The existence and political legacy of former Vice President Dick Cheney, who died on Nov. 4, 2025, on the age of 84, has been neatly documented. However his decades-long combat with coronary heart illness could also be much less preferred.
Cheney benefited from virtually each and every primary advance made in cardiovascular medication. Those breakthroughs enabled him to maintain an lively political profession and gave him further years of an relaxing existence after he moved clear of the political highlight.
As a heart specialist who makes a speciality of each sports activities medication and coronary heart illness, in addition to complicated coronary heart failure and transplant cardiology, I continuously supply handle sufferers who, like Cheney, are supported through tough drugs and procedures to lend a hand beef up coronary heart serve as.
Cheney’s passing supplies a possibility to mirror at the fast evolution in clinical generation, particularly previously half-century, that advanced the lifespan and total high quality of existence for Cheney, in addition to hundreds of thousands of coronary heart sufferers all over the world.

The formative days of cardiac medication
Cheney suffered his first of 5 coronary heart assaults at age 37, in 1978, when the usual of care basically concerned ache reduction and mattress leisure, and when clinical pros didn’t but have a transparent figuring out of what reasons coronary heart assaults within the first position.
Nowadays, medical doctors needless to say a coronary heart assault happens when blood glide thru an artery is blocked through a blood clot known as a thrombus and oxygen can not get to the center muscle. Believe a kink in a hose that stops water passing thru it. When the center muscle does now not obtain oxygen for an extended sufficient time period, the center muscle will die and a scar will shape.
Within the Nineteen Sixties and ’70s, on the other hand, medical doctors concept a thrombus used to be the results of – now not the reason for – a coronary heart assault.
It’s now transparent that the formation of a thrombus results in a coronary heart assault fairly than the wrong way round. That necessary lesson revolutionized the way in which medical doctors like me deal with sufferers with coronary heart assaults.

Large and small breakthroughs
Nowadays, we reopen arteries with stents. When stents aren’t to be had, we use tough medicines known as thrombolytics, or clot-busters, to damage down the thrombus. Some of these remedies appear common lately, but it surely wasn’t till 1988 {that a} pivotal learn about confirmed combining aspirin and streptokinase, a clot-buster drug, advanced survival after a coronary heart assault through virtually 50%.
Cheney had further coronary heart assaults in 1984, 1988, 2000 and 2010. Particularly, all however the final had been all over election years, underscoring the unfavourable results of tension on coronary heart well being. His coronary heart assault in 2000 befell because the courts labored to decide whether or not Al Gore or George W. Bush – with whom Cheney would transform vp – had received the presidential election.
As generation complicated over time, Cheney had more than one angioplasties – a process to open up narrowed or blocked arteries. All over an angioplasty, a process advanced within the Nineteen Eighties, coronary heart medical doctors would position a balloon fabricated from versatile polymers inside of an artery to open up and transparent the thrombus.
Whilst angioplasties had been useful, one of the most primary barriers used to be that the partitions of the artery would temporarily shrink again – referred to as recoiling – after the balloon used to be deflated.

How stents turned into mainstream
That limitation resulted in the idea that of stents – units that at the moment are continuously used to regard coronary heart assault sufferers.
Cheney’s first coronary heart assault in 1978 befell neatly sooner than the primary stents turned into to be had.
Stents began out as steel, tubelike buildings that cardiologists used to open up narrowed or blocked blood vessels. The unique stents, fabricated from stainless-steel, fastened the issue of blood vessels recoiling.
However through the years, cardiologists discovered that stents transform stenotic, that means they themselves would transform slender, making it tricky for blood to glide thru them. This downside used to be solved with the creation of drug-eluting stents, that have a polymer that coats the steel struts of a stent and forestalls stenosis from happening.
Drug-eluting stents had been a game-changer and lowered the desire for repeated procedures through about 50% to 70%. Like hundreds of thousands of American citizens, Cheney gained a number of stents all over his lengthy combat with coronary heart illness.
Whilst stents are useful, every now and then sufferers require a surgical operation known as coronary artery bypass graft. Center surgeons carry out this process when there are blockages that angioplasty or a stent can not repair, or when there are too many blockages within the coronary heart arteries.
In 1988, at age 47, Cheney underwent a quadruple bypass operation to lend a hand repair blood glide to his coronary heart following his 3rd coronary heart assault.

Scuffling with coronary heart illness
Regardless of the most efficient efforts of cardiologists, many sufferers with coronary heart illness, like Cheney, cross directly to expand coronary heart failure.
There are two primary varieties of coronary heart failure. One – known as coronary heart failure with preserved ejection fraction – happens when the left ventricle, the most important and most powerful chamber of the center, turns into stiff and not able to calm down.
The opposite kind – coronary heart failure with lowered ejection fraction – happens when the left ventricle turns into enlarged and weakened, and fails to pump blood successfully.
Each varieties of coronary heart failure make it tricky for the center to adequately pump blood right through the frame. Cheney, like hundreds of thousands of other people right through the arena, suffered from a dilated and weakened coronary heart.
Thankfully, now there are a number of categories of medicines used to regard the type of coronary heart failure that Cheney suffered from.
There are 4 primary varieties of medicine that coronary heart failure cardiologists use to control sufferers with this situation, that are known as the “four pillars” of coronary heart failure control. Those medicines paintings in combination to scale back the quantity of tension positioned at the coronary heart and to create an atmosphere that is helping a weakened coronary heart pump blood extra successfully right through the frame.
Thank you to those 4 drugs sorts, hundreds of thousands of sufferers with dilated, susceptible hearts live for much longer with a better high quality of existence and staying out of the medical institution. A few of these medicines are extensively utilized for sufferers with stiffened hearts, however there’s a large number of ongoing analysis to raised know how to deal with sufferers with that more or less coronary heart failure.
Regardless of using medicines to regard dilated, susceptible hearts, some sufferers be afflicted by endured weakening of the center muscle and growth to end-stage, or complicated, coronary heart failure. When this occurs, there are most effective two remedy choices to be had. Those choices are a mechanical pump or a coronary heart transplant.
Center transplantation is the gold-standard, most well-liked remedy choice for complicated coronary heart failure that effects from a dilated, weakened coronary heart.
In 2023, there have been about 4,500 coronary heart transplants within the U.S. and about 2,200 in Europe. On moderate, sufferers are living neatly over a decade with a coronary heart transplant, and lots of will cross directly to are living for 20 to 30 extra years.

An oz. of prevention is price a pound of remedy
Benjamin Franklin famously quipped, “An ounce of prevention is worth a pound of cure.”
In an interview with “60 Minutes” in 2013, Cheney mentioned his coronary heart illness used to be the results of genetics and an dangerous way of life. He admitted that he drank beer, ate fatty meals and likewise smoked 3 packs of cigarettes in step with day.
Thousands and thousands of other people around the U.S. and Europe have a way of life this is very similar to that of Cheney’s previous to his coronary heart transplant. Whilst coronary heart sufferers take pleasure in medicines, stents and surgical procedures, preventive methods can’t be underestimated.
Virtually all primary well being organizations, together with the American Center Affiliation, American Most cancers Society and the Division of Well being and Human Products and services, counsel 150 mins a week of moderate-intensity workout.
This advice interprets to a brisk stroll about half-hour in step with day, 5 days a week. This stage of workout results in huge will increase in survival and preservation of total well being right through a life-time.
Whilst Cheney lived thru 5 coronary heart assaults, the purpose for sufferers and their medical doctors is to keep away from the primary. Medical advances in cardiology have resulted in a dramatic growth in survival and high quality of existence for hundreds of thousands of other people, however preventive measures are nonetheless through a ways top-of-the-line lifesaving measure.
