Study Shows 'Mystery' Heart Attacks are Almost Non-Existent Without These Four Risks

A massive health data analysis involving over 9 million adults in the U.S. and South Korea has strongly reinforced the crucial role of four well-known risk factors in cardiovascular disease. The study found that nearly every major heart attack, stroke, or heart failure event was preceded by one or more of these four conditions.

The Four Primary Culprits

The research revealed that a combination of these four modifiable risk factors preceded 99 percent of all cardiovascular events recorded during the long-term study:

1. High Blood Pressure (Hypertension)
2. High Cholesterol
3. High Blood Sugar Levels
4. Tobacco Smoking (past or current)

Even among women under 60—the group with the lowest risk—more than 95 percent of cardiovascular events were linked to one of these existing risk factors.

Hypertension: The Leading Indicator

Of the four factors, high blood pressure was the most common precursor. Over 93 percent of individuals in both countries who suffered a heart attack, stroke, or heart failure had hypertension beforehand.

Cardiologist Philip Greenland of Northwestern University emphasized the study’s clarity, stating, "We think the study shows very convincingly that exposure to one or more nonoptimal risk factors before these cardiovascular outcomes is nearly 100 percent."

The Path Forward: Focus on Control

The findings challenge recent claims suggesting a rise in cardiovascular events occurring without any established risk factors. The study authors suggest that previous research may have missed diagnoses or overlooked risk levels that were just below the official clinical threshold.

The clear public health takeaway is this: managing these modifiable risks is the key to prevention. As Dr. Greenland advises, the goal now should be to focus intensely on controlling these factors instead of getting sidetracked by pursuing other risk factors that aren't easily treatable or proven to be causal.
