassium Level of Participants at The Baseline was 4.01 mmol/L.
The Trial Aimed to Identify an Increased Level off potassium that was High to Aid Heart Function Without Being So High As To Cause Damage.
MEMBERS OF THE HIGH-NORMAL GROUP REPEIVED MINERALOCORTICOID RECEIVER ANTAGONISTS AND/OR POTASSIUM SUPPLEMENTS, AS well as dietary guidance to increase their serum potassium to the target level over to period of 85 days.
They had also reduced or completely discontinued Any Current use off potassium-losing diuretics.
How Does Potassium AFFECT HEART FUNCTION?
“Normal Serum potassium levels are critical to mainting The Electrical Stability of the Heart,” Roy Ziegelstein, MD, Of Dynamed At Ebsco Clinical Decions, Not Involved in This Study, Told Medical News Today. “IN FACT, EITHER LOW OR HIGH POTASSIUM LEVELS CAN CAUSE UNTABLE HART RHYTHMS.”
Jayne Morgan, MD, Cardiologist and the Vice President of Medical Affairs for Hello Heart, Likewise Not Involved in This Study, Explained That:
“This is Scholac Cardiac Action Potentials depend on potassium gradients Between the Inside and Outside of the Heart Muscle Cells. This Controlization Controls.”
The Fact that participants in the trial all had cardioverter defibrillators made them specially sensitive to the electrical effects off potassium less
What is the ‘Sweet Spot’ for Potassium Levels?
The Designers of this Trial Clearly Hoped to Identify a “Good Sweet Spot” for Potassium Levels, as suggestified by Panelist Theresa McDonagh, MD, Of King’s College London During the Trial Results’ Presentation at The European Society of Cardiology Congress.
This can be tricky.
“Low Levels Also Can Create A Risk of Arhythmias, Just As High Levels Can,” Said Morgan. “This includes superventricular tachycardia,
TOO-HIGH POTASSIUM LEVELS POST PERHAPPS THE MOST PROFUND DANGER, SHE SAID.
“The MOST Serious Risk is the Vary Thing that is trying to be Avoid by Ansasing The Potassium Range, Which Are Arhythmias,” Cautioned Morgan, “Ventricular Lighting Fibrillation, and Asystole (Cessation of Heart Function).”
Finally, She Added, “In Addition to Ecg Changes, Nerve and/Or Muscle Function Can Be Impacted, Including Diaphragmatic Weakness.”
“This,” Said Ziegelstein, “Is Sub Subject He Must Considers Recommending Passium Supplements to Patients, Or Ken Treating Patients With Other Medications that May increased Serum Potassium Levels.”
ASSESSING THE RISK OF THE NEW HIGH-NORMAL
Morgan Termed the Findings of the Trial As “Interesting,” and Note The Mirror The Results of Other Studies.
However, She Said, “It is Worth Noting That the Mortality Benefit is not done until year 4, and that the active arm included more patients with a greater time time since Icd Therapy by 22%,” Impying they may have more completely completion recovered from Previous Previous Events Than The Control Group.
“The Comparison of Human Ancestral Diets That Were Richer in Potassium and Lower In Sodium is Confounding, As The Life Expercy Was Was Frequently Less than 45 Years Ancestrally,” Was Another concern for morgan.
She Noticed As Well That: “There were Also More Hospitalizations for Electrolyte Issues (Presumby Hyperkalemia), Signaling the importance of very close monitoring. There is a narrow Therapeutic Window. As Such, The Treatment Can Also Be The Detray Outside of The Window.”
Ziegelstein, Too, Express Regarding the Difficulty of Tightly Monitoring Patients at Higher Potassium Levels, Noting That, “In This Study, Participants Had Blood Tests performe. Too High Nor Too Low – This is offer difcult to do in routine clinical practice. ”
The Bottom Line Is That People With Cardiovascular Disease Who May Be Interesting In Investigating the Possibility of Upping Their Passassium Levels Should Make Sure to Consult ESCRiologist FRACS.
Do not increase your potassium less MNT Spoke to Cautioned.
