Statistically, more of us will succumb to heart disease than any other cause. We can try to mitigate the odds with our diet and behavior but we can't control genetics.
I smoked those damn cigarettes for 20 years and drank myself into an ulcer and have never had any control of my diet yet I think I'm ok for now. I think if there are no underlying heart issues than it's ok to push one's body which is why I still do the rides I do. I don't see the point of worrying about it, I worry more about getting flattened by some moron who's texting while driving.

A pretty definitive summing up is here.
The best thing you can do is stay in shape.
Oh, and to answer the question, no. I worry about getting smashed by a motor vehicle operator.

I just finished a book entitled The Haywire Heart - How Too much exercise can kill you, and what you can do to protect your heart.
It's written by athlete cardiologists and Lennard Zinn, who many may know from his books and technical articles on cycling.
It has lots of actionable information for the masters athlete.
If you're a cyclist with concerns about your cardio health, I highly recommend getting a copy. It's available from velopress.
Here's a review of the book from cardiologist and athlete Larry Creswell, MD.

Stop changing the oil on your Toyota and it won't last as long as one which had proper maintenance.

We also know that raising heart rate for a short time through exercise results in a lower resting heart rate the remainder of the time. So let's compare two hearts: one belonging to a non-exerciser who's resting heart rate is 80bpm. (Higher end of normal range per Mayo Clinic) And one heart belonging to an athlete who works out and for 1 hour a day raises his heart rate to 160bpm, but as a result of this exercise, his resting HR is 60bpm. So, how many beats per day?
Non-exerciser: 80bpm x 60s/hr x 24hr/day = 115,200 beats per day
Exerciser: (160bpm x 60s/hr x 1hr of exercise) + (60bpm x 60s/hr x 23hr of rest) = 92,400 beats per day
Just a rough example, but something to think about.

If you're concerned about it, check with your doctor, especially if you have a personal or family history of heart problems. Otherwise, let your body be your guide.

Those in this thread with diagnosed arrythmias or coronary artery disease have reason to be careful in one way or another. The rest of us should not worry about going too hard, because we're probably not going hard enough.
I can't be bothered to look up and link the references, but you can google for them. There is decent evidence that brief periods of intense activity produces better health benefits for the elderly in terms of various metabolic markers, VO2 max etc than does extended moderate activity. And by intense activity I mean maxing out, going as hard as you can, for a minute or two at a time. And the evidence relating to increased incidence of arrythmias among endurance athletes appears to be related not to maximal efforts, but to going hardish - around threshold - for very long periods: we're talking ironman, pro cyclists, multiple marathons, that sort of thing.
It's likely that the best thing you can do for your heart health is to go steady most of the time but make sure you go very hard indeed for a few minutes a couple of times a week. A nice couple of hours ride at recovery pace with a sprint up a decent hill in the middle of it is probably ideal. For the record, I'm 65 and regularly see an HR in the 170s.

I'm not sure I would assume that, but let's say for argument's sake that it's true.

Mine wasn't amused either. Then he glanced at the history I had provided and he was concerned. But I'm 52. Most of us don't see 40, so I guess I'm doing ok.

I really do recommend asking your doc about having a scan to assess the status of your cardiac arteries. Why guess based on bloodwork?

The issue of exercise-related arrhythmias relates more to the faster end of the spectrum than to your average weekend duffer, who is far more likely to buy it from a coronary thrombosis, to wit, a plumbing, rather than an electrical, problem. So, there's a bit of an apples and oranges issue, which extends to the approach one might take to evaluating or mitigating risk.
I'm going through this currently, to rule out my PVCs being a symptom of something serious. Blood tests, check. ECG, check. Zio Patch, waiting for results. Stress test, pending. CT catheter, hope it doesn't have to go that far.

I think my heart does a good job of protecting itself, by causing me discomfort when it's stressed. My brain collaborates with my heart by throttling my desire for suffering. I'm just along for the ride, no pun intended.
