Heart disease is the leading cause of death in the United States, and most of what drives it is measurable and modifiable. The four numbers to know are your blood pressure, your cholesterol, your blood sugar, and your waist. The four habits are movement, food, sleep, and not smoking. None of that is surprising, which is precisely the problem — it is easy to know and easy to postpone.
The unglamorous truth: there is no supplement, superfood, or device that competes with managing blood pressure and staying active. This article is about doing the boring things deliberately.
Know your numbers
You cannot feel high blood pressure, high cholesterol, or high blood sugar. All three do damage silently for years. A single clinic visit establishes all of them.
| Number | Aim for | How often |
|---|---|---|
| Blood pressure | Under 120/80 | At least annually; more often if raised or treated |
| Cholesterol (LDL especially) | Depends on your overall risk — discuss with us | Every 4–6 years from age 20; more often with risk factors |
| Blood sugar (A1C) | Under 5.7% | From age 35, or earlier with risk factors |
| Waist circumference | Under 40in (men) / 35in (women), roughly | Whenever you are weighed |
“Depends on your risk” is the honest answer on cholesterol. An LDL that is fine for a healthy 35-year-old is not fine for someone with diabetes and a family history. This is exactly the conversation a primary care visit is for.
The eight levers
1. Move 150 minutes a week. Moderate activity — brisk walking counts — spread across the week, plus muscle-strengthening twice weekly. This is the single best-evidenced intervention on this list, and the biggest gains come from going from *nothing* to *something*, not from going from good to excellent. If 150 minutes sounds impossible, start at 10 minutes a day.
2. Eat mostly plants, fish, and whole grains. The Mediterranean and DASH patterns both have real trial evidence behind them. Practically: more vegetables, beans, nuts, olive oil, and fish; less processed meat, refined carbohydrate, and sugary drinks.
3. Cut the salt you did not choose. Most dietary sodium comes from packaged and restaurant food, not the shaker. Reading labels beats cooking blandly.
4. Do not smoke or vape, and avoid second-hand smoke. Quitting at any age improves cardiovascular risk quickly — within a year for much of the excess risk. We can help with this, and medication plus support works far better than willpower alone.
5. Sleep seven to nine hours. Short and poor-quality sleep independently raise blood pressure and cardiovascular risk. If you snore heavily, wake unrefreshed, or your partner has noticed you stop breathing, ask us about sleep apnoea — it is common, under-diagnosed, and treatable.
6. Keep alcohol modest. There is no cardiovascular benefit worth chasing, and heavier drinking raises blood pressure and triggers atrial fibrillation.
7. Manage weight realistically. A 5 to 10% loss produces measurable improvements in blood pressure, blood sugar, and cholesterol. That is a far more useful target than an ideal weight nobody reaches.
8. Take stress and isolation seriously. Chronic stress, untreated depression, and social isolation are associated with worse cardiovascular outcomes. This is not a soft add-on to the list.
If you are over 40
A few things change. Risk rises with age regardless of behaviour, so the value of knowing your numbers goes up. Ask us about your 10-year cardiovascular risk estimate — it combines your age, blood pressure, cholesterol, smoking status, and diabetes into a single figure, and it is the basis for deciding whether medication such as a statin is worth it for you.
Family history matters here: a parent or sibling with heart disease before 55 (men) or 65 (women) meaningfully raises your risk, and is worth telling us about explicitly.
And be alert to exertional symptoms — chest discomfort, unusual breathlessness, or jaw or arm ache that appears reliably with effort and eases with rest. That pattern is a warning, not a fitness problem, and it deserves an appointment this week.
Making it a family thing
Children form eating and activity habits early, and heart disease risk starts accumulating in childhood. The useful approach is environmental rather than instructional: keep fruit visible and accessible, eat together without screens, do something active as a family at the weekend, and do not make any food forbidden or moralised, which reliably backfires.
Modelling beats lecturing. Children whose parents walk, cook, and sleep properly tend to do the same.
Two Arizona specifics
Heat raises cardiac strain. Dehydration thickens the blood and makes the heart work harder. If you have heart disease, summer here is a genuine physiological stressor: exercise before 7am or after 7pm, hydrate deliberately, and know that some medications — diuretics and beta blockers in particular — change how your body copes with heat. Worth a medication review before summer.
Seasonal residents need a local provider. If you spend half the year here with a cardiologist in another state, nobody nearby has your baseline. Establishing care at our Medical Clinic means we already know your history if something happens at 2am.
Where to go
Call 911 for chest pain or pressure lasting more than a few minutes, especially with breathlessness, sweating, nausea, or pain spreading to the arm or jaw. Do not drive yourself.
Book our Medical Clinic to get your numbers, discuss your risk, review medications, and build a plan you will actually follow. Blood work is drawn and run in this building, so most results are back the same day. Call (602) 671-7981.
Our Emergency Room is open 24 hours at 9700 N. Saguaro Blvd if you are worried now: (602) 671-7990.
