A recent scientific study has identified key warning signs that often precede heart attacks and strokes, potentially enabling earlier intervention and reducing mortality rates. These conditions remain leading causes of death worldwide, making early detection crucial.
The research highlights elevated blood pressure, increased cholesterol levels, and high blood sugar as prominent indicators. Researchers emphasize that the majority of heart attacks and strokes occur after the presence of these risk factors. A team from Yonsei University in South Korea noted that these factors are modifiable, advocating for enhanced early detection and management strategies.
The study involved analyzing health records of over 9 million individuals in South Korea and approximately 7,000 in the United States, spanning up to two decades. The research focused on four primary factors preceding heart attacks: blood pressure, cholesterol, blood sugar, and smoking. The study particularly emphasized the increased risk associated with elevated levels of these factors.
The findings revealed that 99% of patients who experienced a heart attack had at least one suboptimal risk factor, and 93% had two or more. Dr. Philip Greenland from Northwestern University stated that the study provides clear evidence that exposure to one or more modifiable risk factors is almost invariably present before a cardiac or vascular event.
The research further indicated that 90% of patients had at least one high-risk factor before their first heart attack. The focus now, according to the researchers, should be on managing these modifiable factors to mitigate the risk of heart attacks and strokes. Early intervention and lifestyle changes can significantly impact patient outcomes.
This study underscores the importance of regular health check-ups and proactive management of risk factors to prevent potentially life-threatening cardiovascular events.
