4 Heart Health Numbers Every Man Over 40 Should Know

Most guys know track their lifts, their steps, or even their sleep. But ask them what their last bloodwork said and you get a shrug.

After 40, a few lab numbers tell you more about long-term health than almost anything you can measure in the gym. Here are four worth knowing:

1. LDL cholesterol: the one most people have heard of. Your doctor will tell you what range is right for you, since it depends on your history.

LDL carries cholesterol through your blood, and when there’s more than your body needs, it can build up in artery walls as plaque over years. You won’t feel it happening, so a blood test is the only way to know. Under 100 mg/dL is generally considered optimal, but your doctor will set the right target for your history.

2. HDL cholesterol: the other side of the standard panel.

HDL helps carry cholesterol back to the liver, and higher levels are generally linked with lower heart risk. For men, under 40 mg/dL is considered low. It’s best treated as a clue about the bigger picture, since low HDL often shows up alongside high triglycerides and low activity.

3. Triglycerides: often overlooked, and closely tied to diet and activity.

Triglycerides are the fat your blood carries for energy, and they respond quickly to diet, alcohol, and activity levels. Under 150 mg/dL is normal, and 200 and above is high. Ask your doctor whether your test was fasting, since that affects the reading.

4. Blood pressure: not a blood test, but it belongs on the same list.

Blood pressure is the force of blood against your artery walls, and when it stays high, it quietly damages them and strains your heart. Normal is below 120/80, and 130/80 and above is considered high. Most men feel nothing until the damage is done, so checking it regularly matters.

Ranges are general reference points for adults, not a diagnosis. Your doctor will interpret your numbers in the context of your history.

Next time you’re at the doctor, ask for a copy of your results and ask: “Which of these numbers are you watching for me, and why?” Also ask whether other markers, like ApoB, make sense for your situation. It’s a simple conversation that most men never have.

These numbers matter more than you might think, especially for your longevity and long-term health.

And remember, you can't manage what you don't measure, so improving any of these starts with knowing what yours are.
