Newly-defined Cardiovascular-Kidney-Metabolic Syndrome (CKM) means physicians will be in close collaboration with clinical laboratories to make accurate diagnoses
In a presidential advisory, the AHA defines a newly described systemic health disorder called Cardiovascular-Kidney-Metabolic Syndrome (CKM). The syndrome “is a systemic disorder characterized by pathophysiological interactions among metabolic risk factors, CKD (chronic kidney disease), and the cardiovascular system leading to multi-organ failure and a high rate of adverse cardiovascular outcomes.”
A CKM diagnosis, which is meant to identify patients who are at high risk of dying from heart disease, is based on a combination of risk factors, including:
weight problems,
issues with blood pressure, cholesterol, and/or blood sugar,
reduced kidney function.
CKM is a new term and doctors will be ordering medical laboratory tests associated with diagnosing patients with multiple symptoms to see if they match this diagnosis. Thus, clinical laboratory managers and pathologists will want to follow the adoption/implementation of this new recommendation.
“The advisory addresses the connections among these conditions with a particular focus on identifying people at early stages of CKM syndrome,” said Chiadi Ndumele, MD, PhD (above), Associate Professor of Medicine at Johns Hopkins University and one of the authors of the AHA paper, in a news release. “Screening for kidney and metabolic disease will help us start protective therapies earlier to most effectively prevent heart disease and best manage existing heart disease.” Clinical laboratories will play a key role in those screenings and in diagnosis of the new syndrome.

Stages of CKM Syndrome
In its presidential advisory, the AHA wrote, “Cardiovascular-Kidney-Metabolic (CKM) syndrome is defined as a health disorder attributable to connections among obesity, diabetes, chronic kidney disease (CKD), and cardiovascular disease (CVD), including heart failure, atrial fibrillation, coronary heart disease, stroke, and peripheral artery disease. CKM syndrome includes those at risk for CVD and those with existing CVD.”
The five stages of CKM syndrome, which the AHA provided to give a framework for patients to work towards regression of the syndrome, are:
Stage 0: No CKM risk factors. Individuals should be screened every three to five years for blood pressure, cholesterol, and blood sugar levels, and for maintaining a healthy body weight.
Stage 1: Excess body fat and/or an unhealthy distribution of body fat, such as abdominal obesity, and/or impaired glucose tolerance or prediabetes. Patients have risk factors such as weight problems or prediabetes and are encouraged to make healthy lifestyle changes and try to lose at least 5% of their body weight.
Stage 2: Metabolic risk factors and kidney disease. Includes people who already have Type 2 diabetes, high blood pressure, high triglyceride levels, and/or kidney disease. Medications that target kidney function, lower blood sugar, and which help with weight loss should be considered at this stage to prevent diseases of the heart and blood vessels or kidney failure.
Stage 3: Early cardiovascular disease without symptoms in people with metabolic risk factors or kidney disease or those at high predicted risk for cardiovascular disease. People show signs of disease in their arteries, or have heart function issues, or may have already had a stroke or heart attack or have kidney or heart failure. Medication may also be needed at this stage.
Stage 4: Symptomatic cardiovascular disease in people with excess body fat, metabolic risk factors or kidney disease. In this stage, people are categorized as with or without having kidney failure. May also have already had a heart attack, stroke or heart failure, or cardiovascular conditions such as peripheral artery disease or atrial fibrillation.
“We now have several therapies that prevent both worsening kidney disease and heart disease,” said Chiadi Ndumele, MD, PhD, Associate Professor of Medicine at Johns Hopkins University and one of the authors of the Circulation paper, in a news release. “The advisory provides guidance for healthcare professionals about how and when to use those therapies, and for the medical community and general public about the best ways to prevent and manage CKM syndrome.”
According to an AHA 2023 Statistical Update, one in three adults in the US have three or more risk factors that contribute to cardiovascular disease, metabolic disorders, or kidney disease. While CKM affects nearly every major organ in the body, it has the biggest impact on the cardiovascular system where it can affect the blood vessels, heart muscle function, the rate of fatty buildup in the arteries, electrical impulses in the heart and more.
“There is a need for fundamental changes in how we educate healthcare professionals and the public, how we organize care and how we reimburse care related to CKM syndrome,” Ndumele noted. “Key partnerships among stakeholders are needed to improve access to therapies, to support new care models, and to make it easier for people from diverse communities and circumstances to live healthier lifestyles and to achieve ideal cardiovascular health.”
New AHA Risk Calculator
In November, the AHA announced PREVENT (Predicting risk of cardiovascular disease EVENTs), a tool that doctors can use to assess a person’s risk for heart attack, stroke, and heart failure. The new risk calculator, which incorporates CKM, allows physicians to evaluate younger people as well, and examine their long-term risks for cardiovascular issues.
Doctors can use PREVENT to assess people ages 30 to 79 and predict risk for heart attack, stroke, or heart failure over 10 to 30 years.
“Longer-term estimates are important because short-term or 10-year risk in most young adults is still going to be low. We wanted to think more broadly and apply a life-course perspective,” Khan said. “Providing information on 30-year risk may reveal earlier opportunities for intervention and prevention efforts in younger people.”
According to CDC data, about 695,000 people died of heart disease in the US in 2021. That equates to one in every five deaths. Clinical pathologists will need to understand the AHA recommendations and how doctors will be ordering clinical laboratory tests to determine if a patient has CKM. Then, labs will play a role in helping doctors monitor patients to optimize health and prevent acute episodes that put patients in the hospital.
OIG warns that without adequate clinical laboratory testing healthcare organizations could see more deaths and increased spending
Clinical laboratory leaders and pathologists know that lab test volume decreased dramatically during the early months of the COVID-19 pandemic. That was primarily because community lockdowns stopped people from seeing their doctors for the standard range of chronic health conditions, many of which require clinical laboratory tests for diagnosis and chronic disease management.
• 24% reduction in Medicare Part B test volumes in March • 53% in April • 30% in May
The decline of Medicare patients visiting clinical laboratories continued through the balance of 2020. During the first 10 months of the pandemic—March through December 2020—Medicare beneficiaries who pursued lab testing decreased by about 9% compared to the same 10-month period in 2019, according to a news release.
This is a strong indicator that the government’s response to the pandemic had a measurable effect on clinical laboratory testing volume among all age groups, especially among the elderly.
“The cumulative decline in lab test volume across all client labs for [March 9 to April 12] was just over 40%. But in that time, some of our lab customers were hit with a decline of maybe 50% to 60% in test volume,” Kyle Fetter (above), COO, XIFIN, told The Dark Report in 2020. Clinical laboratory testing that originates from a routine patient visit to a doctor—such as blood testing—may have been affected the most, Fetter explained. (Photo copyright: XIFIN.)
Clinical Laboratory Tests Key to Well-being of Patients with Chronic Conditions
The OIG study was limited to Medicare beneficiaries and thus did not provide information about testing fall-off among people who have private health insurance. But in “From Mid-March, Labs Saw Big Drop in Revenue,” Dark Daily’s sister publication The Dark Report reported early in 2020 on a 40% decline in test volumes and the pandemic’s varying effects on clinical labs, anatomic pathology (AP) groups, and AP subspecialties.
The OIG’s Report in Brief on its study recognized that medical laboratory testing is critical to helping healthcare providers manage chronic conditions that affect patients’ well-being and increase their healthcare costs.
“Lab tests are important for beneficiaries with chronic medical conditions, which are associated with hospitalizations, billions of dollars in Medicare costs, and deaths,” the OIG said.
“The information may be useful to stakeholders involved in ensuring that beneficiaries avoid the potential bad outcomes that may result from missing or delaying appropriate care,” the report noted.
Overall, 23.7 million Medicare beneficiaries received medical laboratory tests during the first 10 months of the pandemic, down 2.4 million from 26.1 million in 2019, the OIG reported.
Overall Medicare lab test volume and spending also declined during the reported period:
Part B clinical laboratory tests for Medicare beneficiaries decreased 15% from 419.9 million tests in 2019 to 358.4 million tests in the first 10 months of the pandemic.
Medicare spending for these tests decreased 16% from $6.6 billion in 2019 to $5.5 billion during the first 10 months of the pandemic.
“OIG’s audit of Part B clinical laboratory tests, reimbursed under the Clinical Laboratory Fee Schedule (CLFS) is a useful benchmark for how Medicare beneficiaries received fewer lab tests during the pandemic, especially during the early months,” said Robert Michel, Editor-in-Chief of Dark Daily and The Dark Report.
Medical Laboratory Tests That Were Down Most During COVID-19
The following 10 clinical laboratory tests experienced a 10% or more decline in Medicare beneficiaries seeking them during the pandemic period as compared to pre-pandemic, according to the OIG report:
Comprehensive urine culture test fell 16% to three million Medicare patients.
Uric acid level blood down 13% to 1.9 million Medicare beneficiaries.
Evaluation of antimicrobial drug decreased 17% to 1.74 million Medicare patients.
Folic acid level down 12% to 1.73 million Medicare beneficiaries.
Urinalysis manual test plunged 28% to 1.4 million Medicare patients.
Beyond Medicare, Clinical Laboratory Test Volume Dropped 40%
OIG was not the only organization to analyze medical laboratory testing volume during the pandemic’s early phase.
The Dark Report correlated data tracked by XIFIN, a San Diego-based health information technology (HIT) company providing revenue cycle management services to clinical laboratories and pathology groups. XIFIN’s collected data showed a steep drop in routine test volume as COVID-19 testing ramped up.
“Starting in the third week of March, we saw medical laboratories suffer a sharp drop in routine testing. But at about the same time, many labs began to offset those revenue losses with testing for the novel coronavirus,” Kyle Fetter, XIFIN’s then Executive Vice President and General Manager of Diagnostic Services told The Dark Report in 2020. Fetter is now XIFIN’S Chief Operating Officer.
“Over four weeks beginning March 9, we saw a cumulative drop of over 40% in test volume from all of our lab clients,” he added.
According to XIFIN’s data, lab specialty organizations experienced the following drop in routine testing during the period March 9 to April 16, 2020:
58% at clinical laboratories.
61% at hospital outreach laboratories.
52% at molecular and genetic testing laboratories.
44% at anatomic pathology (AP) groups.
70% to 80% at AP dermatology and other AP subspecialties.
Many medical laboratories are still recovering from the COVID-19 pandemic’s effects on testing volume.
Notably, the OIG’s report acknowledges the importance of adequate clinical laboratory testing and declares that—without these essential lab tests to manage some healthcare conditions—the healthcare industry could see increased morbidity, deaths, and Medicare spending.
The Technion breathalyzer would give pathology groups and medical laboratories unprecedented ability to support physicians in diagnosing and treating cancers, chronic diseases, and other illnesses
Readers of Dark Daily know that several pathology research teams in America and the UK are developing breath analyzer tests that can detect everything from lung cancer to early-stage infections. Clinical laboratories will soon have a plethora of breath-related tests from which to choose. Now there’s a new kid on the block. A breathalyzer test that can detect up to 17 distinct cancerous, inflammatory, and neurological diseases!
Assuming the cost per test was at a competitive level to existing technologies, what would give this new diagnostic system appeal to physicians and patients alike is that it would be a non-invasive way to diagnose disease. Only a sample of the patient’s breath would be needed to perform the assays.
Researchers at the Israel Institute of Technology, or Technion, published the results of their study in ACS Nano, a monthly journal of the American Chemical Society devoted to “nanoscience and nanotechnology research at the interfaces of chemistry, biology, materials science, physics, and engineering.” (more…)
Developed by researchers at Emory University, Children’s Healthcare of Atlanta, and the Georgia Institute of Technology, the anemia test device is awaiting clearance by the FDA
New diagnostic technology may shift some hemoglobin testing for anemia out of clinical laboratories and into near-patient settings. It may also be possible to use this new diagnostic device for patient self-testing.
The developers describe this as a new, easy, inexpensive point-of-care test (POCT) that detects anemia. The device may be available as early as 2016. It is possible for the test to be used in situations where resources are low and illiteracy is high.
One Medicare contractor is proposing a new policy that would effectively end payment to labs and physicians for routine testing for Vitamin D deficiency. In its proposed local coverage determination (LCD), the Medicare carrier indicates that it would cover Vitamin D testing only for patients with chronic kidney disease, osteomalacia, hypercalcemia, and rickets. The LCD states that other testing for Vitamin D would be denied.
The draft (or proposed) LCD is dated February 6 and was posted on the Web site of National Government Services (NGS), one of the nation’s largest Medicare contractors. Medicare has asked for comments through February 21. If accepted as proposed, the denials for routine Vitamin D testing would begin on June 1, according to the LCD. In the posted draft, Medicare added a disclaimer saying that LCDs are not necessarily a reflection of the current policies or practices.
National Government Services (NGS) serves 200,000 providers and suppliers, along with nearly 24.5 million Medicare beneficiaries in 25 states and five U.S. territories. Not all Medicare providers will be affected by the LCD that NGS posted. Other Medicare carriers may have posted a similar LCD.
The draft of the NGS LCD says, “Measurement of vitamin D levels is indicated for patients with chronic kidney disease, osteomalacia, hypercalcemia, and rickets. Measurement of vitamin D levels is not indicated for screening. Measurement of any other Vitamin D metabolites (CPT codes 82307 & 82652) is not indicated, and will be denied.”
The draft LCD further states, “An excess of Vitamin D is unusual, but may lead to hypercalcemia. Vitamin D deficiency may lead to a variety of disorders, the most infamous of which is rickets. Treatment of Vitamin D deficiency is relatively straightforward, negating the need for measuring Vitamin D levels in many cases. Evaluating patients’ Vitamin D levels is accomplished by measuring the level of 25-hydroxyvitamin D. Measurement of other metabolites is not medically necessary.”
The Vitamin D Council, a nonprofit organization in Atascadero, California, reported the news on February 13. “If this rule passes, the change will quickly extend to all Medicare districts,” predicted the newsletter. “Private insurers will then follow suit, denying payment for Vitamin D blood tests, even for the diagnoses of Vitamin D deficiency. This rule change flies in the face of an enormous amount of research, some of it published in the last few months. For example, several weeks ago, the British Journal of Cancer reported that in men with prostate cancer, those with highest Vitamin D blood levels were seven times more likely to survive than were men with the lowest levels.”
It may be that Medicare officials are reacting to the significant increase in the volume of Vitamin D testing seen during the past two years. Much of this increased test volume is a result of ongoing media coverage about the importance of Vitamin D and new stories encouraging people to visit their doctors and request that their Vitamin D levels be checked.
For the laboratory industry, this is not an auspicious development. In the past, Medicare has used restrictions on coverage as a way to constrain utilization of certain procedures, thus helping it to control costs. Some lab industry experts are already speculating that this may be the reason why, at this time, one of Medicare’s largest carriers has published a proposed LCD that would limit reimbursement for Vitamin D testing only to a limited number of clinical situations. The Dark Report and Dark Daily will follow this developing story closely in the coming weeks
