Are you able to walk for miles on a treadmill, but can barely ascend a few flights of stairs? I explain to Marty Gonzalez, KRON 4 Morning News Weekend anchor, why stair climbing is so different from walking — and how it not only benefits your life but your sex life as well.😉
Stair Climbing vs. Walking
Stair climbing improves cardiorespiratory fitness. It is officially classed as a “vigorous” form of exercise. Stair climbing is a more POWERFUL form of walking because it:
Stair Climbing and Sex
Researchers in Canada monitored healthy male volunteers averaging age 64 while they walked, lifted weights, or climbed stairs. Stair climbing was the most demanding. Stair climbing was:
- Twice as taxing as brisk walking on level ground.
- 50% harder than walking up a steep incline or lifting weights.
- Faster at attaining peak exertion than walking (thus, explains the “huffing and puffing” going upstairs).

If you’re experiencing heart attack symptoms, aspirin is the BEST form of first aid. But all aspirins are not alike nor are all methods of taking aspirin alike. Join alongside KRON 4 Morning News anchor, Marty Gonzalez, in taking this lifesaving quiz!
Aspirin can stop an impending heart attack. A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. Most heart attacks develop when a cholesterol-laden plaque in a coronary artery ruptures. Plaque deposits are hard on the outside and when this outer shell ruptures (cracks), platelets rush to the area in an effort to ‘patch’ the ruptured area.
Platelets (or “thrombocytes”) are disc-shaped components in the blood that aid in clotting. Aspirin, an anti-platelet, helps inhibit platelet activity. As a clot grows, it blocks an artery. When the artery is completely blocked, cardiac tissue dies from the lack of blood supply and you have a heart attack.
NOTE: Ibuprofen is an anti-inflammatory, and acetaminophen is an analgesic. They are NOT anti-platelet drugs.
A Clot Grows Minute by Minute!
Aspirin can help stop the platelets from forming a larger clot if you take the aspirin BEFORE the clot gets too big. Time is of the essence, so it’s critical to know how the aspirin works the fastest.
QUIZ — Question #1
What is the best DOSE of aspirin to take during a possible heart attack?

Ever wonder what your blood pressure numbers mean? Here’s an explanation using a water faucet and pipe to demonstrate. And now there’s a THIRD pressure that’s important to your overall health and is worth monitoring as well.
What’s Your Pulse Pressure?
Pulse pressure is the numeric difference between systolic and diastolic blood pressure.
Predictor of Heart Attacks and Cardiovascular Disease
A resting pulse pressure in sitting position in healthy adults is about 30-40 mm Hg. For adults over age 60, especially men, a pulse pressure higher than 60 can be a useful predictor of heart attacks or other cardiovascular disease.
- A greater pulse pressure indicates that your vessels are stiffer and more damaged.
- If the aorta becomes rigid, such as from atherosclerosis, a.k.a., “hardening of the arteries”, your pulse pressure would be very high.
- Per a meta-analysis of several studies of 8,000 elderly subjects, the combined results found that a 10-point increase in pulse pressure increased the risk of major cardiovascular complications and mortality by nearly 20%.
NOTE: A low pulse pressure (i.e., 25 mm Hg or less) may mean aortic valve stenosis or congestive heart failure where a low volume of blood is ejected per beat.
Causes of Arterial Stiffness
The most important cause of an elevated pulse pressure is arterial stiffening, in particular, stiffness of the aorta (the largest artery in the body). Arteries stiffen with age, just like tissues in your skin, lungs, heart, tendons, and joints, due to:
- Degeneration of elastin fibers
- Stiffer collagen
- Fatty deposits damaging the arterial walls and resulting in them being less elastic (atherosclerosis)
Results of Arterial Stiffness
- Your heart enlarges. When arteries stiffen and lose their elasticity, your heart must contract more forcefully with each heart beat in order for your blood to circulate adequately. The extra work that your heart must perform can lead to physical changes in the musculature of your heart (e.g., size and shape), specifically the lower chambers (the ventricles). It’s just like how your biceps get bigger that occurs when you exercise them harder.
- You’re prone to irregular heart beats (cardiac arrhythmias). If the remodeling also affects the upper chambers (the atria), it can disrupt the electrical pathways that generate the signals telling your heart when to contract.
- You’re at a higher risk of a heart attack and stroke. The cause of most cardiovascular events and cerebrovascular accidents is the growth and eventual rupture of arterial plaques.
Which Is the Better Pulse Pressure?
160/120 mm Hg OR 110/70 mm Hg? (The pulse pressure in each pair = 40 mm Hg.)
Higher systolic and diastolic pairs imply higher risk of heart attacks and heart disease

VIDEO: You may think you’re one of the lucky ones who can eat unlimited bags of chips and other troves of salt; and yet, it doesn’t affect your blood pressure. But according to research published in the American College of Cardiology, excess sodium can adversely affect other target organs even if you don’t have hypertension.
Studies show elevated sodium levels can cause the inner lining of blood vessels (called the endothelium) to “malfunction”. The following occurs as a result:
- Vessels stiffen. Arteries that become less elastic and lose their contractility (ability to fully contract and relax) make it harder for the heart to pump blood throughout the body. Eventually, the heart wears out (heart failure).
- Vessels become sticky. Think of the lining of your blood vessels as being slick like Teflon. An unhealthy endothelium is sticky like Velcro and causes plaque to attach. Plaque builds up in the brain too — leading to Alzheimer’s.
- The body breeds dangerous inflammation. Inflammation may cause plaque inside blood vessels to crack, rupture, and dislodge from arterial walls. The body responds like with any other injury by causing blood to clot. Clots clog up vessel freeways and block blood flow to the heart (heart attack) or brain (stroke). Inflammation is also the key reason behind why heart attacks are more likely to occur after getting the flu.
NOTE: Eating too much sugar can have the same effect on the endothelium as an excessive intake of sodium.
Research found that elevated sodium levels may increase the wall thickness of the heart’s main pumping chamber (left ventricle). This thickening can lead to cardiac issues, such as:
- Arrhythmia (abnormal heart rhythm)
- Heart attack
- Sudden cardiac arrest (sudden loss of heart function)
- Heart failure (inability of the heart to pump enough blood throughout the body)
High blood pressure is a major risk factor for this muscle tissue enlargement, but it was also found in healthy people with NORMAL blood pressure who consumed high amounts of sodium.
Healthy kidneys remove extra fluid and waste from the blood. Studies found that a high Continue reading “KRON 4 | Salt Affects More Than Blood Pressure”
If you’re experiencing “chest pressure” or “chest pain”, aspirin is the BEST form of first aid. But all aspirins are not alike nor are all methods of taking aspirin alike. Take the lifesaving quiz below…

QUIZ (3 questions):
1. Pick the METHOD that you think makes aspirin work the fastest*. That is, during a suspected heart attack, which of the following is the fastest way to reduce blood clot formation?
A. Swallow the aspirin with 4 oz. of water.
