Hi:
"What tests need to be done to check for this (ex. stress test, echo..)"
There's the non-invasive nuclear stress test (gated-SPECT scan with Cardiolite or Myoview), and to image plaque build-up, there is non-invasive 64-slice Cardiac CT, which allows doctors to view/examine the heart and the
coronary arteries in never-before-seen detail.
Far better yet, the newer blazingly fast (benefit of less radiation exposure to the patient, and less contrast media) 320-slice Cardiac CT scanner can measure subtle changes in blood flow, or minute blockages forming in blood vessels, no bigger than the average width of a toothpick (1.5 mm) in the
heart, and the brain
Additionally, it has been known for quite some time now that atherosclerosis begins (the process/progression of) at a very early age, even as early as in the pre-teen/teenage years.
Studies performed in the past have shown fatty streaks (represents the earliest precursor to plaque development and plaque is the pathological hallmark of atherosclerosis) as the beginning of atherosclerosis in the coronary arteries. Soft plaque (more dangerous and unpredictable than hard or calcified plaque) is the early stage of atherosclerosis.
"Is cardiovascular disease a cholesterol thing?"
It is only a piece of the puzzle.
There over
four dozen risk factors, markers, indicators for cardiovascular disease, some iffy/questionable, new, novel emerging, with more certainly to come.

Also, as reported, a risk factor merely increases the probability that one will develop cardiovascular disease, BUT doesn't 100% guarantee that one will develop it,
nor does its absence (or even the absence of ALL known risk factors) 100% guarantee that one won't have a heart attack or brain attack/stroke.
"And what type of diet should we do?"
Here's one to consider -
Nothing complicated...just plain 'n simple
Heart-Healthy Foods
Avoid foods high in saturated fat and cholesterol.
Choose skim or low-fat milk, low-fat yogurt and reduced-fat cheeses. Eat more fish and poultry.
Limit servings to five to seven ounces a day.
Trim visible fat. Limit egg yolks.
Substitute two egg whites for one whole egg or use an egg-substitute. Eat more fruits and vegetables, whole grains, breads and cereals.
Use less salt and fat.
Season with herbs and spices rather than with sauces, gravies and butter.

Best of luck to your husband and you down the road of life.

Good to know, for the primary and secondary prevention of heart attack and brain attack/
strokeEpidemiologic studies (EDS) have revealed risk factors (encompasses some new, novel or emerging) for atherosclerosis, typically affecting the carotid, coronary and peripheral arteries, which includes age, gender, genetics (gene deletion, malfunction or mutation) , diabetes (considered as being the highest risk factor), smoking (includes second and thirdhand), inactivity, obesity (a global epidemic, "globesity"), high blood pressure (hypertension), Low HDL (now questionable, according to recent studies) high LDL, small, dense LDL, RLP (remnant lipoprotein), high Lp(a), high ApoB, high Lp-PLA2, high triglycerides, HDL2b, high homocysteine (now questionable), and high C-reactive protein (CRP/hs-CRP).

TALK to your
DOCTOR and
ASK QUESTIONS. Studies show that patients who
ask the most questions, and are most assertive, get the best results. Be vigilant and speak up!"
