But new evidence has revealed that anyone infected with COVID is at higher risk for heart issues—including clots, inflammation, and arrhythmias (irregular beats)—a risk that persists even in relatively healthy people long after the illness has passed.

The SARS-CoV-2 virus enters the human body through the upper respiratory tract-the nose, mouth, and throat, and sometimes stays there. But other times it stealthily moves down the throat into the trachea, the bronchi, and finally the lungs.

There the virus creates inflammation that impairs the lungs’ ability to do their job- take oxygen from the air we breath and send it to the heart which pumps it through the aorta to all the other organs of the body.

Although inflammation caused by the COVID virus can damage other body organs, the most common causes of death in its victims are respiratory failure and/or cardiovascular disorders such as heart attack, heart failure, or stroke.

Even apart from COVID, diseases of the heart and lung are the leading causes of death all over the world. This post reviews 3 books I have read and reviewed that explain the intricacies of these two related and vital systems. One review is new, the other two have been previously published.

The Source of All Things

A Heart Surgeon’s Quest to Understand Our Most Mysterious Organ

By Dr. Reinhard Friedl, With Shirley Michaela Seul; Translated by Gert Reifarth

Originally published as Der Takt des Lebens. Warum das Herz unser wichtigstes Sinnesorgan ist

In his memoir, Dr. Reinhard Friedl introduces us to the heart, describing its unique role in the human body, one he considers the most important of any organ. He believes the heart is the “source of all life”.

Dr. Friedl describes the heart’s structure and basic function, in detailed but non-technical terms. He does not view the heart as a mere pump as it is often described, but as a turbine, an engine.

Then he whisks us into the operating room as he performs a middle of the night emergency surgery to save a man’s life by repairing his damaged aorta. Later, he travels to a home to resuscitate a 34-week premature baby who wasn’t breathing. He describes the challenge of performing a delicate heart surgery on a 24-week premature infant. In each case, he acted automatically, calling upon years of training, using his mind and hands with precise attention to details, focusing only on the patient’s open chest on the table.

But operating with his brain was not enough for Dr. Friedl. He realized as a heart surgeon he needed to know and use his own heart. He wanted to find out

“Can we sense thing consciously with the heart? May we act from the heart? Is there a connection between the voice of the heart and illnesses, between a fulfilling life and one full of suffering?”

He explored the answer through meditation and deep breathing. He dove into the connection between the heart and the brain, studying philosophy, neurology, genetics, and even quantum physics. He finally concludes

“The greatest challenge for modern medicine is to bring back together the fragments of the human being and integrate them in holistic medicine.”

Dr. Friedl’s story wanders at times, as did his journey to self-discovery. One chapter title, Farewell to the Artificial Heart, characterizes the journey he started and continues; reading his memoir may prompt you to start your own journey.

BREATH TAKING – a book review

We take 7.5 million breaths a year and some 600 million in our lifetime. Breath Taking is an exhaustive review of why and how our lungs work, and what happens to our lives when they are attacked and injured by disease.

This illustration, created at the Centers for Disease Control and Prevention (CDC), reveals ultrastructural morphology exhibited by coronaviruses. Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19).CDC/ Alissa Eckert, MSMI; Dan Higgins, MAMS

A researcher at the Johns Hopkins Bloomberg School of Public Health examined the long term effects of COVID on the heart.

“Until now, people who suffered mild or asymptomatic COVID-19 were thought to have dodged the brunt of the virus’s brutal side effects.

But new evidence has revealed that anyone infected with COVID is at higher risk for heart issues—including clots, inflammation, and arrhythmias (irregular beats)—a risk that persists even in relatively healthy people long after the illness has passed.”

Science-our friend, not foe

This post highlights the importance of science and technology, emphasizing that progress and prosperity are directly tied to advancements in these fields. We are indebted to scientists for modern conveniences and medical advances. One is the significant medical impact of Henrietta Lacks’ cells, unknowingly donated and immortal, which have led to several major scientific discoveries.

“Whoever desires progress and prosperity, whoever would advance humanity to a higher plane of civilization, must further the work of the scientist in every way he possibly can.“

You might think this is a recent statement, but it is not. It was written over a hundred years ago. Here is an expanded version taken from the original source.

Take from the air every aeroplane; from the roads every automobile; from the country every train; from the cities every electric light; from ships every wireless apparatus; from oceans all cables; from the land all wires; from shops all motors; from office buildings every elevator, telephone and typewriter; let epidemics spread at will; let major surgery be impossible—

all this and vastly more, the bondage of ignorance, where knowledge now makes us free, would be the terrible catastrophe if the tide of time should but ebb to the childhood days of men still living!…

Therefore, whoever desires progress and prosperity, whoever would advance humanity to a higher plane of civilization, must further the work of the scientist in every way he possibly can.

The Work of the Scientist. JAMA. 2022;327(9):882. doi:10.1001/jama.2022.0191

Originally Published March 4, 1922 | JAMA. 1922;78(9):649. (JAMA Revisited is transcribed verbatim from articles published previously, unless otherwise noted.)

Written in 1922, this author could not mention space flight, GPS, computers, CT and MRI scanners, modern drugs and surgical techniques, organ transplantation, DNA, and a myriad other modern conveniences we take for granted.

I don’t ride trains, I’m not sure what a “wireless apparatus” is, and I haven’t used a typewriter in years. I don’t understand the current aversion, suspicion, and contempt for those who study and work in the STEM fields-science, technology, engineering, and math.

But every time we use our mobile phones, computers, access the internet, or stream videos or music, we can thank the scientists who made it possible.

The Immortal Life of Henrietta Lacks 

I haven’t reviewed this book but I read it and wondered why I didn’t know this story before, a true account of a simple but strong woman whose death gave a priceless gift to science- immortal cells.

“Her name was Henrietta Lacks, but scientists know her as HeLa. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells—taken without her knowledge—became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than sixty years.

HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects; helped lead to important advances like in vitro fertilization, cloning, and gene mapping; and have been bought and sold by the billions. 

Yet Henrietta Lacks remains virtually unknown, buried in an unmarked grave.

As author Rebecca Skloot so brilliantly shows, the story of the Lacks family—past and present—is inextricably connected to the dark history of experimentation on African Americans, the birth of bioethics, and the legal battles over whether we control the stuff we are made of. 

Intimate in feeling, astonishing in scope, and impossible to put down, The Immortal Life of Henrietta Lacks captures the beauty and drama of scientific discovery, as well as its human consequences.” from Amazon
