Your heart health numbers (blood pressure, cholesterol, resting heart rate, blood sugar, BMI, and waist circumference) offer an early, measurable look at your risk for cardiovascular disease long before symptoms show up. Understanding what each number means, and where yours falls, makes it easier to catch small changes before they become serious problems. Residents of Macon, Warner Robins, Milledgeville, Dublin, Griffin, Forsyth, and the surrounding Middle Georgia area can turn to Middle Georgia Heart for local expertise to interpret these numbers and turn them into an actionable care plan.
Key Takeaways
- Blood pressure at or below 120/80 mmHg is ideal; 130/80 mmHg or higher signals hypertension.
- Resting heart rate between 60–100 BPM is normal for most adults; consistent readings outside that range deserve attention.
- LDL cholesterol should stay under 100 mg/dL, while HDL cholesterol performs better at 60 mg/dL or above.
- Triglycerides under 150 mg/dL support healthy cardiovascular function.
- Blood sugar and A1C matter for heart health, not just diabetes risk — a fasting glucose under 100 mg/dL and an A1C below 5.7% are the target numbers to hit.
- BMI and waist circumference offer additional context on weight-related cardiovascular risk.
- A single unusual reading isn’t necessarily alarming, but a pattern of elevated numbers, especially alongside symptoms, warrants a cardiology evaluation.
- Middle Georgia Heart offers local, board-certified cardiology care for residents throughout the practice’s Middle Georgia service areas.
Knowing your heart health numbers is one of the simplest ways to understand your risk for heart disease before symptoms ever appear. Blood pressure, cholesterol, resting heart rate, blood sugar, and a handful of other measurements act like a report card for your cardiovascular system. However, a lot of people have never had the numbers explained clearly.
Today, we’re looking at the eight numbers that matter most, what “normal” actually looks like, and when a number outside that range is worth a conversation with a cardiologist.
What Are Heart Health Numbers, and Why Do They Matter?
Heart health numbers are the measurable indicators that doctors use to assess how well your cardiovascular system is functioning. They include blood pressure levels, cholesterol levels, and heart rate, among others. Knowing their importance and tracking them regularly can help catch problems like hypertension, high cholesterol, or prediabetes years before issues progress into major complications like heart attack, stroke, or heart failure. The earlier these numbers are monitored, the more room there is to make changes that actually move the needle.
8 Heart Health Numbers to Know
1. Blood Pressure
Blood pressure readings consist of two numbers: the systolic pressure, or the pressure measured when your heart contracts to push blood through the arteries, and the diastolic pressure, or the pressure measured when your heart is at rest between beats.
A normal blood pressure reading is at or below 120/80 mmHg (millimeters of mercury).
Readings consistently at or above 130/80 mmHg fall into the hypertension range and increase strain on your heart and arteries over time, if not lowered.
However, readings too far below 120/80 mmHg can indicate low blood pressure, which indicates reduced blood flow.
Blood Pressure Reading Guide
- Low Blood Pressure: Lower than 90/60 mmHg
- Normal Blood Pressure: Between 90/60 mmHg and 120/80 mmHg
- Elevated Blood Pressure: Between 121/80 mmHg and 129/80 mmHg
- High Blood Pressure, Stage 1: Between 130-139/80-89 mmHg
- High Blood Pressure, Stage 2: 140+/90+ mmHg
- Hypertensive Crisis: 180+/120+ mmHg
2. Resting Heart Rate
For most adults, a normal resting heart rate falls between 60 and 100 beats per minute (BPM), with well-conditioned athletes often landing lower, in the 40s to 50s. A resting rate consistently above 100 BPM (tachycardia) or dropping below 60 BPM without explanation (bradycardia) is worth mentioning to a doctor.
People who experience a consistently high resting heart rate above 100 BPM or low resting heart rate below 60 BPM may experience frequent dizziness, shortness of breath, fatigue, and heart palpitations.
The possible outcomes of a consistently high resting heart rate can include long-term strain, increased risk of cardiovascular disease, heart failure, and premature death.
The possible outcomes of a consistently low resting heart rate can include arrhythmia (irregular heartbeat) development, heart failure, and cardiac arrest.
Resting Heart Rate Guide
- Bradycardia: Less than 60 BPM
- Normal: 60 – 100 BPM
- Tachycardia: 100 BPM or higher
3. Maximum & Target Heart Rate Zones
When it comes to elevated heart rate due to exercise, your estimated maximum heart rate is roughly 220 minus your age.
Target heart rate zones for moderate exercise typically fall between 50–70% of that maximum, while vigorous exercise pushes into 70–85%.
It’s important to know these zones to ensure your workouts are effective without overexerting an already stressed heart.
Maximum and Target Heart Rate Zones Guide
- Age 20: 200 BPM (Max.), 100-170 BPM (Target)
- Age 30: 190 BPM (Max.), 95-162 BPM (Target)
- Age 40: 180 BPM (Max.), 90-153 BPM (Target)
- Age 50: 170 BPM (Max.), 85-145 BPM (Target)
- Age 60: 160 BPM (Max.), 80-136 BPM (Target)
- Age 70: 150 BPM (Max.), 75-128 BPM (Target)
4. Cholesterol
Total cholesterol is the measure of the LDL cholesterol, HDL cholesterol, and other lipid components in your blood.
Total cholesterol levels under 200 mg/dL (milligrams per deciliter) are considered desirable. Between 200–239 mg/dL is borderline high, and 240 mg/dL or above is high. This number is a starting point, but it’s also important to look at the breakdown between LDL and HDL for a more complete picture.
LDL Cholesterol (“Bad” Cholesterol)
LDL (low-density lipoprotein) is the cholesterol that builds up in artery walls, forming the plaque that narrows blood vessels and raises heart attack risk.
LDL levels should generally stay under 100 mg/dL, especially for those with existing risk factors.
HDL Cholesterol (“Good” Cholesterol)
HDL (high-density lipoprotein) is the cholesterol that helps carry excess cholesterol away from the arteries and back to the liver.
Unlike LDL, a higher HDL level is better. Aim for 60 mg/dL or above; below 40 mg/dL for men or 50 mg/dL for women is considered a risk factor.
Cholesterol Guide
- Healthy Cholesterol Level:
- Total cholesterol under 200
- LDL cholesterol under 100
- HDL cholesterol 60 or higher
- At-Risk Cholesterol Level:
- Total cholesterol between 200-239
- LDL cholesterol between 100-159
- HDL cholesterol between 40-59 (men) or 50-59 (women)
- Dangerous Cholesterol Level:
- Total cholesterol 240 or higher
- LDL cholesterol 160 or higher
- HDL cholesterol under 40 (men) or under 50 (women)
5. Triglycerides
Triglycerides are the most common type of fat in the body that originates from the foods you eat—particularly fats and carbs.
A healthy triglyceride level is below 150 mg/dL (milligrams per deciliter). Elevated triglycerides, especially when paired with low HDL or high LDL, meaningfully raise the risk of heart disease and are closely tied to diet, alcohol intake, and blood sugar control.
Triglycerides Guide
- Normal: Less than 150 mg/dL
- Elevated: 150-199 mg/dL
- High: 200-499 mg/dL
- Dangerously high: 500+ mg/dL
6. Blood Sugar (Fasting Glucose & A1C)
Blood sugar, or your blood glucose, is the main sugar found in your bloodstream. It is derived from the carbs you eat and serves as your body’s primary source of energy as it fuels your cells.
A fasting blood sugar level under 100 mg/dL is normal; 100–125 mg/dL signals prediabetes, and 126 mg/dL or higher on repeated tests indicates diabetes. The A1C test, which reflects average blood sugar over three months, should ideally stay below 5.7%. Since diabetes significantly increases cardiovascular risk, your blood sugar levels should be monitored for your heart health, not just as a part of diabetes management.
Blood Sugar Guide
- Normal:
- Below 5.7% with an A1C Test
- Below 140 mg/dL 1-2 hours after a meal
- Between 70-99 mg/dL after fasting for 8+ hours
- Prediabetes:
- Between 5.7-6.4% with an A1C Test
- Between 140-199 mg/dL 1-2 hours after a meal
- Between 100-125 mg/dL after fasting for 8+ hours
- Diabetes:
- 7% or higher with an A1C Test
- At or above 200 mg/dL 1-2 hours after a meal
- Above 125 mg/dL after fasting for 8+ hours
7. Body Mass Index (BMI)
Your BMI is a helpful tool for estimating your overall body fat and assessing your risk of developing health issues, like heart disease, diabetes, high blood pressure, sleep apnea, and more. While BMI is a good baseline to know and pay attention to, it should not be treated as a “north star” of sorts when it comes to your overall health—meaning you should not focus solely on improving your BMI if you’re trying to become healthier. A BMI calculation only uses your weight and height, it does not factor in fat distribution, muscle mass, bone density, or any other critical factors that make up a complete health picture.
Calculating BMI
There are plenty of free BMI calculators online, but the formula for calculating your BMI is as follows:
- Imperial formula = (Weight in lbs. x 703) / (Height in inches)2
- Metric formula = Weight (kg) / Height2 (m)
So, let’s say someone 5’5” (1.65 m) weighs 150 pounds (68 kg). Their BMI calculation would be:
| Imperial | Metric |
| (150 x 703) / 65 x 65
|
68 / 1.65 x 1.65 |
| 105,450 / 4,225
|
68/2.7225 |
| BMI of 24.95*
|
BMI of 24.977* |
*Results are close but not identical due to rounding numbers during pound-to-kilogram and inches-to-meters conversions.
BMI Numbers Guide
- Lower than 18.5 BMI: low/underweight
- Between 18.5 and 24.9: normal/optimal
- Between 25 and 29.9: overweight
- 30 or higher: obese
Remember, BMI is only a baseline and guideline. It does not tell the whole story. For example, many highly muscular individuals are considered “overweight” or “obese” according to the BMI chart, because their muscle mass and bone density cause a higher weight, and the calculator does not account for that.
Your cardiologist will take into consideration your BMI along with other critical numbers when assessing your heart health.
8. Waist Circumference
Often overlooked, waist circumference can be a strong predictor of heart disease risk. Your waist circumference estimates the amount of visceral fat—fat that releases inflammatory chemicals, plays a role in hormonal imbalance, and contributes to the development of conditions like high blood pressure, heart disease, and diabetes—around your internal organs. Even individuals within a healthy weight range who have a normal BMI can have increased amounts of visceral fat, elevating their risk of developing a problematic condition.
Waist Circumference Guide
- For Men:
- Ideal or low-risk: less than 37 inches
- Increased risk: 37 to 40 inches
- Severe risk: higher than 40 inches
- For Women:
- Ideal or low-risk: less than 31.5 inches
- Increased risk: 31.5 to 35 inches
- Severe risk: higher than 35 inches
When to See a Cardiologist About Your Numbers
A single out-of-range reading on any of these 8 metrics is not necessarily cause for alarm. Numbers fluctuate with stress, hydration, activity, and several other factors. However, if you’ve tracked a pattern of elevated blood pressure, cholesterol, or blood sugar, or any other combination of out-of-range numbers, it warrants a full cardiology evaluation rather than taking a wait-and-see approach to your heart health.

Frequently Asked Questions About Heart Health Indicators
What is considered a normal resting heart rate for adults?
A normal resting heart rate for most adults falls between 60 and 100 beats per minute. Rates consistently outside this range should be discussed with a doctor.
What blood pressure number is considered too high?
Blood pressure consistently at or above 130/80 mmHg is classified as hypertension and increases the risk of heart attack and stroke over time.
What’s the difference between LDL and HDL cholesterol?
LDL is often called “bad” cholesterol because it contributes to plaque buildup in the arteries, while HDL is “good” cholesterol because it helps remove excess cholesterol from the bloodstream.
How often should I get my heart health numbers checked?
Most healthy adults should have blood pressure checked annually, cholesterol every 4–6 years (more often with risk factors), and blood sugar screened periodically starting in their mid-30s to 40s, or earlier with a family history of diabetes or heart disease.
Can heart health numbers be normal but still indicate a problem?
Yes, healthy heart-related metrics that fall within “normal” ranges can still represent risk when combined with family history, lifestyle factors, or symptoms, which is why a cardiologist’s interpretation matters more than any single number in isolation.
What should I do if my cholesterol or blood pressure numbers are borderline?
Borderline readings for blood pressure or cholesterol are often an early opportunity to make lifestyle adjustments, such as diet, exercise, or reduced sodium and alcohol intake, before medication becomes necessary. A cardiologist at Middle Georgia Heart can help determine the right approach.
