Cardiac Death Foils Medical Tracking in Football, All Sports

Risk of Sudden Death Understated in Football, Say Experts

Information Barriers, Autopsy Limits Promote Short Data

Sample 31 Player Cases Led by Cardiac Deaths, 2014 To-Date

By Matt Chaney

Posted Friday, October 24, 2014

As concern spikes again for deadly injuries in American football, field collisions have killed from two to five teenagers thus far in 2014, pending further analysis, and an exact number may remain in question.

Actual football mortality constitutes a much bigger picture, meanwhile, through incalculable player deaths that are indirectly related to the game.

Minimally two dozen American football players have succumbed in sudden death this year. Most of the cases are perplexing, challenging for accurate diagnosis and impractical for linking to football, according to contemporary studies and authorities.

Record-keeping is stifled, resulting in significant under-reporting of deaths overall in American sport, especially for cardiac disease, say experts.

For American football, sudden cardiac death (SCD) has been marginally recorded over some 120 years of casualty reporting−while likely being the leading cause of mortality in the game.

And a particular, robust SCD class has been practically excluded, left undocumented: Those active football players who die without  physical exertion, in daily life outside game activities.

Actually, say experts, an athlete’s restful or normal state can combine with previous exertion to induce cardiac arrest in some variations.

“Yes…,” affirms Dr. Kimberly G. Harmon, of the University of Washington, a leading researcher in sudden death among athletes, “exercise can cause changes in the heart in some conditions that may make SCD more likely either at rest or at death.”

This year at least seven American football players have died during sleep and minimally five have collapsed at home, on campus, or while shopping. See their cases amid the 2014 summaries below, hyper-linked to news reports.

The dozen dead were schoolboys and collegiate players who participated regularly in training sessions and games. Each was hours or days removed from his last athletic exertion.

Nine more players have collapsed during football-specific activities, such as games and practices, then died.

Additional cases likely have occurred this year, sudden deaths of active football players, but information is hindered, leading to skewed recording and analysis−and weak prevention.

Privacy law is one limitation but the research field relies too heavily on inconsistent news media, which traditionally generate the lot of football’s catastrophic casualties to become recorded. Thus final statistics are short regarding millions of players, most prepubescent.

“Current methods of data collection underestimate the risk of SCD,” conclude Harmon et al., in the group’s landmark 2011 research on collegiate sports. “Accurate assessment of SCD incidence is necessary to shape appropriate health policy decisions and develop effective strategies for prevention.”

“Deaths in high school athletes may be even less likely to be identified by media reports as opposed to higher-profile NCAA athletes,” the researchers surmise in their article for Journal of The American Heart Association.

Faulty U.S. Death Investigations Impact Medical Data on Sports

Proper postmortem exam is problematic for American SCD casualties in general, not only athletes. America’s current death-investigation system struggles with “widespread dysfunction,” as documented by government and media reviews in the past decade.

Only about 9 percent of all deaths are autopsied in this country, and cardiac disease can elude identification and diagnosis even under pathology exam.

“The coroner-medical examiner system in the United States is highly variable in quality,” says Harmon, the MD and professor of sports medicine and family medicine at UW, via email. “Coroners are often elected or appointed officials with their only requirement being graduation from high school.”

“In many cases (of sport SCD) forensic pathologists are not performing the autopsies and most of the time cardiac pathologists are not involved.”

The basic mission of coroner and ME offices nationwide is to rule natural causes or foul play in a death, “and not necessarily the actual pathology,” notes Harmon.

Verifying a possible sport link is impractical, typically impossible.

“Often the training of the pathologist is limited and budgets to run (microscopic) histology−which is critical in making a correct (SCD) diagnosis−are limited,” notes Harmon, who encounters the issues in her review of college cases.

“Often experts will come to different conclusions as to etiology or not be able to make a definitive call on cause of death.”

Common thread is lack of evidence and sound conclusion, for SCD incidents in football players, like 2013 prep fatalities reported in Michigan and North Carolina. For the latter case, The Fayetteville Observer editorial board criticized state pathologists and procedures.

“When young football player Evan Raines died last year during practice at Seventy First High School, his family had to wait more than a year to find out why,” the newspaper editorialized on Oct. 5, continuing:

“But they weren’t singled out for what appears to be a glacial work pace at the N.C. Medical Examiner’s Office. … And they weren’t singled out, either, for an autopsy report that was vague and incomplete. That, we have learned, is the prevailing condition, too.”

In Missouri, a local coroner acknowledges knowing little but to declare cardiac arrest as cause in the recent death of 22-year-old international student Kazadi Mutombo. The ruling was based on hearsay that the fit and athletic young man collapsed in workout clothes after visiting the YMCA in Joplin.

Autopsy proved fruitless; the coroner’s consultant pathologist detected negligible evidence of harm to Mutombo’s heart, which “appeared to be in good shape.”

“There’s just certain things you don’t find out from autopsies, and you’ll never know,” says Newton County coroner Mark Bridges.

Accurate Death Analysis Crucial to Surviving Family Members

Researchers estimate almost a third of SCD cases in athletes under age 35 produce “negative autopsy” results for the different forms. State-of-the-art, costlier analysis is needed.

“Because electrical and other (cardiac) conditions will not be detected, it is not unusual for a routine autopsy to conclude that the cause of death was indeterminate,” states a Michigan study.

“In such cases, heritable conditions such as cardiac ion-channel disorders are suspect and genetic analysis could help to elucidate the cause of death and prevent future deaths in families at risk.”

The call is universal among experts, to overhaul SCD tracking in sports such as American football, foremost for preventing congenital health calamities among athletes and their families.

Genetically inherited cardiac conditions include most cardiomyopathies, like “enlarged heart” or HCM, and the “channelopathies,” heartbeat malfunctions caused by the organ’s electrical current, becoming increasingly detectable in advanced assays.

“In the past decade, the emergence of the channelopathies, in particular long QT syndrome and catecholaminergic polymorphic ventricular tachycardia, has transformed the importance” of advanced analysis, observes Dr. Mary N. Sheppard, of the Department of Histopathology at Royal Brompton Hospital in London.

“Sudden unexpected death during exercise particularly can, in many families, bring to their attention a hitherto unsuspected cardiac condition which is inherited and may be diagnosed by screening first-degree family members,” Sheppard writes for her 2012 analysis published in British Journal of Sports Medicine.

“Missed diagnoses (or) wrong diagnosis can have catastrophic consequences for families in which other members are at risk of sudden death because they carry the defective gene for that condition.”

31 Death Cases Among Football Players, 2014 To-Date

This collection of death cases among active American football players in 2014 is a sampling of public reports, online news. This analysis does not purport to present any  accurate number or estimation of deaths caused or related to football activities.

See 31 annotated cases below, including fatal casualties of brain bleeding, cardiac disease, heatstroke, and pulmonary embolism, culled from reports in Google banks since January.

Twenty-seven teenagers are among this sample 31 deaths, which are comprised of 1 youth football player, 2 middle-school students, 19 high-school players, 8 collegiate players, and 1 adult in flag football. Case capsules are wholly constructed of news content.

The information requires medically specialized followup, vetting by a multi-disciplinary team that would include accredited epidemiologists and a cardiac histopathologist, among experts, for scientific qualification beyond raw data, which is news content.

No such research team has yet been funded and assembled for American football.

Additional deaths among active football players appear online: suicides, drug overdoses, and more unexpected casualty.

Further deaths reported around the sport, including of coaches and referees, also do not appear below.

Brain Bleeds Among American Football Players, 2014

By Matt Chaney

Posted Monday, October 13, 2014

Last week a Texas boy became another severe brain casualty among American football players this year.

Details are sketchy for what led Clay Carpenter, 12, to collapse twice during football practice at Eustace Middle School last Tuesday night.

Carpenter was transported by ambulance to a local emergency room then flown by helicopter to a major trauma center in Dallas.

The boy was responsive following emergency brain surgery at Children’s Medical Center in Dallas, said his mother. “We’re just thankful he’s awake,” Leticia Carpenter told The Athens Review.

Leticia Carpenter said the injury “didn’t appear to have occurred after a collision with another player.”

As young Clay Carpenter remains hospitalized, at least six additional survivors of severe brain bleeds among American football players are known publicly, based on online reports thus far in 2014.

Recovery continues for all seven. See the annotated brain-bleed cases at bottom, along with capsules on one stroke victim and more casualties among football players in 2014.

Additional severe brain injuries have likely occurred and some will become public in future calendar years, beyond 2014, as demonstrated by cases from years such as 2013, 2012 and 2011, emerging still in reports.

Regarding football of 2011, for example, several critical brain injuries were later revealed in locales such as California, Alabama, and North Carolina. Even the brain-bleed case of an NFL player, caused by congenital artery malformation and possibly related to football, was “kept quiet” for two years.

Further types of head injuries for football 2014, reported in Google banks thus far, include an orbital-lobe fracture of a college football player and  blindness of an eye for a prep.

Severe Brain Bleeds Reported Among Football Players in 2014

Cardiac Arrest Likely Kills Most in Football 2014

American football’s possible role in a player’s sudden death is difficult to assess, particularly in a case of cardiac arrest outside physical activity. But athletic exertion is presumably contributing to many player fatalities this year, among the sampling 21 cases in this review. 

By Matt Chaney

Posted Wednesday, August 20, 2014

American football, with but one player’s death of field collision so far in 2014, might be poised to inspire proclamations of “safer” play. Last year, eight players died of football contact, all teens.

But the violent game is only beginning its regular season, traditionally the deadliest calendar stretch. In 2013, for example, the second collision death did not occur until Aug. 16, opening a run of seven direct fatalities in 12 weeks of prep football.

And more young football players are dying unexpectedly in America—especially this year—amid circumstances such as collapsing during a workout, succumbing while asleep, and developing blood clots. These fatalities are largely unverifiable for solid link to the sport that poses bodily stresses beyond physical battering.

A 2014 sampling is below, 21 deaths of active players through Aug. 16, mostly teens, culled from reports online. Death investigation continues for many of these casualties while other cases have concluded without pathology exam.

When cause isn’t field contact, death investigation of an American football player meets obstacles for objective establishment or dismissal of a game link. Medical specialization is required for accurately diagnosing illness like cardiac arrest, for its varied forms, and the process optimally involves experts of multiple disciplines.

Postmortem analysis of a football player, however, is often left to unqualified officials who are merely available, such as a general physician or elected coroner—or no autopsy at all.

Bottom line, no research entity can accurately determine the true number of football-related deaths, and notably not the “National Center for Catastrophic Sports Injury Research” at the University of North Carolina in Chapel Hill. No party has succeeded despite a century of published statistics, incomplete yet widely repeated, because case-collecting cannot properly access and assess the sport’s vast domain.

The football data’s entire history is fault-ridden, in need of redefining and reclassification for disjointed and limited collecting since the Victorian Era, by parties such as news media, game-funded groups like the NCCSIR, and this reporter.

The problem is apparent in overview of football deaths to-date in 2014, particularly the select 21 cases below.

Cardiac arrest likely caused the majority of these deaths, which also include cases of heatstroke, apparently, but information is lacking in public reports.

Conjecture even lingers over the single collision fatality, Navy running back Will McKamey last spring, based on statements by his parents that seemingly absolve football for culpability.

Certainly, evidence of football’s role in many of these casualties will pass undetected, whether missed, lost or ignored.

Epidemiological study remains a lofty goal, therefore, on mortality risk and outcome in American football. Valid and reliable numbers on catastrophic casualties, including survivors, must be harvested from a injurious environment hosting four to five million players scattered over 50 states, with about 95 percent of the population being juveniles.

Such research, unforeseen at this time, would necessitate a massive commitment of money and expertise, along with extraordinary cooperation by athletes, families, and football officials.

The 2014 death cases below are compiled strictly of information available in Google banks, primarily news reports, and require qualified, specialized follow-up for medical designation.

Not included are the deaths of active football players such as suicides and drug overdoses.

My condolences to the families of deceased players.
