A blood pressure of 140/60 is not a good reading. The top number (systolic) of 140 sits at the threshold for stage 2 hypertension, while the bottom number (diastolic) of 60 is technically normal but low enough to raise its own concerns. This combination, where systolic pressure is high and diastolic pressure is low, is called isolated systolic hypertension, and the unusually wide gap between the two numbers signals changes in your arteries that deserve attention.
What Each Number Means at 140/60
The American Heart Association classifies a systolic reading of 140 or higher as stage 2 high blood pressure. That top number represents the force your blood exerts against artery walls when your heart beats. At 140, your heart is pushing harder than it should with every contraction.
The bottom number, diastolic pressure, measures the pressure between heartbeats when your heart relaxes. A diastolic of 60 falls within the normal range (below 80), but it’s near the lower edge of what’s considered safe. Research published in the Journal of the American College of Cardiology found that when diastolic pressure drops below 60, the risk of subtle heart muscle damage roughly doubles compared to people with diastolic readings in the 80 to 89 range. European cardiovascular guidelines recommend keeping diastolic pressure at or above 70 during treatment, recognizing that going too low can reduce blood flow to the heart muscle itself.
Why the Gap Between the Numbers Matters
The difference between your systolic and diastolic readings is called pulse pressure. At 140/60, your pulse pressure is 80, which is significantly wider than the typical 40 to 60 range. A wide pulse pressure is one of the strongest predictors of cardiovascular risk in middle-aged and older adults. It’s associated with higher rates of heart attack, heart failure, and overall mortality.
This wide gap develops because arteries lose their flexibility over time. Healthy arteries stretch when the heart pumps and then gently recoil, which cushions the force of each heartbeat. When arteries stiffen, they can’t absorb that force, so systolic pressure climbs. At the same time, the loss of recoil means less pressure is maintained between beats, so diastolic pressure drops. The result is exactly the pattern you see at 140/60: high on top, low on the bottom.
What Causes This Pattern
The most common cause is age-related stiffening of the arteries. Over decades, calcium and collagen accumulate in artery walls, making them thicker and less elastic. This process accelerates in people with diabetes, chronic kidney disease, or thyroid disorders. Peripheral vascular disease and severe anemia can also contribute, though these are less common causes.
It’s also worth noting that isolated systolic hypertension has an unusually high rate of “white coat” effect, where readings in a medical setting run higher than they do at home. Studies using 24-hour ambulatory blood pressure monitoring found that roughly 50 to 60% of people diagnosed with isolated systolic hypertension in a clinic actually had normal readings outside of it. If your 140/60 reading came from a single office visit, home monitoring over several days gives a much more accurate picture.
Symptoms You Might Notice
Most people with a systolic reading of 140 feel nothing at all. High blood pressure at this level is typically silent, which is part of what makes it dangerous. Symptoms like headache, dizziness, chest pain, and vision changes generally don’t appear unless systolic pressure reaches 180 or higher, which constitutes a hypertensive emergency. The absence of symptoms at 140/60 doesn’t mean the reading is harmless. It simply means the damage is happening gradually, primarily through increased strain on your heart and blood vessels.
The Treatment Dilemma With Low Diastolic Pressure
Treating a reading like 140/60 is trickier than treating straightforward high blood pressure. The systolic number clearly needs to come down, but most blood pressure medications lower both numbers simultaneously. If treatment pushes diastolic pressure below 60, it can impair blood flow to the heart muscle, which receives most of its blood supply during the relaxation phase between beats. This creates a genuine clinical tension: the high systolic is directly linked to mortality risk, but the already-low diastolic limits how aggressively it can be treated with medication.
Research highlights just how common this dilemma is. Nearly 45% of patients with isolated systolic hypertension and low diastolic pressure remain untreated, largely because clinicians are wary of dropping diastolic pressure further. This makes lifestyle changes especially important for people in this situation, since they can preferentially lower systolic pressure without dragging diastolic pressure down as much.
What You Can Do About It
Exercise is one of the most effective tools for lowering systolic pressure. A large meta-analysis in the British Journal of Sports Medicine, covering hundreds of randomized trials, found that regular aerobic exercise reduces systolic pressure by about 4.5 points on average. Resistance training produced a nearly identical reduction of 4.6 points. These effects come from consistent training over weeks and months, not from a single workout. For someone at 140, that kind of reduction could bring systolic pressure closer to the stage 1 hypertension range or even below it.
Reducing sodium intake, maintaining a healthy weight, and moderating alcohol consumption all contribute to lowering systolic pressure as well. These interventions tend to have a more targeted effect on systolic readings than medications do, making them particularly valuable when diastolic pressure is already low. That said, a reading of 140/60 warrants a conversation about whether medication is also needed, especially if lifestyle changes alone don’t bring the systolic number down over a few months.
If you’ve gotten a 140/60 reading at a clinic, tracking your blood pressure at home for a week or two can help clarify whether the systolic number is consistently elevated or inflated by the clinical setting. Use an upper-arm cuff (not a wrist monitor), sit quietly for five minutes before measuring, and take readings at the same time each day. A pattern of systolic readings at or above 135 at home confirms the reading is genuine and not a white coat effect.
